Mitsubishi Rock Tools

Mitsubishi Rock Tools are high-performance rock drilling tools manufactured from wear-resistant steel with in-house produced Japanese tungsten carbide inserts. They are used in mining, quarrying, tunneling, civil construction, water well drilling, and foundation piling. Argentium.in is India’s authorized supplier, offering the full Mitsubishi Rock Tools lineup for underground and surface drilling applications.

Mitsubishi Rock Tools are produced using advanced Japanese carbide technology developed over 140+ years of in-house mining experience. The tungsten carbide inserts are engineered for maximum wear resistance, longer bit life, and consistent penetration rates — reducing drilling costs per meter significantly compared to generic alternatives available in the Indian market.

Argentium supplies the complete range of Mitsubishi Rock Tools, including Top Hammer Drilling Tools (bits, drill rods, shank adapters), Down-The-Hole (DTH) Hammer Bits, Tapered Drill Bits, Integral Drill Steels, and specialty products like the Super MaxBit (SMB) and Ultra MaxBit (UMB) for simultaneous drilling and casing in overburden conditions.

Top Hammer tools transfer percussive energy from the surface through drill rods to the bit — ideal for small to medium drill hole sizes in drifting and tunneling with jumbo rigs. DTH tools place the hammer directly above the drill bit at the bottom of the hole, making them suited for deeper, larger-diameter drilling in quarrying, water wells, and blast hole applications where straighter holes and higher penetration rates are needed.

For tunnel construction, Mitsubishi’s Top Hammer Tools — specifically thread-type drill bits (R32, R38, T38, T45, T51) and matching rods — are widely used with modern jumbo drilling equipment. For weak ground and forepoling, the AGF Tools (casing advancement system) are recommended. Argentium.in can advise on the correct product selection based on your rock formation and tunnel diameter.

The Ultra MaxBit is a multifunctional simultaneous drilling and casing system designed for unstable soft ground formations including sand, gravel, cobbles, and boulders. It installs the casing at the same time as drilling, preventing borehole collapse. It is ideal for water well drilling, foundation piling, and geotechnical investigations in loose overburden where conventional drilling fails.

Mitsubishi offers multiple carbide button geometries including the innovative Samurai button shape, which extends bit life and improves penetration efficiency in abrasive hard rock formations. Other standard shapes include spherical, ballistic, and semi-ballistic buttons, each optimized for specific rock hardness and drilling conditions. Argentium can help select the right button shape for your geology.

Shank size must match your drill rig’s chuck and drifter system. Common Mitsubishi shank adapters include T38, T45, and T51 for medium-to-heavy equipment. For light equipment and handheld drills, tapered shanks (11°, 12°, 7°, 6°) in diameters from 30mm to 43mm are available.

Yes. Mitsubishi Rock Tools are designed to be fully compatible with modern hydraulic jumbo rigs, crawler drills, and drifters. The product range is engineered to match industry-standard interfaces — enabling seamless integration with equipment from leading OEMs used across Indian mines and tunnel projects, including those operating under DGMS-regulated underground coal and metal mines.

Bit life varies by rock hardness, drilling parameters, and flushing efficiency. In medium-hard granite (UCS 100–150 MPa), Mitsubishi DTH bits typically deliver 500–1,500 meters per bit. Top Hammer bits in tunnel drifting conditions average 200–800 meters. Mitsubishi’s superior carbide quality consistently delivers longer service life than many competing brands, lowering the cost per meter drilled.

Argentium provides technical support including product selection advice, on-site application guidance, and troubleshooting for drilling performance issues. As India’s authorized Mitsubishi Rock Tools supplier, Argentium offers fast delivery from its New Delhi base to project sites across India.

Yes. Mitsubishi offers a specialized product range for the water well and piling industry, including DTH bits and the Super MaxBit (SMB) / Ultra MaxBit (UMB) overburden drilling systems. These tools are engineered for deeper boreholes through mixed formations — rock, soil, and gravel — common in Indian water well drilling conditions. Argentium supplies these tools across India.

Mitsubishi Rock Tools are available in all major thread standards used globally and in India, including R25, R28, R32, R38, T38, T45, T51, and COP series. This wide range ensures compatibility with virtually every percussion drill rig on the market. Argentium can confirm the correct thread type for your specific rig model before ordering.

Mitsubishi Rock Tools reduce total drilling cost through three key mechanisms: longer bit life (fewer replacements per project), higher penetration rates (more meters drilled per shift), and fewer equipment breakdowns due to superior steel and carbide quality. When calculating cost-per-meter rather than cost-per-bit, Mitsubishi tools consistently outperform cheaper alternatives — especially in hard and abrasive Indian rock formations like basalt, quartzite, and granite.
