How it works
®
1. Upon entry, spring tension holds the
replaceable and adjustable cutting blade in the
extended position as it removes the burr on
the front of the hole.
2. As the feed load increases, the pre-set
spring tension is exceeded and the blade
retracts automatically as the tool passes
through the workpiece. (The crowned and
polished top surface of the blade will n o t mar
the inside surface of the hole.)
3. Spring tension again causes the blade to
extend as it emerges from the ID of the part;
the burr is removed on the back side of the
hole on the return stroke.
A one-pass solution
to your
hole-deburring
problems!

BURRAWAY tools are available in both inch and metric
programs (see tool specifications, pages 6–9). Tools for the
inch program feature imperial (inch) hardware (adjusting
screw); tools for the metric program have metric screws.
Both are available from stock at standard prices.

Burraway tools feature an inexpensive,
replaceable cutting blade which adjusts to
control the amount of edge break.
Burraway®
Design features
All BURRAWAY® tools operate on
the same basic principle, but vary
Type C
slightly in design as determined by
tool size:
Type A tools (inch program; for
hole sizes from .093 through .203
in.) and Type MA tools (metric
program; sizes from 2 to 5mm)
are a two-piece construction
(arbor assembly and adapter). All
Type A and MA arbor assemblies
are interchangeable with their
respective shank adapters.
Type B tools (inch program; for
hole sizes from .218 through .750
in.) and Type MB tools (metric
program; sizes from 5.5 through
19mm) are a single-piece
construction.
Type C tools (inch program; for
hole sizes from .750 through 2 in.)
and Type MC tools (metric
program; sizes from 20 through
50mm) are also a single-piece
construction.
A tension adjustment
mechanism controls the amount of
edge break for consistent results
from piece to piece. Types A, MA,
B, and MB tools have a tension
adjustment screw located in the
shank end; Types C and MC tools
control depth of cut with a tension
adjustment rod.
Blade options
BURRAWAY tools are
furnished with double-acting
blades for burr removal on both
the front and back sides of the
hole. Blades for front-cutting or
back-cutting only are available
from stock at no additional charge.
Type A
Various blade rake angles and
spring tension options are
available and recommended for
deburring specific material types
(see page 10).
Carbide-tipped blades are
available upon request for nominal
hole sizes of 3/16 inch (4.76mm)
and larger. TiN-coated blades are
also available upon request.

Blade data
Three blade styles
Blade replacement
Double-Acting (DA)
For deburring both front and
back of holes.
Blade replacement is easy for
tools in nominal sizes from 3.0mm
(.118 in.) and larger. When the tension adjustment screw, located in
the end of the shank on Type A
and B tools, is loosened
sufficiently, the open-ended slot
allows the blade to slide out freely.
The replacement blade is then
installed and the tension
adjustment screw retightened for
the desired amount of spring
tension.
Back-Acting (BA)
For deburring back of hole only.
Front-Acting (FA)
For deburring front of hole only.
Note: BURRAWAY blades for nominal tool sizes of
3/32 and 7/64 inch (.093 and .109) in our inch
program, and blades for 2.0 and 2.5mm tools in
our metric program, are designed with a pinhole
instead of a slot. The open-ended slot is not
feasible in this size range due to the small size of
the blade. The blade can only be replaced by
removing the pivot pin from the arbor, which may
cause breakage. We do not recommend blade
replacement in these smallest tool sizes. We
recommend that the entire arbor assembly be
replaced.
Blade recommendations for
various material types

Blade rake angles
The three styles shown above
are available from stock as
standard items, with positive rake
angles. Negative and neutral rake
blades are available from stock
upon request as a standard option
for certain material types (see
chart on the right); otherwise, the
positive rake blade will be supplied.
For Type C tools, loosen the
tension adjustment set screw
located on the O.D. of the arbor
and slide out both the Type C
blade and the tension adjustment
rod. Replace in reverse order.

equipment, CNC machines, or on
virtually any type of shop
equipment. No special operator
skills are required.

However, the blades can be
reground and reused. Blades can
generally take from five to ten
regrinds of .010 inch (0.25mm)
each before they must be
discarded. Regrind clearance
angles as shown in Figure 1 below.
The amount of stock removed
will vary with the hardness of the
material. Adjust the set screw in
the shank end of the tool to obtain
the desired edge break. (Caution:
Be careful not to over-adjust; if the
spring is compressed to a solid
condition, the blade will not be
able to retract.)
If adjustment fails to produce
the desired results, a different
blade rake angle or a light-duty
spring may be required. Please
submit part prints for development
of the most efficient tooling for the
application.

Blade life and regrinding
BURRAWAY blades generally
last about four to ten times longer
than the drill used to make the
hole. Due to the low cost of

Fast and easy adjustment
Tool maintenance
Our BURRAWAY® Kit contains five
deburring tools in popular hole sizes:
• 1/8 in. • 5/32 in. • 3/16 in.
• 7/32 in. • 1/4 in.
A replacement blade for each tool
is included. The kit is packaged in a
durable box. The BURRAWAY Kit
enables you to have on hand the
solution to burr removal problems for
hole sizes most frequently encountered.
Cross-hole deburring
Burraway tools will tend to cut
an elliptical chamfer when
deburring a hole drilled through
the wall of a larger hole (i.e., the
amount of edge break will be
inconsistent). If the ratio of the
main bore diameter “B” to the
cross-hole diameter “A” is less
than 3/1 (refer to Figure 2), the
Burraway is not recommended.
If the ratio is 3/1 or greater, the
standard Burraway tool should be
tested and may provide satisfactory
results. If not, consider using a
tool with a special Burraway blade
with a 45˚ angle, run at speeds
of 40-100 RPM; contact our
engineering department.
If the ratio is questionable, our
Burr-Off tool may be considered
(see page 12). While it will tend to
cut a greater ellipse, it will also
resist breakage on steep side
walls. Neither the Burraway nor the
Burr-Off is recommended for holes
that do not intersect squarely or
diametrically.

The BURR-OFF® operates on the same basic principle as the BURRAWAY®,
but is designed for high-production, automated deburring operations. The
open-slot design of the “clothespin tool” allows chips to clear easily, which
makes the tool ideal for automatic equipment and multi-spindle machines.
Just like the BURRAWAY, the BURR-OFF deburrs the front, back, or both
sides of holes in one fast pass.

Design features
The BURR-OFF® is a simple
one-piece construction. The
integral cutting edges can be
altered upon request for front or
back-cutting only.
All BURR-OFFS except CP-6
through CP-9 come equipped with
a sliding tension-adjustment
feature to control the amount of
edge break.
Standard and special tool

In addition to our standard
BURR-OFF tools, custom tools are
available upon request. Larger
sizes, altered standards, and
special designs can be supplied to
suit your requirements.

Micro-Limit
Micro-Limit
How it works
The MICRO-LIMIT is a precision
depth-control countersinking tool.
The tool consists of a drive with a
piloted countersink and a depthcontrol adjustment feature.
The tool is pre-set to the
desired depth of cut. The selected
setting is locked in for accurate
and consistent results from part to
part.
The pilot is engaged in the
hole. A stop collar seats on the
face of the workpiece; the tool
advances to countersink the hole
to the desired depth.

Design features
The Micro-Limit drive is
designed and built for rugged
production work. The thrust load is
taken up on ball bearings through
a hardened steel stop collar. The
drive shaft rides on needle
bearings. This design makes our
drive the longest lasting in the
industry.
Adjustment is in increments of
.001 inch (.025mm).
Three drive models cover a
wide range of hole sizes.
Countersinks
& pilots
An array of interchangeable
countersinks and pilots are
available as standard (refer to tool
specifications on page 18 ).
Countersinks are offered with
three standard angles. Special
angles and carbide-tipped countersinks are available upon request.
Pilots for hole sizes from .125 to
.500 inch (3.17 to 12.7mm) are
standard; intermediate sizes are
available upon request.

The MICRO-LIMIT is also
offered with an overtravel unit built
into the standard drive.* Ideally
suited to automatic applications,
the overtravel feature compensates for variations in part
thickness and for overtravel of the
machine spindle up to .125 inch
(3.17mm).
The MICRO-LIMIT with
overtravel also simplifies set-up for
applications on multiple spindles.

Ellipti-Bur
Ellipti-Bur
How it works
The ELLIPTI-BUR® is designed for
deburring irregular hole surfaces, such
as those which are generated by drilling
into curved surfaces, or by drilling at an
angle. The ELLIPTI-BUR enables the user
to perform these difficult deburring
operations quickly and accurately, and
without jigs, fixtures, or special operator
skills.
As the pilot of the tool is located in
the hole, the tool is seated and
centered. As the tool is advanced, the
pilot is forced into the tool body against
the shank spring, and the blade comes
into contact with the edge of the hole.
As the tool continues to advance, the
pilot is further pressed into the body and
the blade is driven into the workpiece.
The blade remains free to react to the
irregular surface geometry of the hole,
allowing for both radial and axial
displacement- radial displacement
resulting from the elliptical shape of
angularly-drilled holes, and axial
displacement (“rise and
fall”) from the saddleshaped configuration of
holes drilled in cylindrical
surfaces.
This automatic selfguiding feature produces
a relatively uniform break
on the edge of the hole.
20
®
Ellipti-Bur®
Design features
The ELLIPTI-BUR features a
spring-loaded and self-centering
conical pilot to locate and seat the
tool for consistent results. All
essential tool parts are hardened
and ground for durability.
Three models cover a range of
hole sizes from 5/32 to one inch
(3.96 to 25.4mm).
The blade, which has two
diametrically opposed cutting
edges, is made from hardened
high-speed steel and finish
ground. A supplemental surface
treatment provides for increased
wear resistance.

®
ELLIPTI-BUR tools can be
used on portable power tools and
drill motors, drill presses, automatic equipment, CNC machines, or
on virtually any type of shop
equipment.
The tool is fast, safe, and easy
to handle. The pilot engages the
hole. The blade, not the tool body,
reacts to accommodate the
irregular hole geometry.
Speeds and feeds
The most desirable speed for a
particular application can best be
determined by trial. Spindle
speeds must be relatively slow to
enable the blade to accommodate
a continuously changing path in
the course of each revolution.
The speed recommendations
below will serve as a guideline:
•Speeds up to 600 RPM are
generally recommended where
the following conditions exist:
(1) Where holes are drilled
into a flat surface at an
angle not exceeding 15˚.
(2) Where holes are drilled
into a cylindrical part with
a diameter which is 6 or
more times greater than
the hole size.
•Speeds of 100-300 RPM may be
required where more difficult
conditions exist, such as:
(1) Holes drilled at a severe
angle.
(2) Holes drilled into a
cylindrical part where the
diameter is less than 6
times the hole size.
contact pressure is required to
deburr and produce a small edge
break. The amount of stock
removal is determined by the
pressure applied and the dwell
time.
Application considerations
A proper drilling technique is
necessary in order to maximize
the effectiveness of the
ELLIPTI-BUR. The following
guidelines will help you avoid
creating an excessive burr:
•Drill points should have a 130150˚ included angle, rather
than the conventional 118˚.
•Slow-spiral drills generally
allow better breakthrough than
fast-spiral drills.
•A uniformly controlled feed rate
(preferably power feed) is
required in order to prevent an
accelerated advance of the drill
at the point of breakthrough.
•The workpiece should be held
securely.
Blade replacement and
regrinding
The ELLIPTI-BUR blade can be
easily replaced by following this
procedure (refer to the details
drawing on page 22):
1.Remove Detail 7 Retaining
Screw. (Note: Tool is springloaded.)
2.Remove Det. 6 Shank Spring
Assembly.
3.Remove Det. 3 Blade Spring.
4.Remove Det. 4 Chrome Steel
Retaining Ball.
5.Slide Det. 1 Pilot and Det. 2
Blade from Det. 8 Tool Body.
6.Remove Pilot from Blade. (Note:
spring-loaded.)
7.Replace Blade.
8.Reassemble in reverse order.
(Important: Blade must be
inserted in tool body so that it
can float freely.)
Replacement blades are
inexpensive; however, the blades
can be reground in the userʼs
shop. Please refer to Figure 3 for
proper regrind procedure.
Application restrictions
The ELLIPTI-BUR is generally
not recommended for:
•Extremely soft, ductile metals.
•Applications where the
diameter of a cylindrical part
having a cross-drilled hole is
less than 2-1/2 times the
diameter of the drilled hole.
(Note: The softer and more
ductile the material, the more
this limitation applies.)

The above steps can be repeated as many times as necessary,
depending upon the number of walls in the part. Work is
performed continuously, without having to stop the spindle.

1.
The tool should be running in a
spindle with the cutting blade in the
extended position. The tool is fed
into the workpiece. The burr on the
outer edge of the first wall is quickly
and easily removed.
2.The sliding sleeve is moved
backwards to retract the blade. The
workpiece is advanced to such a
position that, when the blade is again
extended by a forward movement of
the sleeve, it will lie between the two
walls. The burr on the inner edge of
the first wall is then easily removed.
3.Continued advancement of the tool
allows the inner edge of the second
wall to be deburred. The sleeve is
moved backwards once again to
retract the blade so that it can pass
through the hole in the second wall.
The blade is again extended to
deburr the outer edge of the second wall.
Nobur® Tool
Design features
The NOBUR Tool has a freerolling knurled sleeve, mounted on
ball bearings, which allows for fast
and easy manual retraction and
extension of the blade. The pilot is
chrome-plated for long tool life.
Standard sizes range from 3/32
to one inch (2.38 to 25.4mm).
Work lengths range from 9/16 to
4-3/4 inch (14.28 to 120.65mm).
Blade options
for intersecting holes
Three different blade options are
available for intersecting hole
applications. Blade selection is
based upon the ratio of the
diameters of the two holes (refer
to page 27).

Blade data
Blades for NOBUR® Tools are
manufactured from hardened and
precision ground high-speed steel.
Three styles are available:
standard, and two modified
designs (see below for application
parameters). For applications
other than intersecting holes, the
standard blade is used.
Blades for intersecting
hole applications
Intersecting holes can
sometimes create problems when
using the NOBUR Tool with the
standard blade. The following
guidelines apply:
Standard blades may be used
for intersecting hole applications
where the larger hole “B” is 12 or
more times greater than the
smaller hole “A” (refer to Figure 4).
Modified standard blades are
available from stock for intersecting
hole applications where the
following conditions exist:
•Modified blade No. 1 is
recommended for intersecting
holes where the diameter of the
larger hole “B” is between 6 to
12 times greater than the smaller hole “A.”
Figure 4
•Modified blade No. 2 is
recommended for intersecting
holes where the larger hole “B”
is 2-3/4 to 6 times greater than
the smaller hole “A.” (Operating
speeds from 25-75 RPM are
also recommended for applications within this range of intersecting hole diameter ratios.)
Note: The NOBUR Tool is not
recommended for lower ratios of diameter
or for holes which do not intersect
squarely.
27
Nobur® Tool
Tool operating
recommendations
Tool operation
NOBUR® Tools can be run on a
drill press, lathe, or any rotating
spindle.
Material types
NOBUR Tools can be applied on
steel, stainless steel, brass, bronze,
aluminum, or virtually any ferrous or
non-ferrous materials.
Speeds
Low operating speeds are
recommended for the NOBUR Tool.
A range of 50 to 650 RPM is suggested, with slower speeds required
for larger tool sizes and heavy parts.
High spindle speeds will not result
in faster production, since only three
or four revolutions of the tool are
required to remove the burr. High
spindle speeds are likely to dull the
blade edge, create excessive wear
on the pilot shaft, or cause chatter.
The part should be supported as
necessary.
Blade replacement and
regrinding
The NOBUR Tool blade can be
easily replaced by following this procedure (refer to the schematic drawing on page 26):
For tool numbers #DS 1/8 to #DS 10:
•Remove the back collar.
•Slide the knurled sleeve back to
where it just drops free onto the
smaller shank diameter.
•Restrict further movement of the
blade at this point, and complete
the removal of the sleeve.
•Lift the blade out and replace.
28
For tool numbers #AS 3/16 to #AS 1/2:
•Slide the knurled sleeve against
the back collar so that the blade
is retracted within the pilot shaft.
•Remove the pivot screw. This
frees the front collar and permits
the blade to be lifted out.
•Replace the blade. To
re-assemble, the cam edge of
the blade must be inserted so as
to depress the end of the spring
which extends beyond the
sleeve.
•Align the front collar and replace
the pivot screw. A zero (0) mark
is stamped on the front collar of
tools #AS 5/16 and smaller to
indicate that it is to be positioned
in line with the slot on the pilot
shaft.
For tool numbers #AS 9/16 to #AS 3/4:
•Remove the screw from the back
collar. Remove the back collar
and sleeve. Remove the pivot
screw from the front collar and lift
the blade out for replacement.
•To re-assemble, replace parts in
reverse order. Insert the blade
first in such a manner that the
spring is depressed.
sharp, since a dull blade takes
longer to cut and the operator will
tend to apply excessive pressure
against the work. Refer to Figure 5
for proper regrind procedure.
Short front pilot
It may be necessary to shorten
the front pilot to accommodate blind
holes or obstructions. The pilot
should be cut off beyond the slot
from which the blade projects.
Tool maintenance
Inspect the tool periodically for
chips and foreign particles in the
slot of the pilot shaft. Clean as
necessary.
A few drops of lubricating oil
applied between the sliding sleeve
and the back collar will extend the
life of the bearing.
Resharpening of the cutting blade is
accomplished by grinding the faces “G” and
“H”. The following table is offered as a guide
to original factory standards.
For tool numbers, #CS 13/16 to #CS 1:
•Slide the knurled sleeve against
the back collar. Remove the pivot
screw and lift the blade out and
replace.
•To re-assemble, the cam edge of
the blade must be inserted in
such a manner as to depress
the end of the spring which
extends beyond the sleeve.
Replacement blades for NOBUR
Tools are inexpensive; however,
blades may be reground in the
userʼs shop. The blade must be kept

Back-Spotfacing
& Chamfering TOOLS
Above: FlipcutTM with cutter extended.
Right: FlipcutTM with cutter retracted.
■ Cutter flips open to machine back spotface or back chamfer; flips back to closed
position for tool withdrawal. Can also be used for cutting front chamfers. No refixturing or repositioning of workpiece required.
■ Right-hand rotation opens cutter; left-hand rotation (spindle reversal) closes cutter.
■ Unique tool design: over-center cam action initiates positive mechanical closure
of the cutter, aided by centrifugal force, for superior tool performance.
■ Brazed carbide cutter construction. Cutter is rigidly supported for enhanced accuracy and long tool life.
■ Both cutter and arbor are designed for rugged use and long life.
■ Shear angle on cutter directs chips away from arbor pocket for controlled chip evacuation.
■ Standard tools in the inch program are available in .031 inch increments, with nominal sizes from .281 to 1.344
inches. Standard tools in the metric program are available in 0.5mm increments for hole sizes from 7.00 to
10.00mm, and in 1mm increments in hole sizes from 10.00 to 34.00mm.

Flipcut design features and options
Left: Standard cutter designed for back-spotfacing and front-chamfering.
Right: Standard cutter designed for back- and front-chamfering.
The FlipcutTM tool is designed to perform back-spotfacing or back-chamfering operations in one set-up. The cutter extends, with right-hand rotation of the tool, to cut the back spotface or back chamfer. Left-hand spindle rotation
initiates positive mechanical closure of the cutter; the closing action is assisted by centrifugal force. When the cutter is fully enclosed within the arbor pocket, the tool can be easily withdrawn from the bore.
The FlipcutTM tool is designed for rugged use on all types of plant equipment and in all kinds of manufacturing environments. Tools for hole sizes from .312 inch and above (inch program) and tools for hole sizes from 8.00mm and
above (metric program) have internal coolant capability.
FlipcutTM cutters are a brazed carbide design. Steel body absorbs shock. The brazed carbide FlipcutTM cutting edge
dissipates heat, for outstanding cutting performance.
Two standard cutters are available from stock:
■ Cutter designed for back-spotfacing and front-chamfering operations.
■ Cutter designed for back- and front-chamfering operations.
Other cutter designs are available upon request to suit other applications; contact our sales department and
request a quotation.

Operation
How it works
Flipcut™
NOTE: The tool operation sequence shown depicts
the tool with a standard cutter machining a back
spotface and a front chamfer in one set-up. Tool
operation is similar when using a standard cutter to
machine back and front chamfers.
1. The front chamfer is machined upon entry into the bore, using right hand
rotation (clockwise) of the machine spindle at the appropriate speed (refer to chart on
page 10), and .002 IPR (0.05mm/rev).
2. Left hand rotation (counterclockwise) at a maximum of .008 IPR (0.20mm/rev)
will effect mechanical closure of the cutter (aided by centrifugal force) so that the
tool can feed through the bore.
3. The back spotface is machined, using right hand rotation (clockwise) at
the appropriate speed (refer to chart on page 10), and .002 IPR (0.05 mm/rev).
4. Left hand rotation (counterclockwise) at a maximum of .008 IPR (0.20mm/rev)
will close the cutter so that the tool can be retracted from the bore.

Operation
Flipcut™
Operating guidelines
■ Always ensure that the cutter rotates freely in the arbor and that no end float can be detected. This can
be accomplished by adjusting the retaining screw (see photo below) until the cutter binds, then backing
off approximately 5 degrees. Using the locking screw, lock the retaining screw at this position.
■ Ensure that the spindle speed is sufficient to allow the cutter to open.
■ After the cut has been completed, and the tool withdrawn from the hole, make sure that enough coolant
is supplied to the end of the tool to flush away any remaining chips that might prevent the tool from
opening and closing freely in subsequent operations.
■ NEVER run the tool without coolant.
■ The tool cannot be used in a lathe with a static turret, since it must be rotated in order for the cutter to
extend and retract. The tool may only be used in a live spindle in lathe applications.
■ After completing the cut, always feed the tool off the part before stopping the spindle and reversing
for withdrawal.
NOTE: In some cases, the cutter may not close fully into the arbor when the spindle is reversed. This
should be considered as normal; the cutter will close fully as it passes back through the bore on the
return stroke. The retraction feed should be the same as the machining feed until the cutter is fully
closed and sheltered by the arbor; then rapid feed may be introduced.
To ensure that the cutter
rotates freely in the arbor,
with no end float, adjust the
retaining screw until the cutter binds, then back off
Retaining screw
approximately 5 degrees.
Use the locking screw to
lock the retaining screw at
this position.

Speeds and feeds
NOTE: For horizontal applications,
the tool should be run at two times
the recommended speed.

*Feed rate is the maximum value. When feeding the tool through the hole, prior to the
back-spotfacing operation, use reverse spindle rotation and .008 IPR (0.20 mm/rev)
maximum feed rate.
Coolant
Coolant flow is necessary and should be directed to the arbor pocket and cutting edge to lubricate
and flush chips away. Straight cutting oil, water soluble, or synthetic coolant can be used. The
coolant should be clean and have good lubricity.
Cycle
The tool must be able to rotate in both clockwise and counterclockwise directions. The tool should
run in counterclockwise rotation at the recommended speed and should feed in and out of the bore
at .008 IPR (0.20 mm/rev) maximum.
The cutter should be clear of the part when changing the direction of rotation.
Maintenance
The FlipcutTM tool should be inspected periodically for cutter axial movement, and the retaining screw
adjusted accordingly. The tool should also be inspected periodically for wear, and the cutter changed or
sharpened when necessary. The retaining screw should be inspected closely for wear or damage and
replaced if necessary.

Operation
Flipcut™
Cutter installation and setting
When the cutter is worn, loosen the locking screw (refer to the drawing below). Remove both locking screw
and pad. Loosen the retaining screw and remove the worn cutter. The cutter may be reground (see page
12, “Cutter Regrinding”) or replaced.
Clean all components thoroughly and apply light lubricating oil to each part for assembly.
Referring to diagram below…
1I Place and hold (2) spacers at the front and rear barrel diameter of the cutter while assembling into
the slot on the arbor.
2 I With cutter and spacers in place, insert retaining screw through the threaded hole in the end
of the arbor and then through the first spacer, the hole through the cutter, the second spacer,
and into the hole at the furthest end of the arbor slot.
3I When all components are aligned and positioned correctly thread the retaining screw into the
threaded hole in the end of the arbor until it makes contact with the spacer and the cutter goes
tight. The cutter should NOT pivot freely at this point.
4I Assemble the pad and locking screw into the threaded hole in the front outside diameter
of the arbor.
5I Tighten the locking screw lightly.
6I Unscrew the retaining screw very slightly until the cutter freely hinges between the fully open
and fully closed positions.
7I Check that the axial movement in the cutter is at the minimum but still allowing free hinging movement of the cutter. Measured axial gap should be 0.005 to 0.010 inches, (0.013 to 0.025mm).
8I When satisfied that the cutter assembly is correct, tighten the locking screw.
