Which size do you need?
- Inscribed circle sets the maximum depth of cut. As a rule keep ap under about two thirds of the IC.
- Nose radius trades finish against strength. A larger radius gives better surface finish at the same feed and a stronger edge, but raises cutting force and cannot produce tight internal corners.
- Check the holder. The holder designation must carry the same shape letter and the same size digit as the insert.
