Caution when using Serrated R Type Inserts

1) Installation Precautions When using R type serrated indexable inserts, attach them so the serrated grooves alternate as shown in the image to the left.

2) Cutting Condition Precautions When set up as shown in the image to the left, the feed rate per tooth is doubled compared to that when attaching the same-shaped inserts on all teeth. This means that feed adjustments should be made so the upper feed limit is as shown below.

fz = 0.010 IPT Example: Use at fz = 0.008 IPT Feed when all teeth are normal Feed when serrated 0.016 IPT

Any incorrect use of insert may damage tools.
