Product Description
Description
H22 Tapered rock drill steel rod is a further development of the integral drill rods. It usually has a forged collar to maintain the proper shank striking face position in the rock drill. Tapered drill rods effective lengths are measured from the collar to the bit end,which are usually from 0.6 meters to 3.6 meters.
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.

Performance
H22 Tapered rock drill steel rod has the following advantages
1. Excellent comprehensive mechanical properties
2. High connection strength and sealability
3. High fatigue strength and long fatigue life
4. Good flushing effect to ensure high drilling rate
5. With highly and strength of resistance on the bending, welding fixed.
6. Highly efficiency on production and steady quality.
7. It’s able to keep the hole straight and with long use time.
Application
H22 Tapered rock drill steel rod is mainly used in rock drilling, blasting holes, and drilling works in the quarries, metallic mines, tunneling and constructions.
