The tapered drill bits with diameter32mm 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.
With new manufacturing techniques, our cemented carbide has gained greater density and a more homogenous structure. Toughness has been increased without compromising. The exceedingly high wear resistance-making the material stronger without sacrificing its hardness. The gauge buttons of a drill bits are exposed to axial forces. Our former cemented carbides have always been able to handle that type of load with minimum risk of breakage. When the bits wears, the load angle changes and the risk for button breakage increases. The newly developed cemented carbide has significantly higher resistance to that type failure.
Tapered equipment is a 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”)
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.K.K.D. Limited 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 from spinning.
4.• Suitable for small hole range.
• Widely used in Dimensional Stone Quarrying Industry.
• Widely used in Underground Mining Industry.
