DTH Hammer Bits with Shank QL Series for Water Well Geothermal Drilling

Product description

Sollroc's DTH hammer and bit are made by finest mechanical process, special heat treatment with intensive quality control by our engineers. With such effort, we have been manufacturing various products which have outstanding drilling speed, and pressure intensity with effective air pressure transmission.

Therefore, our products are widely utilized in wide range of construction sites.

Product Advantages:
1. Less amount of drilling fluid and additives are required.
2. Less weight-on-bit allows for lighter rigs that are easier to set up and takedown.
3. Since cutting force is supplied by reciprocal force, the bit encounters lesser deflection and therefore drills more precisely.
4. Rate of penetration of DTH is 2-5 times greater than the rotary drilling technique.
5. Lesser time consumed compared to when the contractor has to be changed when geology changes.
