🛠️ Product Description
High air pressure DTH hammer is a kind of down-the-hole hammer, mainly used for percussive drilling in rock formation. Characterized by high air pressure and high efficiency, it is ideal for areas with abundant air supply. Using compressed air to drive the piston, it generates high impact energy to drill efficiently into rock.
Because of economy and powerful drilling capacity, down the hole hammers are advanced drilling tools for mining industries. Designed to work in unison with drill bits, they provide high penetration rates, long service life, and low operational costs.
- Maximum energy delivery to the bit for fast drilling and low air consumption.
- High-quality alloy steel materials and advanced processing technology for long service life.
- Simple inner structure for low maintenance and easy assembly/disassembly.
- Multihead thread connecting chuck for easy departure of the bit from the hammer.
- Fully interchangeable with standard DTH bits and drill pipes.
