1. With carbide buttons hot pressed on bits bodies, Tapered Button
Bits have a very good drilling performance and long life time.
Different diameters and taper degrees are available to suit
different applications in mining, quarrying etc. We can supply long
skirt and short skirt Tapered Button Bits.
2. Comparing with tapered chisel bits and tapered cross bits,
button bits has higher technology, much longer primary drilling
time and higher drilling efficiency, so that the button bit is
popular among the users.
3. Tapered equipment affords drillers the ability to change
drilling bits whilst still using the same drilling rod. Drillers
choose tapered button bits for faster drilling penetration rate.
Different taper sizes have different characteristics when it comes
to the “knock-off” index – the smaller angle will prevent the bit
4. Suitable for small hole range
• Widely used in Dimensional Stone Quarrying Industry
• Widely used in Underground Mining Industry
Widely used in mines, quarries, earthworks and other engineering
drilling blasting hole, guardrail hole,mountain reinforcement, anchorage and other engineering holes,
geothermal exploration hole, Well bore and other fields.
1. The threaded drill bits are equiped with the hydraulic drilling
jumbo and used for crush rock, which are widely used in the tunnel
construction, large scale mine (open and underground) and large
section tunnel advance in metal mine.
2. New Diamond can make all kinds of threaded drill bits, that
include R25, R28, R32, R35, R38, T38, T45, T51,ST58, GT60, ST68 and
so on, and the head diameter range from 41mm to 152mm.
3. Our R&D team will develop the sharpest industry "teeth", the
most suitable bits for different application. The bits with sharp
buttons are suit for harrd and mid-hard rock, and have excellent
wear resistence and driving speed. The bits with round buttons are
extensively used in hard rock with high abrasion and impact
4. Our button bit is made of top quality steel and tungsten carbide
same with well-known brand in the world. For the technic, we take
“hot-insertion” processing procedure to insert the buttons into the
bit. Optimized designs improve the drilling efficiency. And
automatic production line ensure the quality stability of product.
Strict requirements of heat-treatment guarantee durability of the
