Chipbreakers

Chipbreakers

Chipbreaker	Features	Application	Cuting Edge
15M	Shallow depth of cut with sharp edge. Longer tool life at high speed cutting due to low cutting force. Good finishing surface.
15V	Longer tool life due to minimizing chip contact and reducing cutting heat while machining.
25UL	High positive cutting edge reduces chip contact. Minimized temperature while machining ensures longer tool life. Stable machining with superior chip evacuation in high depth of cut.
10U/12U/13U/15U	Improved chip control makes tool life longer and better machining.
14K	Good chip control at finishing to light machining with low cutting force
15K	Excellent chip control in application with micro depth of cut and low feed. Low cutting load and super finishing surface. Excellent for both internal and extemal machining
14VI	Longer tool life due to minimizing chipcontact and reducing cutting heat whilemachining.
PY	Great combination of sharpness and toughness.Excellent chip control.
PC	Sharpest molded chipbreaker. Excellent chip control. Less tool pressure.
