Product features of DTH Hammers and bits
China DTH Hammer Suppliers and Manufacturers
With professional experience in the production and manufacture of
DTH hammers, our factory can provide you with high pressure and
medium and low pressure DTH hammers. It strictly complies with API
standards and other Chinese industry standards. Produced with
advanced craftsmanship and high-quality materials, it is durable.
It also has the following advantages:
1. The special internal structure of HD series DTH hammers designed
according to the latest rock drilling theory provides maximum
energy for the drill bit, fast drilling speed and low gas
consumption.
2. HD series DTH hammers are made of high-quality alloy steel
materials and advanced processing technology, with stable
performance and long service life.
3. The internal structure of the hammer head is simple and
reliable, easy to disassemble and assemble, with low failure rate
and convenient maintenance.
4. The multi-head thread connects the chuck and the hammer
cylinder, so that the drill can be easily separated from the
hammer.
5. Interchangeable with DTH drill bit and drill pipe
DTH
DTH bits are also our main product. After years of exploration, we
have rich experience in developing and manufacturing high-quality
products, using high-quality raw materials, advanced technology,
and passing strict inspections.
1. High and low pressure DTH drill bit
2. Diameter of low air pressure hole: 65-220mm
3. Diameter of high air pressure hole: 85-305mm
4. Surface type: drop center / concave / convex / double gauge /
plane
5. Our DTH bits can be applied to many types of DTH hammers, such
as XL, Mission, COP, IR, Mach, Demag, SD, Bulloc, Halco Mach,
