Fundamentals of screw threads
Relationship between lead, lead angle and pitch
1. Lead is the axial distance a screw advances in one rotation. In single
start screw, the lead is equal to the pitch.
2. The inclination angle of a threaded groove is called lead angle. In screws
of the same diameter, the lead angle increases as the pitch increases.
3. The side face of a completed thread groove is called flank. The distance
between the crest and the root is called thread height.

Lead angle

Single and multi start thread
L
1. The single start thread has a single groove. Two start thread or three
start thread has two grooves or three grooves respectively.
2. When viewing the section of the multi start thread, the pitch is same as
that of the single start thread. The lead of the two start thread is twice the
pitch. The multi start thread is mainly used for trapezoidal threads.
P
Tolerance class of threads
Threading Tools
7
Tolerance classes of screw threads are expressed as follows:
Metric coarse external thread: 6h, 6g Metric coarse internal
thread: 5H, 6H
These classes are ranked with tolerances of thread diameter,
pitch, thread angle, etc. For fastening applications, 6H- and
6g-class (former JIS second class) threads, manufactured by
cutting or rolling, are generally used. 5H- and 4h-class threads
(former JIS first class) are generally finished by grinding.
For example, M8-6g means metric coarse external thread of
6g tolerance class.
TAC threading inserts
Difference between full-profile and partial-profile insert
Full-profile insert
In the full-profile insert, the major diameter of the thread is
finished by the profiled finishing edge as shown in Figure below.
Therefore, about 0.1 mm of finishing stock must be left on the
outer surface of the workpiece before threading. In trapezoidal
Partial-profile insert
threads, since slants of 15º to 30º are left on the crest of the
thread as shown in Figure below, these portions must be
finished later.
Burrless threads can be produced with the full-profile insert.

Shim replacement method
Compensation for the lead angle and tool relief angle
When the pitch is large or the screw diameter is small, the
lead angle becomes large and the effective relief angle on the
advance flank side β2 becomes small. In particular, this will
cause shorter life of the insert in the case of trapezoidal screw
with small flank angle. It is ideal without any interference for
the thread cutting insert to have an equal relief angle on both
right and left. Replace the shim so that the rake face of insert
faces the thread groove direction (that is, β = β3).

In other words, β1 = β2 when the thread lead angle is equal
to the compensation value. Namely, the relief angle of the
tool itself is equal to the effective relief angle. If the wrong
compensation value is used, β1 > β2. Namely, the effective
relief angle becomes smaller. Therefore, carry out compensation of the lead angle so that the following range is
obtained:

In the tables starting from page 7-30, the relationships between toolholders,
inserts, threads to be machined, and shims to be replaced are shown. In these
tables, the criteria are set as follows.
¡The minimum machining diameter.
¡The L/D ratio of the toolholder.
¡The lead angle of the thread.
¡Cutting conditions
Especially when machining near the minimum machining diameter, the
compensation for the lead angle should be done carefully.
Moreover, in threading, because chips generally can not be broken into small
pieces, the shank size should be selected in consideration of adequate
clearance (C1).

How to use the tables

rBy following the row to the right,
toolholders of
mark are usable, but less rigid because the shank diameter against the threading diameter is smaller than
those of

insert Cat.No. is 16IR15ISO.
tIn the case of M33 X 3 thread, the lead angle is 1°46′. By following the row to the right. x mark is found. This indicates that
the shim should be replaced to 2° type. For calculation of the lead angle, refer to page 7-27.

Because this thread standard is characterized with large pitch and small diameter, (that is a large lead angle) the standard inserts and toolholders can not
be used for machining this thread type. The application is limited to outside of the standard.
Note : The above tables show correspondence of internal toolholders at the time of setting clearance between thread and toolholder to 3 mm (1 mm in case of
SN type) and the finishing stock to 0.1 mm.

Note:
• When using the full-profile insert, set the total infeed amount by
taking the finish stock of .004 in. into account.
• Set the first infeed to 150 ~ 200% of nose R and do not allow it to
exceed .020 in.
• The infeed amount during the final pass must be a minimum of
.002 in. No zero cuts should be made. (Extra small infeed or zero
cutting of work hardened surfaces will reduce tool life.)
• The partial-profile insert or inside diameter insert has small nose R.
Reduce the infeed per pass and increase the no. of passes.
• Regarding standard infeed per passes and no. of passes, please
refer to our catalogue.
Infeed Methods for ST-type Tools
Infeed method
Straight infeed (radial infeed)
Features
• Most simple and usual method
Suitable for relatively small pitch threads of easily machinable material.
• Chip contact length on right and left is longer, causing chattering, with increased load on
the nose end.
• When the half included angle is not symmetrical to the right and left, infeeding in the
direction of 1/2 of the included angle will ensure equal machining with right and left
cutting edges.
• Suitable for large pitch threads or easy to tear materials. Effectively prevents chattering.
• Chips are discharged in one direction only. Satisfactory chip control.
• Edge on the right (with zero infeed) tends to be worn heavily.
Single edge infeed
(flank infeed)
• Suitable for large pitch threads or easy to tear materials. Effectively prevents chattering.
• Chips are discharged in one direction only. Satisfactory chip control.
Modified single-edge infeed
(flank infeed)
• Edge on the right performs some cutting, therefore
wear of this edge can thus be suppressed.
• Suitable for large pitch threads or easy to tear material. Effectively prevents chattering.
• Chips are discharged alternately in right and left directions, resulting possibly in
entanglement.
• Right and left edges are used alternately, ensuring uniform wear and extending tool life.
