Description
Products Description
1. The hole-forming straightness is good and the drilling speed is fast.
The working principle of centering drilling can ensure that straight holes can be drilled in all strata such as gravel layer, sand layer and pebble layer, and the drilling speed is fast.
2. Less torque during drilling.
Centering drilling requires much less torque than eccentric drilling. The ring drill ensures smooth and stable drilling under all conditions, even if a small drilling rig is used, larger holes can be drilled.
3.Unlock-relocking is easier.
Sometimes it is necessary to unlock the system during drilling, and it is easy to re-lock the centering drilling, because there is no eccentric member in the system that must be opened and closed in the hole.
4. Drilling can be carried out at any angle.
The centering drilling tool can drill holes at any angle.
5. The slag discharge effect is good.

The centering drilling tool can drill holes at any angle.
5. The slag discharge effect is good.
In centering drilling, the air flow used for slag removal immediately rises along the casing after being ejected from the pilot bit, so the damage to the hole wall is small and the slag removal effect is good.
6. Easy operation and safe system.
6. Easy operation and safe system.
Because the centering drilling work is smooth, drillers don't need to pay continuous attention to drilling work.
7. Economy and low cost.
The structure and working principle of the centering drilling system can ensure that the downtime can be significantly reduced,with less consumables and low operating cost.
