The skill of improving the service life of cemented carbide drill

During the production and manufacture of cemented Carbide drill , the main cutting edge of the bit will produce many burrs, so the burrs are fine. Under a hundred times microscope, the cutting edge of the bit will be serrated. If not removed, it is easy to produce the phenomenon of jumping edge falling off in the drilling work, and then the cutting edge begins to fall off. This gap will aggravate the wear during the cutting and seriously reduce the service life of the tool. Now there is a perfect way to solve this problem, that is to passivate the Carbide drill  . The passivation of the main cutting edge makes the cutting edge form an arc shape, reduces the jumping edge of the drill bit, and improves the surface quality of the workpiece after drilling.

钝化处理也叫强化处理，硬质合金钻头经过这种工艺后会使硬质合金钻头前刃口形成一个非常小的R圆弧，使切削阻力分散，并能消除刃口和韧带上一些细微锯齿状，从而增强了刃口的刚性。

Passivation treatment is also called strengthening treatment. After this process, the front edge of the cemented carbide bit will form a very small R arc, which will disperse the cutting resistance and eliminate some fine serrations on the edge and ligament, thus enhancing the rigidity of the edge.
