Edge Specification of SUMIBORON Inserts

SUMIBORON Insert and Edge Preparation

All SUMIBORON inserts are enhanced with the optimum cutting edge

preparation for the various grades and geometries (shown on the right).

This is to avoid cutting edge fracture caused by the heavy loads generated

during the machining of high hardness materials such as Hardened Steel.

As the pioneer of CBN tools "SUMIBORON," various selection of grades

and edge preparation combinations is our strong point for Hardened Steel

machining.
