Coal Mine Tungsten Carbide Retrack Bit Button Drill Bit For Mining With High Speed
With carbide buttons hot pressed on bits bodies, Tapered button drill 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 taper button bits.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.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.
