12° Hexagonal Steel Tapered Rod Carbon Steel Material For Blasting Holes

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.
