    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.
