🚀Product Description

High air pressure DTH hammer is a specialized down-the-hole tool designed for high-efficiency percussive drilling in rock formations. By utilizing compressed air to drive a reciprocating piston, it generates powerful impact energy directly to the drill bit. This tool is widely recognized in mining, quarrying, and construction industries for its economy and formidable drilling capacity.

Key Advantages:

Maximum energy delivery to bit
High penetration rates (15% to 30% faster)
Low air consumption inner structure
High-quality alloy steel materials
Simple, reliable, and easy maintenance
Easy bit separation with multihead thread
