5 PCS 1/2 4 Flutes Square 45° Helix Carbide End Mill AlTiCrN Coated

  

General Usage : Applicable with copper, copper alloys, cast iron, steels, carbon steels, alloy steels, pre-hardened steels, hardened steels, and stainless steel materials. Solide Carbide : 10% Micrograin Carbide, HRC 48 AlTiCrN Coating : Aluminum Titanium Chromium Nitride (AlTiCrN)offering better heat resistance than TiAlN, TiN or TiCN coatings. It is able to provide high wear resistance, lubricity, exceptional oxidation resistance, extreme hardness, and excellent abrasive wear resistance. It has higher re liability in Dry operations, heat resistance, hard machining, and the resistance can be reduced. 4 Flute Cutter: It has uniqe geometry and strong cutting edge.

4 flute is great for speedy cutting. Ideal for planar, step, groove, forming surface while the 45 degree helix design can perform smooth surface finish, better chip removal control than those with lower helix degree. General purpose end mill : Roughing and Finishing Cut. We will respond to you within 24 hours and do our best to help you out!
