H22 H25 Tapered Drill Rod Steel Tapered Rod With 108mm 159mm Shank 7 11 12 Degree

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.

Applications
1 Suitable for small hole range

2 Widely used in Dimensional Stone Quarrying Industry
3 Widely used in Underground Mining Industry

Why choose our Rock drill tools?

1.Tapered rock drill rod connect with button bits perfectly for drilling holes
2.Stable and mature welding technology ensure high quality of bits
3.Accurate dimension of taper degree perfectly matches the button bits
4.work reliable and very cost-effective
5. Rod bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment

Our 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.
