Ballistic :
Description:
This type of bit is well known for its high wear resistance from
soft to hard abrasive rock formations. Dedicated for use in low
power drifter. Featuring spherical tungsten carbide inserts that is
known to have strong configuration against carbide fracture.
Recommended for eliminating hole deviation. Used in benching and
long hole drilling.
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
Conical Button Characteristics:
1. Fast Penetration
2. Best suited for smaller diameter bits
3. Suited for non-abrasive drilling conditions
***Available on the request
