11 Degree 32mm Button Tapered Drill Bit Tungsten Carbide For Mine Drilling

Product Specification

11 Degree 32mm Button Tapered Drill Bit Tungsten Carbide For Mine Drilling

Tapered drill bits are Ideal for short hole drill & blast, as well as roof bolting applications, our hand-held system is comprised of premium alloy tapered hexagonal drill steels ranging from 0.5 m up to 7.9 m in length, and complimented by a complete range of reamers, blade and button bits.

Feature of the taper button bit:

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.

We can design and manufacture according to customers' samples or drawings of the Bit Dia., No. of air / water holes, carbide button shape and the face shape. Our button bit is made with high quality of best quality alloy steel bar and tungsten carbides, through heat treatment so that it can withstand the toughest rock drilling demands, and transmit intensive impact energy into the rock with the least possible loss of energy. Comparing with tapered chisel bits and tapered cross bits, button bits has higher technology, much longer primary drilling time and higher drilling efficiency. According to the tungsten carbideinsert, tapered button bits can be divided into the types of hemispherical, conical andparabolic button, etc.

Advantage of our taper button bit:

The tapered drill bits with diameter 32mm to 36mm 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.

Cemented carbide tapered button bit was 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. 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.

Our products were produced by the most advanced production lines to be the most cost performance rock drilling tools which carry at least 80% of the perfomance compared with their counterparts e.g Atlas Copco or Sandivik but being sold at much lower prices.

Parameter of the taper button bit:

1.Tapered chisel bit

Widely used in drilling holes with depth less than 5 meters and diameter ranged in 20-45 mm by light-duty rock drill, like Y6.

2.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.

3.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.
