Why Choose Us
MSD is a China-based rock drilling tools manufacturer supplying DTH drilling tools for conventional down-the-hole and reverse circulation drilling systems.
The current product range is organized into seven categories: DTH Drill Pipes, RC Hammers, RC Drill Bits, DTH Shock Absorbers, DTH Adapter Subs and Crossover Subs, DTH Back Hammers, and DTH Hammer Breakout Benches.
Use the product cards on this page to review each category and compare its available models, sizes, connections, matching requirements, and configuration information. The product category name alone does not confirm the final model or compatibility with an existing drilling system.
MSD supplies DTH drill pipes, shock absorbers, adapter subs, crossover subs, back hammers, and hammer breakout benches as separate product categories because each tool has different matching and operating requirements.
DTH adapter subs and crossover subs should be selected according to the required connection arrangement. DTH hammer breakout benches should be reviewed according to the hammer range, clamping requirements, and confirmed operating method. Drill pipes, shock absorbers, and back hammers should also be checked against the relevant models, connections, dimensions, and drilling requirements.
Similar product names, nominal sizes, or connection descriptions do not automatically establish interchangeability. Existing product markings, drawings, photographs, samples, and previous order information should be used where available.
The MSD DTH drilling tools range also includes RC hammers and RC drill bits for reverse circulation drilling systems.
RC hammers and RC drill bits should be reviewed as matching components. The exact RC Hammer Model, Bit Shank, required bit diameter, drill-pipe arrangement, rig information, and complete RC system requirements should be confirmed before ordering.
Conventional DTH hammers and conventional DTH drill bits are provided through their dedicated product ranges. This page focuses on the seven supporting-tool and reverse-circulation product categories listed above.
The suitable DTH tool depends on the product category, exact model, thread or connection type, required dimensions, matching hammer, bit or drill pipe, drill-rig information, drilling application, and actual operating conditions.
For replacement requirements, the current product model, markings, dimensions, connections, photographs, drawings, or samples should take priority over a general product description. For new drilling systems, the complete hammer, bit, drill pipe, connection, rig, and air-supply arrangement may need to be reviewed together.
Standard models, special connections, replacement configurations, and non-standard requirements can be reviewed with the MSD team. Confirmed product-specific information is provided on the corresponding product pages.
MSD is a China-based rock drilling tools manufacturer with 23 years of manufacturing experience, exporting drilling products to customers in 40+ countries.
The MSD product range includes DTH hammers, DTH drill bits, DTH drill pipes, RC hammers, RC drill bits, casing systems, top hammer tools, and related drilling components.
The technical team can review standard replacement requirements, new drilling-system configurations, special connections, non-standard models, drawings, samples, and project-specific product requests before confirming an available configuration.
This review helps reduce model and connection mismatch risks while providing a clearer technical basis for quotation, production, and order confirmation.
For a DTH drilling tool recommendation or quotation, provide the required product category, model, dimensions, thread or connection details, matching hammer, bit or drill-pipe information, drill-rig information, drilling application, operating conditions, and required quantity.
For replacement products, also provide the existing model number, product markings, photographs, drawings, dimensions, or samples where available. For RC products, provide the exact RC Hammer Model, required Bit Shank, bit diameter, and complete RC drilling-system information.
For special connections, non-standard dimensions, customized products, or project-specific requirements, send the available technical information to MSD for separate review.
