Tapered drill equipment also provides a hexagonal chuck section to provide leverage for the rotation chuck bushing, which usually also has a forged collar to maintain the proper shank striking face position in the rock drill, and match a tapered bit at the socket end. Holes are typically drilled in 0.6 m increments to accommodate the air-leg feed length.

Tapered equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. 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
