TECH TIP: C(K) Chamfer Lead
A C/K Chamfer lead is the same length as the C chamfer lead in that it incorporates 2 – 3 threads into the lead
length. As an optional standard this chamfer form is found on semi-bottoming taps with a 40 degree R.H. helix. After
complete production of the tap (including hard coating) with the C chamfer form – there is an additional flute grind
through the cutting chamfer at approximately a 20 degree helix. This chamfer will show its best results when used in
moderately tough materials that tend to produce long chips. The “helix correction” helps to cause an immediate irregular chip flow as the chip formation is starting. This irregular chip flow helps to break the chip and allow it to flow
more freely up the flute. This geometry is very useful in applications where “birdnesting” is a common problem.

TECH TIP: Oversized taps
Oversized Taps are taps that are typically +0.003”/+0.005” larger than standard pitch diameter. An
H7 thread limit tap is +0.003” oversize from the basic pitch diameter while an H11 thread limit tap
is +0.005” oversize. Typically, oversized taps are used for threading parts that will be subsequently
plated or heat treated after tapping.

TECH TIP: Heli-Coil STI Taps
An STI Tap thread tap is designed to create an oversized
hole so it can accommodate the required Heli-Coil insert.
Screw Thread Inserts are helically formed coils of diamondshaped stainless steel or phosphorous bronze wire that
screw into a threaded hole to form a mating internal thread.
Screw thread inserts are a convenient way of repairing
stripped out threads and are also used to provide stronger
threads in soft materials than what can be obtained by
directly tapping the base material. Aluminum, zinc die cast,
magnesium and even wood are some materials an STI may
be used in.

Red ring taps for tough materials
Why a 15° helix vs a 40° helix?
When tapping high tensile steels or tougher alloys, using a tap with a lower helix
angle can sometimes improve tool life.
Tapping of high tensile materials typically produces high amounts of torque on
a tool. It is advantageous to note that when the needed thread depth is 1.5 x
diameter or less - a 15° helix tool will withstand higher torque than a 40° helix
while still pulling chips from the hole efficiently.

High tensile and some high alloy steels can be difficult to tap. Guhring’s red ring
offering provides you with tools that are designed with these materials in mind.
Both a thicker core diameter and a lower rake angle add strength for these
manufacturing applications.

TECH TIP: Type D Form
A type D chamfer form has a 3.5 - 5 thread chamfer lead. This chamfer can be used in both through
holes and in blind holes when the tap drill depth permits this chamfer length. This is especially useful
when tapping harder materials due to the extended chamfer length which distributes the thread
cutting process over more cutting edges. The D chamfer form is usually found on rigid, straight fluted
tap designs.

Thread milling cutters by
Features and Benefits:
Sub-micro grain carbide substrate
Longer tool life with tighter tolerances
Coming soon Watch for our
new brochure!
More cost-effective than indexable thread mills
PVD TiCN coating standard on many series
Extends tool life by providing heat and wear resistance
Helical flute design reduces chatter
The same carbide thread mill can produce
- Right or left hand threads
- Single or multiple thread leads
- Internal or external threads
Countersink style thread mills eliminate secondary operations
Coolant-fed style thread mills
For improved chip evacuation and better surface finish
Drill & thread mill styles combine drill and threading into one tool
