ITEM NAME:7-piece Set of Point Drills Bits High Speed Steel Positioning Drills Bits Description: The 90-degree straight shank titanium-plated centering drill has the characteristics of high temperature resistance and wear resistance. The positioning and chamfering are completed at one time, and the drilled hole is really straight, not easy to collapse, and the life is increased. Coating Description: TiN coating can strengthen the surface hardness of the drill bit, improve the processing precision and improve the surface quality of the workpiece. The friction coefficient with the iron-based material is small, the anti-bonding performance is good, the friction and cutting temperature are effectively reduced, the material of the cutting steel and the easy-to-stick knife is reduced, the surface roughness of the processing is reduced, and the cutting speed is improved. In addition, the TiN coating is also resistant to chipping and thermal shock resistance, which is suitable for high speed cutting.
