Coal Mining Rock Drill Steel Rod , H22 Hex Tapered Hollow Drill Rod Color Custom

Water Well Drill Pipe Brief Introduction

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.

Hex tapered hollow drill rods for rock drill for jack hammer rock drill YT24,YT27,YT28,YT29A,S82 etc


Effective lengths: 400mm ~ 8000mm;
Taper degrees: 4°46’, 6°, 7°, 11°, 12°;
Shank sizes: Hex.19mm,Hex. 22mm, Hex.25mm;
Other lengths are available upon request.

1. The ordinary connection taper degree is 7º, 11º and 12º, other degrees like 4.8º, 6º and 9º are also available upon request;

2. The ordinary shank is Hex22 × 108mm, Hex25 × 159mm and other styles are also available if upon customers’ request;

3. The rod length must be specified in order;

4. In order to adapt to different rock conditions, the drill rod is selected by users.

Water Well Drill Pipe Characteristics

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.
