Product Description

Low Air Pressure DTH Hammer CIR76A for Well Drilling, DTH Hammer and Bit
 

D Miningwell was founded in Quzhou city, China in 2001. For more than 20 years production and operation process. D Miningwell has been on the leading edge of mining equipment. We has its own drilling rig, DTH hammer, and drill pipe production workshops. provides a wide range of quality tools to mining, tunnelling, quarrying, water-well projects and urban transportation construction. D Miningwell is committed to providing customers with the most efficient and cost-effective drilling solution. Our team of drilling specialists are standing by to assist.

Water well drilling hammer is mainly used in mining, quarry, road construction and other engineering drilling blasting holes, landslide protection, dam site reinforcement, anchoring and other engineering holes, hydrology, water well holes and other fields.

1. The drill bit does not require nylon tubes, thus eliminating the trouble of nylon tubes being broken, damaged and hard due to thermal expansion and contraction.

2. DTH hammer without nylon tube has low energy consumption, high impact frequency, and the drilling speed is 15%-30% faster than the same type of DTH hammer with nylon tube.

3. Because the structure is very simple and the components are reliable, DTH hammer is easy to maintain and has a longer service life.
