1) Precautions when Mounting When using the serrated R indexable inserts, mount them so that the serrated grooves alternate as shown in the image on the left. 2) Precautions for Cutting Conditions A s 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 = 0.008"/t With all regular blades: Feed Rate per Tooth 0.008 IPT With serrated types: Feed Rate per Tooth 0.016 IPT Using inserts incorrectly may damage tools.
