Product advantages

Stainless steel is a relatively difficult material to process, need to choose a good material and coating, control the front corner of the tool and blade belt design, in order to better drill this material

The design of drill point is very important, can design arc after Angle drill point and cross drill point, according to the needs of different customers, the structure of the drill can be different

The Angle of spiral groove is also very important, can affect the iron filings! According to the needs of customers, it can also be made into double-edged belt structure, good stability
