Tapered steel rod work with taper drill bits which are usually hexagonal. When it comes to the small-hole drilling tools equipped with pneumatic & hydraulic rock drills.
Taper steel rod are the same as integral drill rods which have different length to fit different drilling applications in mining, quarrying, road building etc. Taper drill rods need tapered drill bits to work, such as tapered chisel bits, tapered cross bits and tapered button bits.
There are different taper angle ( 6 degree, 7 degree, 11 degree, 12 degree, etc.)on customers’ request. Taper drill rods and taper drill bits must be in the same tapered degree.
