T38 89mm Thread Rock Drill Button Bits Drilling Bits for Rock
Drilling and Mining
Material Description:
Thread button bits made with high quality of best quality alloy
steel bar and tungsten carbides, 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.
Application:
Threaded Drill Bits cover regular, retrac and reaming types. With
stronger button-fixing ability, longer service life, better
wear-resistance and impact-resistance performance, they are widely
used in tunneling, underground mining, open pit mining,anchoring
and other large-scale construction projects.
Main button bits diameters:
R32-45mm, R32-51, R32-64, R32-76, T38-64mm, T38-76mm, T38-89,
T38-102mm, T45-76mm, T45-89mm, T45-102mm, T51-89mm, T51-102mm,
