Rock Drill Bits T38 89mm Threaded Rock Drilling Button Bits for Top
Hammer Drilling Rigs
Thread Button bits are made by alloy steel bar of quality and
tungsten carbides.
Through heat treatment, our drilling tools are tough enough to meet
rock drilling demands and have the least loss of energy while
drilling the rocks.
With the top quality of alloy steels imported from USA and the best
carbides made in China, we produce all retract threaded button bits
by hot press technology.
Thread size: R32, SSR32, R35, SSR35, R38, T38, T45, T51, SST58, SST68, SGT60.
Diameter: 51mm to 152mm.
Face tape: Flat front, Drop center front, Uni-face
How to choose the bit tooth type:
Spherical buttons: The height of exposed teeth is low, mainly used
in the very hard rock formation above F14, to improve wear
resistance, to prevent the situation of debris, it should take
lower drilling speed.
Ballistic buttons: It can expose more height of buttons, mainly
used in soft rock and ordinary rock below F12, with quicker
drilling speed, but encountered hard rock, very easily to happen
buttons debris phenomenon.
How to choose the face type:
