Short Skirt Tapered Drill Bit 12 Degree / 11 Degree For Hammer Rock Drilling

Product Specification

Tapered Drill Bit 12 degree 11 degree Button Bit Hex 22 Hex 25 For Hammer Rock Drilling
 
Our Tapered drill bits are made by high quality alloy steel bar and tungsten carbides. Through heat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks. Besides, we can design customized tapered button drill bits according to different drilling environment,applicable to drill soft rock, loose-medium rock and hard rock.
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.
Our Bits carry at least 80% of the perfomance compared with their counterparts e.g Atlas Copco or Sandivik but sold at much lower prices.

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 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.
