Functions and Features

These drill tools are mainly equipped on rock drilling equipment, well drilling equipment and oil field equipment.

Our taper drilling tools include taper drill bits and taper drill rod, and taper drill bits come into two types, taper button drill bits, and taper chisel drill bits.
They are widely used for rock drilling, blasting holes and other drill works in quarries, coal mines, rod and dam constructions and other similar projects.

Product Description

Generally, chisel bit is mainly useed for hard rock, cross bit and button bit are mainly used for fissural rock. It is mainly used for diging into mine laneway and blasting holes in all drilling works matched with the taper drill rod. For different rock, we choose the different alloy to extend the working life of the drill bits.
