Three Kind Of Bit Face And Two Kind Of Button Shapes Are Available
Flat Face
Concave Face
Convex Face
Spherical Button
Ballistic Button
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.
We can also supply other size bits with different shanks. If you need more information, please contact our sales for details.
