89mm Diameter T51 Thread Retrac Button Bits
Tungsten carbide rock drill bit engineered for mining and tunneling applications in medium-hard to hard abrasive rock formations.
Product Overview
The Thread Button Bit is engineered for superior performance in medium-hard to hard abrasive rock formations with compressive strengths ranging from 200 MPa to 260 MPa. Featuring spherical tungsten carbide inserts, this bit delivers excellent resistance to carbide fracture, ensuring longer service life and reduced downtime in demanding drilling environments.
Key Applications
  • Underground mining and surface mining
  • Long hole drilling
  • Bench mining and production mining
  • Rock types: Granite, Basalt, Limestone, and other hard formations
Performance Features
