Product Description
1.5 inch Tapered Button Drill Bit , 12 Degree 30mm 40mm Rock Drill Bits
Description
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.
