12° 30mm 40mm Industrial Drill Tapered Cross Bit For Stone

12° 30mm 40mm Industrial Drill Tapered cross Bit For Stone

Description

Tapered equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. Drillers choose tapered cross type 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.

• Suitable for small hole range
• Widely used in Dimensional Stone Quarrying Industry
• Widely used in Underground Mining Industry
