Geometry
- The extra negative geometry produces a high working temperature which
anneals the tap
- Regrindable geometry.
- No cutting fluid is required −drill dry.

Hard-Cut drills are supplied as follows:
a) In 5 piece sets comprising a drill of each size.
Ordering example for 2 sets: 2 sets HC 23456
b) Drills can also be ordered individually with a minimum quantity of
3 pieces of each size.
Ordering example for 10 pieces of HC2 drills: 10 pieces HC2
Application
- Drills are primarily designed for removal of broken taps, hardened bolts
etc.
- Can also be used for drilling in other difficult materials e.g. chilled cast
irons, stellite and glass.
Use machines with a stable spindle.
- FMS (flexible machining system), M/C:s, NC and NC-lathes, CNC,
automatics, centre and turret lathes and milling machines.
SAFETY INFORMATION
Precautions when grinding and brazing of
cemented carbide, see page I3.
Operating procedure when drilling
1. Securely clamp the workpiece on
the machine table in a vice or
similar rigid work-holding fixture.
Centre the drill on the broken tap.
2. Centre drill in the uneven surface
of the fractured tap, with a larger,
more rigid drill than the one which
will eventually be used for drilling
out the tap.
3. Select the correct size of HardCut drill according to the list in the
table above. The recommended
spindle speeds are 1500-3500
rpm. Drill with a consistent, steady,
manual feed. Stop frequently to
clear chips from the hole.
4. Once the tap has been drilled out
it is a relatively simple matter to
remove the remain-ing parts of the
tap using a scriber or similar
pointed tool.
