Nicked R Type

1) Precautions when Mounting When using the serrated R type indexable inserts, mount them so that the serrated grooves alternate as shown in the image on the left. 2) Precautions for Cutting Conditions As these are mounted as in the image on the left, compared to mounting inserts of the same shape for all blades, the feed rate per tooth is doubled. Accordingly, f z = 0..010 IPT feed rate is set as the upper limit and can be adjusted for use. Ex.) For use with f z = 0.2mm/t With all regular blades: Feed Rate per Tooth 0.008 IPT With serrated types: Feed Rate per Tooth 0.016 IPT
