PDC anchor drill bits (family) - 25mm-450mm

Application:

It is mainly used to drill the bolt-mesh support hole and small diameter hole in the fields of mining, transportation, nonferrous metal and water-power engineering.

Name: PDC anchor drill bits with two wings (ordinary type)

Feature: Suitable for drilling in soft--medium hard rock formation (terrane). The service life of drilling is 10-30 times longer than normal alloy bits in the same rock formation (terrane). The efficiency can increases by more than 50%, non-diameter reduction, no need to repolish, reduce labor intensity effectively and save the work time.

Name: Strengthened PDC anchor drill bits with two wings

Feature: Suitable to drilling in hard rock formation(terrane). The blade is made of strengthened compact bits, which contains 150% diamond more than ordinary one, have high-strength gage protection ability and perfect abrasive resistance; moreover, high efficiency when drilling hard rocks.

Name: PDC anchor drill bits with three wings

Feature: It is applied to drill the hard rock. The plane layout of three blade wings has improved the stability of drill bits, further strengthened the gage protection ability, and the service life is 2-3 times longer than the ordinary drill bits with two wings. It is an ideal tool for drilling in the hard rock formation, and has perfect abrasive resistance performance.

Name: Spiral PDC anchor drill bits with two wings

Feature: The spiral guiding groove enables the drainage and cutting goes more smoothly, the king-size drill body ensures the pore diameter, and improves pore-forming quality effectively and saves working time.
