Products Description
Tapered equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. Drillers choose
tapered chisel bits if the goal is to minimize hole deviation in small hole range drilling. Different taper sizes have different
characteristics when it comes to the “knock-off” index – the smaller angle will prevent the bit from spinning. Used in drifting and tunneling.
