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.
