It is composed of steel drilling body and can be changed by the whole cemented carbide crown, compared with the welded cemented carbide bit, its machining accuracy is 82 and a half Jin, but because the crown can be changed, it can reduce the processing cost and improve the production rate of drilling. This kind of drill bit can obtain the accurate aperture size increment and has the self-centering function, is to the aperture machining precision is very high.
