Hot Sale 4 Flushing Holes Button Bit T51 Drop Center Thread Drill
Bit for Mining
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.
