Product Description

Symmetric Overburden Drilling Equipment Rock Drill Bit Well Drilling Tool Accessory

 

 

 

 

We, Shenyang ABT Drilling Equipment Co., Ltd. is a company mainly engaged in drilling equipments and tools. With over 20 years experience, our commitment to excellence ensures a reliable product that will perform every time. We utilize the latest technologies in engineering to produce cutting edge designs. We use methods that meet aerospace standards in manufacturing superior quality hammers and bits.

 

Advantages of symmetric Drilling

1.Great verticality of the hole and fast drilling speed.

Vertical holes can be drilled in all strata, such as gravel, sand and pebble, and drilling speed is fast. This is based on the principle of work.

2.The torque necessary for symmertic drilling is much less than for eccentric dirlling.

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

3.Unlocking-relocking can be relatively easily achieved.

  When the system needs to be unlocked during drilling, it is easier to unlock than eccentric drilling without opening and closing eccentric components in the hole.

4.Drilling can be carried out at ant angle.

  Symmetric drilling can shape the hole at any angle.

5.Effective cuttings discharge.

  The gas used for slag discharge in the center drilling rises along the casing immediately after it is ejected from the guide bit, so the damage to the hole wall is small and the slag discharge effect is good.

6.Easy operation and system safety

  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. Low cost

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