Bit Breakers
Black Diamond Drilling Rotary Bit Breakers are specialty tools used for safely removing Rotary bits from the drill string. They’re particularly important in preventing injuries, avoiding damage to the threads, and improving efficiency and safety during bit changes.
Key Functions:
- Secures the bit to prevent movement while torque is applied.
- Prevents thread damage during make-up or breakout of bits.
- Improves safety by keeping the bit stable during handling.
Design Features:
- Custom sized to fit specific rotary bit sizes.
- Manufactured from hardened steel for maximum durability.
- Can be mounted to the floor of the drill rig.
