HSOD508 Symmetric Overburden Drilling Equipment For Dimensional Stone Industry

Introduction of HSOD508:

Specification of SHOD406:

Advantages of symmetric drilling:

1. Sound drilling straightness and fast drilling speed

Theoretically, symmetric drilling makes sure the hole in all formations , such as gravel bed, sand bed and pebble bed etc, is consibly straight, the drilling speed fast and the drilling torque relatively small.

2. The torque necessary for symmetric drilling is much less than that for eccentric drilling

A smooth and steady drilling may be achieved using ring bit on all conditions and create big holes even if a small drilling rig is used.

3. Unlocking-relocking can be relatively easily achieved

Unlocking the system is sometimes required during the driling process. Relocking is easy since there are no eccentric components that must be opened or closed inside the hole.

4. Drilling can be carried out at any angle

Symmetric drilling can shape the hole at any angle.

5. Effective cuttings discharge

The air flow for cuttings discharge purpose during the casing pipe after spurting out from the pilot bit. Hence, the negligible damage on the wall of hole can guarante effective cuttings discharge.

6. Easy-to-operate and system security

Drilling workers are relieved of the need to maintain their continuous and constant attention on drilling process since symmetric drilling can carry on smoothly.

7. Economical and cost-effective

The structure and principle of operation of symmetric drilling system can guarantee considerable reduction in downtime, fewer consumables and lower operating costs.
