How To Choose Drills?

Jinan Supertime Technology Co.,Ltd | Updated: Jun 22, 2017

To drill holes 0-40mm in diameter, we can choose carbide drill, with good solidity and drilling performance, generally applied in high speed drilling equipment, in boiler, bridge, shipbuilding, wind power, nuclear power etc. In comparison with twist drill, efficiency is increased 3 times.

And sometimes when drilling holes it’s not necessary to cut off all the metal with chips and shaving. So the most economic way is to use trepanning drill, by driving drills into socket and turn the shank, round slots can be made by removing the metal in form of disk and leaves a hole on steel plates.


This method can reduce material waste and machine power consumption. When the sample is removed for performance testing, the trepanning drill is the unique tool which can’t be replaced by others.
