This type of bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations (between 200 Mpa to 260 Mpa compressive strength). Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture. Used in drifting and tunneling.
Spherical Button Characteristics:
1. Universal button
2. Good wear resistance
3. Best suited for hard ground
4. 27000-48000PSI(180 to 320Mpa)
5. Suited for abrasive to very abrasive drilling conditions
Ballistic Button Characteristics:
1. Fast Penetration
2. Best suited for soft rock
3. 10000-20000PSI(70 to 140Mpa)
4. Suited for non-abrasive drilling conditions
Application:
1. Underground mining
2. Tunneling
3. In granite and marble quarry
4. Gold Mine
5. Dimensional Stone Industry
