ST68 4-6 Inch Spherical Bench Long Hole Tungsten Carbide Rock Drill Bit

Description

This type of bit is well known for its wear resistance on soft to medium-hard rock formations (between 55 Mpa to 165 Mpa compressive strength). Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture. Recommended for eliminating hole deviation.

The threaded drill bit are equipped with the hydraulic drilling jumbo and used for crush rock ,and it is widely used in tunnel construction, large scale mine(open and underground )and large section tunnel advance in metal mine.
Our threaded button bit is made by best quality alloy steel bar and tungsten carbide ,through heat treatment like Atlas, it includes R25,R28,R32,R35,R38,T45,T51,ST58,HT60,ST68 and so on. And the head diameter range from 32mm to 127mm.
