threaded drill bits include general, retrac and reaming three
series, with stronger button-fixing ability, longer service life,
better wear-resistance and impact-resistance performance, widely
used in tunneling, underground mining, open pit mining, anchoring
and other large-scale construction projects.
Main Features
1. The threaded drill bit are equipped with the hydraulic drilling
jumbo and used for crush rock ,and it is widely used in tunnel
construction, large scale mine(open and underground )and large
section tunnel advance in metal mine.
2. Our threaded button bit is made by best quality alloy steel bar
and tungsten carbide ,through heat treatment like Atlas, it
includes R25,R28,R32,R35,R38,T45,T51,ST58,HT60,ST68 and so on. And
the head diameter range from 35mm to 127mm.
