GCMN440R



●Ultra-fine Cemented Carbide

●Suitable for High Temperature Alloy and Titanium Alloys machining

●Rough, Semi-Finish and Finish processing

●4F, Radius, X coating, Unequal indexing, Multiple helix, Double Core design

●Excellent tools for Aerospace industry & Power generation. Neck design increases cutting length, double core design reduces tool deflection when finishing and improves tool rigidity.

●Recommend Application: Rough and Semi-Finish processing for Titanium Alloy
