Fast Penetration Taper Button Bits For Rock Tungsten Carbide Taper Drill Bit 


Tapered Drill bits are further development of the integral system where a comprehensive selection of bits can be used on the same rod. There are two standard hex rod sizes - 22mm or 25mm in diameter and up to 8000mm in length and a wide selection of bit designs for hole sizes 27-41mm (11/16" to 15/8").

Taper Drill Bit Is widely Used In Metallurgy Mine, Geological Exploration, Water Conservancy Construction, Electricity, Traffic, Tunnel, Quarry, National Defence Stone Project Etc.

Our Drills have been exporoted all over The World, Like Germany, Spain, Italy, Russia, Japan, India, Australia, Mexico, Colombia, Brazil,Chile, South Africa...Etc. and has very Good Reputation Worldwide!

Our are 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.

The 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.

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.

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.
