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:
