Laydown Threading
Insert Selection Guide
Step 3 • Choose Insert for Application
• Select cresting inserts for fully controlled thread form including diameter.
• Cresting inserts eliminate the need for deburring and are optimised
for the best tool life at that pitch.
• Non-cresting partial profile inserts offer the flexibility
to cut a variety of thread pitches with one insert.
• Note insert size for toolholder selection.
See threading insert overview on page F42.
Step 4 • Select Appropriate Shim
Required Information:
• Thread form (TPI or pitch).
• Pitch diameter.
• Helix method (hand of tool, feed direction, hand of thread).
• Number of starts.

If recommended shim is different from shim supplied with toolholder, order shim separately.
NOTE: Optimise your threading operation by using the proper infeed angle and the recommended infeed values. See the Technical Section on pages F83–F105.
Also see detailed shim selection information on pages F104–F105.
