R25 Tungsten Carbide Rock Drilling Bits Thread Button Bits
R25 R28 R32 R38 button bit threaded drill bits granite rock
drilling thread button bits are widely used in all kinds of mining,
drilling, quarrying, engineering, construction, water well
drilling, oil exploring industries etc. The 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.

R25 type of bit is well known for its high wear resistance on
medium-hard to hard abrasive rock formations (between 200 Mpa to
260 Mpa compressive strength).
Featuring spherical tungsten carbide inserts that are known to have
strong configuration against carbide fracture.
The bit face design is ideal for medium-hard to hard abrasive rock
Applications
Used in small hole drilling.
