Tungsten Carbide Tapered Chisel Drill Bit , Hardened Steel Drill Bits
Tungsten Carbide Tapered Chisel Drill Bit , Hardened Steel Drill Bits
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.
• Suitable for small hole range
• Widely used in Dimensional Stone Quarrying Industry
• Widely used in Underground Mining Industry
