6*6*19*60 represents: 6mm blade diameter*6mm shank diameter*19mm blade length*60mm overall length. Introduce it, thank you.

Recommendation: 4 blades for flat corners, 3 blades for aluminum products, 2 blades for keyways

Compared with standard milling cutters, this type of milling cutter has the following characteristics: simple, bright, unique, novel, and distinct in appearance; geometric accuracy is increased by 40% than standard products, and it is recommended for rough milling, semi-finishing milling, and suitable for finishing milling; Improve the smoothness of the front and rear corners to make the cutting edge sharp and chip removal brisk. The width of the relief angle is increased by 15%. Improved strength, stability and reliability; through unique processing, the service life is twice that of standard milling cutters, and it has a high cost performance. It can be used not only for general equipment in traditional milling methods, but also for numerical control equipment.

M2Al is a kind of cobalt-free super-hard high-speed steel. Vacuum heating promotes abnormal grain growth. Filling with inert gas for vacuum heating can increase the heating speed, hinder the formation of abnormally large grains, and improve the strength and toughness of M2Al steel. The most important factor affecting the strength and toughness of M2Al steel is not the size of the mixed crystal and austenite grain size, but the shape and distribution of carbides in the steel. In order to take advantage of the superhardness of M2Al steel, the vacuum quenching temperature can be increased to make its hardness above 66HRC.
