HENGWANG Manufacture H22 Drill Bit for B22 Drill Pipe
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 from spinning.
