The hammer features a heavy-duty piston, non-return valve (check valve), air distribution system, front chuck, and control tube assembly—all of which are easy to service and replace. Its design supports high frequency percussion, making it suitable for high-speed drilling, borehole straightness, and depth control in challenging conditions. Brands like Kings Mining Tools ensure precision and reliability in these components.
Benefits and Uses :
The DTH Hammer K47 is ideal for various percussive drilling applications, such as:
- Mining operations (coal, iron ore, limestone)
- Geotechnical and exploratory drilling
- Water well and geothermal drilling
- Foundation and piling work
- Blasthole drilling in quarries and construction sites
It offers low air loss, high energy efficiency, and minimal deviation, which ensures faster drilling speeds and reduces operating costs. The DTH Hammer K47 also supports multi-pass reaming, making it effective for projects requiring variable hole diameters. Its rugged design makes it suitable for overburden drilling, boulder penetration, and fractured rock formations. As a trusted DRILLING TOOL, Kings Mining Tools consistently delivers these benefits.
Why the DTH Hammer – K47 is Better
The DTH Hammer K47 offers a combination of power, reliability, and versatility, which distinguishes it from other models in the same class. Unlike imported hammers that may face long lead times or high servicing costs, the DTH Hammer K47 provides local manufacturing support, spare availability, and faster turnaround for maintenance. It is compatible with various DTH DRILLING TOOL bits, including carbide button bits, concave bits, and drop center bits, commonly used in rotary-percussive drilling systems.
Its optimized internal airflow increases bit face cleaning and reduces back pressure, resulting in improved penetration rates and extended bit life. Compared to brands like Halco, Atlas Copco, or Sandvik, the DTH Hammer K47 matches in quality but excels in cost-effectiveness, ease of integration, and after-sales support.
The DTH Hammer K47 stands out as a reliable, cost-effective, and high-performance solution for a wide range of drilling applications. Manufactured in India using advanced engineering techniques and premium-grade materials, including those by Kings Mining Tools, it offers the ideal combination of drilling speed, efficiency, durability, and ease of maintenance. With its compatibility across various drill rigs and bit types, along with strong local service and spare parts support, the DTH Hammer K47 is a top choice for contractors, mining operators, and infrastructure developers alike.
