tungsten carbide threaded drill bit for rock and soil projects
Thread drill bits are made byhigh quality alloy steel barandtungsten carbides.
Throughheat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks.
In addition, we can designcustomized thread button drill bitsaccording to different drilling application, and custom drill bits are applicable todrill soft rock, loose-medium rock and hard rock.
