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.
12U/13U/15U Improved chip control makes tool life longer and better machining.
16X

Stable machinability in interrupted machining toughness.

Stable chip evacuation and machining in machining with high depth of cut.

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.
