Steel Tapered Rock Drill Rods , Durable H25 Hex Tapered Hollow Drill RodsTapered 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.

A wide taper degree is normally used when drilling with high impact hydraulic rock drills in medium hard to hard and abrasive rock formations.

Generally, the lightduty rock drill uses 7 taper or smaller taper degree, the heavyduty rock drill mainly uses 12 taper degree.

The tapered drill rods have a tough life, transferring the percussion energy from rock drill to drilling bit and then into the rock. They’re also subjected to high bending stress, not to mention corrosive water in the flushing hole.

It is forbidden to keep working when the tapered drill rod is bended, otherwise the service life of the tapered drill rod would be decreased.

If the tapered drill rod was sheared, it can be restored by re-machining a new taper.

 

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.
