Low Cutting Resistance Chipbreaker GF Type                                                                      Chip control with point contact

Reduces chip control problems
The GF type chipbreaker is added to the current wide

selection of chipbreakers to improve chip control un-

der various conditions.

Reduces chattering during cutting
Ideal for machining using low-powered equipment
such as small lathes

Reduces adhesion to tools and achieves long tool
life in machining of stainless steel, etc.

Achieves excellent chip control and reduced cutting resistance due                                                                               Sharp cutting edge design     Grooving &
