Product advantages
According to different materials to be processed, choose different materials and coatings, can improve the durability and accuracy of the tool, better control the tool cost
The processing of the drill point is very important, especially the processing of the cross edge, which is related to the service life of the tool and the accuracy of the drilling! Our 20 years of cutter design and manufacturing experience, more targeted to do a good job of each type of drill
The Angle and finish of the spiral groove are also very important, and with high quality coating, the processing efficiency of customers can be greatly improved
