Rock Drill Blast Hole Drilling Tool Tapered Drill Rod For Mining 500 ~ 8000mm Length
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.
Tapered drill rod,also called taper rod, tapered drill steels, This provides a hexagonal chuck section to provide leverage for the rotation chuck bushing. It usually has a forged collar to maintain the proper shank striking face position in the rock drill, and a tapered bit end. Tapered steel lengths— available from 0.6 mto 3.6 m in length—are measured from the collar to the bit end.
