Product Name: JBWTL Titanium Coated Cobalt Point Drill

Material: high speed steel containing cobalt

This product is a 90-degree titanium-coated cobalt-containing straight shank centering drill with TiN coated on the surface. It has the characteristics of high temperature resistance and wear resistance. The positioning and chamfering can be completed at one time. The drilled hole has good straightness, is not easy to chip, and has a long life .

Coating description: TiN coating can strengthen the surface hardness of the drill bit, improve the processing accuracy, and improve the surface quality of the workpiece. The friction coefficient with iron-based materials is small, the anti-adhesive performance is good, and the friction and cutting temperature are effectively reduced. The cutting of steel and materials that are easy to stick to the knife reduces the surface roughness of the processing and increases the cutting speed. In addition, TiN coating has better chip resistance and thermal shock resistance, which is very suitable for high-speed cutting.

⊙Supplementary note: Even if the material is the same, the performance of the tool will be different due to the difference of the manufacturer, the quenching technology and the groove process.
