Features: - Large core design, smooth chip removal, increase tool rigidity, not easy to missing corners. - Suitable for fine-grained grinding wheel processing, reducing surface grinding wheel marks, more uniform coating treatment, and longer service life. - Relief angle design, reinforced triangular end face effectively improves the strength of the cutting edge to prevent cutting edge chipping. - Double ligament/35°helix angle, high rigidity and abrasion resistance, are good for low-speed and large-cutting, and reduce the burrs of the workpiece during processing and it is not easy to stick to the tool. - The cutting edge is passivated, and it is not easy to have burrs and cracks when enlarged without micro defects. Suitable for: - 2 Flute, cutting grooving is given priority to, 4 edge to side milling and face milling is given priority to. Suggest cutting HRC45 -within the steel material. - Suitable processing material: carbon steel, alloy steel, tool steel, hardened and tempered steel and steel parts hrc40-below. Safety instructions: 1. The bladed product is not use for people under 18 years. 2. The item is only use for industrial cutting  not hazardous article. Package Included: 1 Pc × Milling Cutter
