📝Product Description

Due to economy and powerful drilling capacity, the down the hole hammer has become an advanced drilling tool for the drilling and mining industries. Down the hole hammers and drill bits are designed together to work in perfect unison, providing high penetration rates, long service life, and low costs.

Maximum Energy Transfer: Fast drilling speed and low air consumption due to the special inner structure designed according to the latest rock drilling theory.
High Durability: Smooth performance and long service life thanks to high-quality alloy steel materials and advanced processing technology.
Easy Maintenance: Low problem rate and simple assembly/disassembly due to the reliable inner structure.
Easy Bit Removal: Multi-head thread connecting chuck and cylinder makes it easy to depart the bit from the hammer.
Compatibility: Fully interchangeable with DTH bits and drill pipes.

Applications:

High pressure drilling rigs
Water well drilling
Record breaking penetration
Bench drilling
Mining / Mineral Exploration

Civil Engineering Applications
Oil well drilling
Foot Valve not required in the bit
Maximizes efficiency
Penetrate 15% to 30% faster
