Tapered Button Bits

pic8.png

Taper bits, especially Tapered button bits are the most popular tapered drill bits with a wide selection of head diameters from 26mm to 48mm. With carbide buttons pressed on the bit skirts, tapered button bits have a good drilling performance and are excellent in longevity.

Applications

Taper drill bits are connected to taper drill rods for drilling duties, suitable for tunneling, construction, mining, quarrying, etc.

Dimensions
Parameters

Tapered Drill Rods

pic10.png

Tapered drill rod is a further development of the integral drill rods. It usually has a forged collar to maintain the proper shank striking face position in the rock drill.

​

With one side connected to rock drill and the other side connected with taper drill bit, the taper drill rod transmits power from rock drill to bit, drilling work is thus performed. Tapered drill rod is a further development of the integral drill rods. It usually has a forged collar to maintain the proper shank striking face position in the rock drill. Tapered drill rod effective lengths are measured from the collar to the bit end, which are usually from 0.6meter to 3.6 meters.

Applications

Drilling duties in tunneling, construction, mining, quarrying, etc.
