T51 89mm Tungsten Carbide Thread Button Bits Rock Drilling Tools
Button 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.
• Widely used drifting and tunneling
• Bit face design is ideal for medium-hard to hard abrasive rock
