sainsmart Genmitsu 10pcs Nano Blue coat end mill cnc Router bits

Spiral by SainSmart. Details:SPECIFICATIONS Shank Diameter: 3.175mm Cutting Edge Length: 12mm Overall Length: 37mm Cutting Edge Diameter: 0.8-3.0mm; 10Pcs; Innovative Nano Blue Coat Chemical Composition: Ni-La203 Physical Characteristics: 1. Enhance the hardness of the bits. 2. Reduce the frictional resistance coefficient of the bits at high speed to improve the smoothness of the machined surface. 3. Increase the heat dissipation performance of the bits to avoid the influence of the crystal structure change due to excessive temperature. 4. Reduce the phenomenon of chipping of the cutting edge. Enhance the elasticity of the bits. The impurities of the workpiece can be elastically skipped to avoid damage to the cutting edge. 5. Extend service life. 6. Since the carbide bit has high hardness and is relatively brittle, the machine speed range should be controlled during use. WHAT’S INCLUDED?
