Gundrills, deep-drilling heads carry three-edged inserts

Iscar has introduced new gundrills and deep drilling heads in the 16- to 28-mm-dia. range that carry three-edged indexable inserts with chip splitters.

The TOGT inserts feature three chip splitting cutting edges, a positive-rake chipbreaker, and a wiper to help create the best possible surface quality. The new inserts, made from IC908, a PVD-coated grade, are available in five sizes.

The new drilling lines are:

DDD-EF-FT. These deep, double-tube drills with external four start thread carry the TOGT inserts and feature three chip splitting cutting edges and a wiper. Diameters are from 18.4 to 28 mm.

DSD-IF-FT. These deep, single-tube drills with internal single start thread carry the TOGT inserts and feature three chip splitting cutting edges and a wiper. Drills are available in diameters between 16 and 28 mm.
