DTH Hammers

DTH Hammer Sizes and Product Range

MSD is a China-based DTH hammer manufacturer and supplier, offering down-the-hole hammers for mining, quarrying, water-well drilling, foundation work, construction, and other rock-drilling requirements.

The standard MSD product range covers hole diameters from Ø90 mm to Ø864 mm across seven standard size categories: 3 Inch, 4 Inch, 5 Inch, 6 Inch, 8 Inch, 10–15 Inch, and 18–24 Inch DTH hammers. Each category includes confirmed hammer models with different hole ranges, bit shanks, connections, dimensions, and operating requirements.

MSD also supplies CIR series Low Pressure DTH Hammers for 50–178 mm holes, with a confirmed working pressure of 0.5–1.0 MPa. Current models include CIR50, CIR76A, CIR90A, CIR90B, CIR110A, and CIR150A; exact model-specific parameters are listed on the low pressure product page. This is a separate pressure-based product type, not an additional standard size category.

Use the product cards on this page to review the corresponding standard size category or low pressure series and compare its available models and parameters. The nominal hammer size alone does not confirm the final configuration.

Mainstream DTH Hammer and Bit-Shank Systems

MSD supplies DTH hammers for mainstream bit-shank systems commonly used in the international drilling market, including DHD, QL, MISSION, SD, COP, and NUMA series. Available hammer models, bit shanks, hole ranges, connection types, and dimensions vary by product category.

A similar hammer size or series name does not automatically confirm compatibility. The exact hammer model, bit-shank designation, connection, and confirmed dimensions should be checked before ordering.

Low-pressure CIR configurations are available separately for drilling systems operating within the confirmed CIR pressure and hole-size range.

Other hammer models, shank systems, special connections, and non-standard configurations can be reviewed or customized with the MSD team based on the supplied drilling requirements.

DTH Hammers for Rock Drilling Applications

MSD DTH hammers are supplied for mining and blast-hole drilling, quarry drilling, water-well drilling, foundation and piling work, construction and infrastructure drilling, and large-diameter rock-drilling projects.

The suitable downhole hammer configuration depends on the required hole diameter, hammer model, bit shank, connection arrangement, drill rig, compressor, and actual drilling conditions. The corresponding product pages provide confirmed model-specific information for further comparison.
