Product Description

Specification

The down-the-hole hammer cooperates with the down-the-hole drilling rig and the dth drill bit, and is mainly used in the construction of mining, marble quarry blasting hole drilling, water well drilling engineering or drilling and other engineering construction.
 

1. D Miningwell DTH hammer is a valve-type central exhaust impactor, which has a good effect of discharging rock powder, reduces the repeated crushing of rock slag, reduces the wear of the drill bit, and improves the drilling efficiency;

2. The internal structure size of the impactor is designed with advanced rock drilling theory, so that the impactor can obtain ideal energy transfer, large single impact power, faster rock drilling speed and lower air consumption;

3. Using high-quality raw materials and advanced processing technology, the performance is more stable and the service life is longer.

4. Easy disassembly and assembly, low failure and convenient maintenance.
