11 Degree Tapered Button Bits Small Hole Drilling Tools Taper Drill Bits 32-41mm Work with Hand Held Work Drills
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.
