hand held jackhammer button bits and drill rods

We offer high quality of tapered button bits & tapered drilling equipments, these tapered drilling button bits are made with high quality of raw material through special heat treatment, various type suitable for afferent work site. The diameter of tapered bits is from 28mm to 43mm with 4 6 7 11 12 taper degree. The deliver capacity are very strong and can completely meet customers' requirements on th design.

Integral drill rod has the advantages of eliminating the energy loss at the junctions of the taper drilling tools, resulting in a higher efficiency and avoiding the lose of taper drilling bits.. All the advantages make this drilling steels not only apply to the excavate project, but also the outdoor-drilling downwards, furthermore, integral drill rod extends its application range from that of the taper drill rods to the scope of secondary rock breaking of pick rods.

Taper drill rod is used for rock drilling, blasting holes and other drilling works in the quarries, coal mines, traffic and other contractions. It works with taper drill bits and has different length for various applications, our taper drill rods come in a variety of taper angles, generally, the light duty rock drill usually use 7 taper or smaller taper angle, the heavy duty rock drill mainly use 11,12 taper angle. And the basic theory is that taper drill rods and taper drill bits must be in the same tapered degree. We provide tapered rods in a full range of shank configurations and steel hex diameters for hand-held pneumatic drilling needs. Taper rock drill rod must together used with tapered drill bits, chisel bits, cross bits and button bits.
