Tungsten Carbide Tipped Drill Bits , T51 Mining and Stone 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
Button bit and Insert types
