Parameter specification of carbide twist drill:

Product introduction:

The cutting edge of carbide twist drill adopts three combined cutting edge structures. Each cutting edge only bears about 1 / 3 of the workload in the cutting process. In addition, there are cutting tools on the inside of each cutting edge. Therefore, the chip removal can be very smooth. In addition, due to the characteristic that each edge bears part of the cutting work, the hole drill is not easy to produce the phenomenon of edge collapse. The hollow drill can carry out high-precision and high-speed perforation on a 50mm thick steel plate, and can also drill cross overlapping holes. The three combined edge structure, unequal pitch division and special cemented carbide blade used in the edge are the crystallization of unique technology, So that the hole drill is not easy to produce the phenomenon of edge collapse, hollow bit with special core bit machine, with the characteristics of high efficiency and low cost.
