Flat Face
Application: Hard and abrasive rock formation.
Typical formation: Granite, hard limestone, basalt.

Concave Face
Application: Medium hard to hard formations. Less abrasive, fractured formations. Excellent control for hole deviation.
Typical formation: Granite, hard limestone, basalt.

Convex Face
Application: Soft to medium hard rock. Non abrasive formation. High penetration rate.
Typical formation: Limestone, hard limestone, shale.

DTH BIT Features

1. Excellent insetting technology ensures that the carbides will not drop out from the bit body.

2. Advanced heat treatment equipment and technology to ensure the stability of the bit body performance.

3. Special bit surface design, structure design and specific processing technology are adopted to ensure the service life of DTH bit for different rock formation.
