Superior Wear Resistance SD8 8'' DTH Drill Hammer for Water Well Applications
Product description
Our hammer and bits are made of high quality alloy steel with advanced heat treatment to assure the good drilling performance and long service life. They are widely used by our customers all over the world.
Down The Hole hammer are produced from premium quality alloy steel for increased durability and wear characteristics. Specific heat treatment standards and special "stress relief" processes ensure consistent performance. DTH hammer are designed for maximum performance and hole cleaning ability and high penetration rate.
Product Advantages:
1. The well drilling equipment carries with larger power of impact frequency and torque, thus ensuring faster penetration. Compared with others, the efficiency can be improved 10%.
2. High grade alloy Steel and advanced heat treatment offer superior wear resistance..
3. Lower energy consumption, high impact frequency and superior energy transfer.
4. This DTH tool has large air output, which specially designed for water well users and enables it to flush out cuttings in deep hole drilling works.
