T38 76mm Tungsten Carbide Mining Tools Thread Rock Drill Button
Bits
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 Product Name: | different rock hardness drilling button bit | Description: | For different rock hardness mining,tunneling,quarrying button bit
