H22 Tapered Rock Drill Steel Rod tapered Hexagonal Hollow Steel for mining drilling in tunning
Tapered drill 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.

Hex22mm / Hex25mm Rock Tapered Drill Rod , Blast Hole Drilling Tapered Rod
Tapered equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. Different taper sizes have different characteristics when it comes to the “knock-off” index – the smaller angle will prevent the bit from spinning.
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. Steel grade: 95CrMo equivalent to SANDBAR 61.
6. Shank size: hex.22mm×108mm, hex.22mm×159mm.
hex.22mm×80mm, hex.25mm×108mm. hex.25mm×159mm.
7. Taper: 6, 7, 11, 12 degree etc.
8. With highly and strength of resistance on the bending, welding fixed.
9. Highly efficiency on production and steady quality.
10 It’s able to keep the hole straight and with long use time.
