Rock Bits Tungsten Carbide Chisel Drill Bit is generally used to drill holes within diameter of 50mm in middle rock by light-duty drills, Like Y6, Y10, Y24. We have different taper degree according to customers’ request. Bit diameters varies from 20mm to 60mm.
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.
