4'' High Air Pressure DTH Hammer for Mining Compatible with Bit Shank HD45A
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. Capable of drilling in practically any type of ground.
2. Constant energy behind the bit allows for faster drilling with less power loss and better hole accuracy.
3. The elimination of foot valve associated with the drill bit offers various technical and economical advantages.
4.The air flowing through the hole ensures efficient flushing and cleaner holes. With the same hammer, you may make a variety of hole diameters.
