CoaƟngs, Cuƫng Materials, and Dimple Indicators

CoaƟng InformaƟon

Uncoated Ideal for nonferrous applicaƟons.

TiN (N) Ideal for general purpose applicaƟons.

TiAlN (A) Provides higher heat resistance to improve tool life.

TiCN (C) Provides improved surface f inish.

Alcrona (K) Provides excellent wear resistance and can help increase cuƫng speeds.

Hardcut (H) Ideal for cast iron and hardened steel applicaƟons.

R CoaƟng (R) Improved tool life in cast iron materials.

T CoaƟng (T) OpƟmized tool life in Ɵtanium and very hard materials.

Cuƫng Material InformaƟon Material Indicator

Details

A fine-grain carbide suitable for all convenƟonal reaming applicaƟons. Recommended where rigidity is not excellent and speeds must be reduced.
