Usage:drilling in ore field,suitable even for harsh enviroment works;

Tapered drill bits are widely used in mining and quarrying, with the advantages of higher driving efficiency, long service life, better powder exhausting and easier bit back, which combine well anti-wear and anti-impact carbide butttons and high-performance steel together.

Premium designs and steel and premium tungsten carbide inserts, offers industry leading strength and penetration rates for more productivity, excellent straightness and hole clean quality, get max drilling performance for rock drill with long life to save up fuel cost rate.

Parameter of the taper button bit:

Cemented carbide tapered button bits are made from high quality cemented carbide, produced with advanced technology and equipment, having different types bits, such as tapered chisel bit, tapered cross bit and tapered button bit which connected with tapered drill rod well for drilling hole, inserting depth is 25-30mm, obtaining maximum drilling speed, keeping stable and lowering rock drill working parameters so that prevent single button under overload then cause the button broken or lost.

Tapered cross bit

Used under any rock drilling condition and mainly used for hard or very hard rock formation because of it's comprehensive adaptability. Compared with taper chisel bits, taper cross bits have a better drilling performance because of carbide tips on cross bits doubled.

Tapered Button Bits

Comparing with tapered chisel and 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 and parabolic button.

Cemented carbide tapered button bits widely used in gold mining, geological drilling, railway, highway, water conservancy and hydropower, tunnel working and granite and marble quarrying.
