With top quality alloy steels and best quality tungsten carbides, we produce all retract threaded button bits by hot press technology.
Characteristics
1.Cutting edges makes it easy to remove bit in adverse hole conditions.
2.Retract wings help to guide the bit, reducing the hole deviation.
Application:
- This type of bit is well known for its wear resistance on medium-hard to hard rock formations
- Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture
