Shim Selection
If a thread pitch is large or a pitch diameter is small, a thread lead angle becomes
large and the effective clearance angle on the leading edge becomes small.
Ideally, threading inserts should be mounted so that the clearance angles on both
right and left sides become equal.
For this reason, it is necessary to select an appropriate shim for the thread pitch
and pitch diameter by consulting the table below.
Shim Selection Procedure
(1)
Choose either one from [RH/LH Thread] in the table.
(2)
See the rows below [Pitch] to find a pitch for a thread to produce.
(3)
Find the cell that shows a diameter of the thread in the column below [Effective Diameter].
(4)
Confirm a Cat. No. in the [Shim] row shown above the cell found in (3). If the shim that
is already in use has a different catalogue number, replace it with an appropriate one.
(Example)
When machining an M16×2.0 external right-hand thread, the effective
diameter is 14.701mm. In the table below, find [2.0] mm for a pitch and then
follow this row rightward to the cell of effective diameter of [11.4-17.4] mm.
The cell where the row of [External] meets the column of pitch diameter [11.4
- 17.4] mm shows [YE3-1P]. It is the right shim for machining this thread.

SSTE Type/SSTI Type holders are shipped with a shim for a lead angle of
1
=1.5° (SSTE Type: YE3, SSTI Type: YI3).
Shims for lead angles of
1
=-1.5°,-0.5°, 0.5°, 2.5°, 3.5°, and 4.5° are sold separately.
Shims are unnecessary for SSTI R1812M16 and SSTI R2016M16. (The holders are already provided with the standard holder inclination of 1.5°.)

Performs threading without machining thread ridges (Machined
surface from the previous process is left unworked.)
Enables machining of threads with different widths with the same
insert
Workpiece needs to be machined up to the major (or minor)
diameter in a process prior to threading.
Fine burrs are easily formed on edges of ridges
Enables machining works into shapes compliant with thread
standards
Enables thread machining only for those compliant with certain
standards or those with determined pitches
Needs to keep machining allowance of 0.1mm per side due to the
use of wiper edge for thread ridge nishing.

Wiper Edge
Infeed Method
The modified flank infeed is recommended for SSTE Type / SSTI Type.
This infeed method, which features reduced chip curl diameters and stable chip control, can also decrease chipping on trailing
edge that often occurs in radial infeed. (For modification angle, 1° is recommended.)

Often used in common tooling for a
work that has a thread at its top
end. In this type of tooling a
necking width indicated with an
arrow can be reduced since a
cutting edge point is placed closer
to the guide bush side.
Usually used when a thread is located
in the middle or at the back-end of a
work.
In this type of tooling a necking width
indicated with an arrow can be
reduced since a cutting edge point is
placed closer to the back turning side.

When a left hand holder is used, a sufficient cutting distance can be kept
since the cutting edge point separates from the guide bush.
For left hand holder, the meanings of A Type and B Type for the right
hand holder are switched with each other. (B means the guide bush side
while A means the back turning side.)

Use the inserts shown on the left with STHI Type holders.
Edge honing of inserts can be enlarged for threading using NIR2000
with pitch of 1.5mm or more, and using NIR3000 with pitch of 2.5mm
or more. Honing amount should be within threading tolerances.
All inserts are 3-cornered.
