Description
Comparing with tapered chisel bits and tapered cross bits, button bits has higher technology, much longer primary drilling time and higher drilling efficiency.
According to the tungsten carbide insert, tapered button bits can be divided into the types of hemispherical, conical andparabolic button, etc.
Thread button drill bits are made by high quality alloy steel bar and tungsten carbides. Through heat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks. Besides, we can design customized thread button drill bits according to different drilling application, and custom drill bits are applicable to drill soft rock, loose-medium rock and hard rock.
Applications
Widely used in mines, quarries, earthworks and other engineering drilling blasting hole, guardrail hole,mountain reinforcement, anchorage and other engineering holes, geothermal exploration hole, Well bore and other fields.
