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.
