Product Description

HIP Finished Ground Carbide Spherical Button Bits Wear Resistance Button Bits

The spherical button is the most common shape utilized in DTH Bits. This type of shape is the strongest and most resistant to breakage. The domed shape provides excellent penetration in medium rock, hard rock, and hard rock broken formations, in all types of drilling.

Advantages:

HIP Sintering.
Excellent powder quality
Great performance of wear-resistance
Full range of button bits

Our carbide button bits range:

Rectangular and Flat Mining Bits
Parabolic Buttons
Wedge Buttons
Conical Buttons
Spherical Buttons
