High Quality GT60 92mm Tungsten Carbide Drill Bits Rock Drill Bits
Hammer Drill Bits for Rock
KSQ rock drilling thread button bits are widely used in all kinds
of mining, drilling, quarrying, engineering, construction, water
well drilling, oil exploring industries etc.
Our thread button bits are made with high quality of best quality
alloy steel bar and tungsten carbides with superior wear resistance
and impact toughness superior, through heat treatment so that it
can withstand the toughest rock drilling demands, and transmit
intensive impact energy into the rock with the least possible loss
of energy.
Features:
Thread connection: R25, R28, R32, R38, T38, T45, T51, ST58, GT60
and ST68.
Carbide profile: Spherical, ballistic and parabolic.
Bit Faces: flat, concave, convex and drop-center, uniface.
Bits Diameters: 33mm-127mm
Bit body: standard and retrac
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.

Product Advantage:
1. Widely used drifting and tunneling
2. Bit face design is ideal for soft to medium rock formations
3. With retrac wings to help guide the bit in and out of the hole
4. Effective in straight hole drilling
