We continuously engage in research and development activities to meet our customers' needs with high-performance tools that maximize the performance and economy of varied types of machinery under all kinds of operating conditions
Applications
- Tools for Rock Drilling (Mining, Quarrying, Tunneling and Civil Construction)
- Tools for Casing Installation (Casing for water/geothermal well, Piling for foundation, ground support and so on)
- Tools for Urban Development(Foundation, Underground development)
Mining
The origin of MITSUBISHI MATERIALS HARDMETAL's ROCK TOOLS is our own mining business from more than 140 years ago.MITSUBISHI MATERIALS HARDMETAL's ROCK TOOLS is set apart from the others with in-house produced carbide buttons using a technology that has been cultivated for many years.The products offer solutions that achieve the customer’s target in both open-pit and underground mining.
Tunneling
Due to mountainous geographical conditions in Japan that requires a lot of tunnel construction, we have been one of the leading experts in tunneling in the world.
MITSUBISHI MATERIALS HARDMETAL's ROCK TOOLS offers a full range of products for advanced technology in tunnel engineering all over the world.
Construction
MITSUBISHI MATERIALS HARDMETAL's ROCK TOOLS provide the best solution for all types of applications in construction, including civil engineering projects, tunneling, surface drilling, anchoring, foundation projects, and piling.
Water wells
MITSUBISHI MATERIALS HARDMETAL's ROCK TOOLS has a unique product lineup for the water well and piling industries.For overburden drilling, we offer world class Super MaxBit (SMB) and Ultra MaxBit (UMB) products in addition to conventional DTH bits.SMB and UMB products provide our customers to install casing or piling with ease in all types of rock formations and hole depths.
Quarrying
MITSUBISHI MATERIALS HARDMETAL's ROCK TOOLS is one of leading brands in the stone/aggregate industry. Our products give better efficiency with high penetration rates and less hole-deviation.
Casing / Piling

Drifting / Tunneling Equipment
MITSUBISHI MATERIALS HARDMETAL's ROCK TOOLS for small/ medium sized drill holes for drifting are available with extensive range of size and design by threads type in the market.
Bench / Long Hole Drilling Equipment
MITSUBISHI MATERIALS HARDMETAL's ROCK TOOLS for bench and long-hole drilling are available with extensive range of size and design by popular threads type in the market.
Down The Hole Bits
We offer a wide assortment of Down The Hole bits, from 90 mm to 254 mm for different kinds of hammers.
SUPER MAXBIT
The SUPER MAXBIT consists of two or three wings on a device. Bit wings become extendable / retractable when drill strings rotate in the forward / reverse direction.
SUPER MAXBIT G-MODEL
The SUPER MAXBIT G-MODEL consists of two or three wings on a device same as SUPER MAXBIT, The G-MODEL provides optimum efficiency when drilling hard rock formations.
ULTRA MAXBIT
The ULTRA MAXBIT is used for simultaneous drilling and casing in unstable soft ground formations, such as sand, gravel and boulders.
Terminology
- New Austrian tunneling method (NATM)
- NATM is a method of modern tunnel design and construction to optimize various wall reinforcement techniques based on the type of rock encountered as tunneling progresses. In this method, concrete is sprayed onto an excavated area to quickly harden it, and rock bolts that secure the rock and concrete are driven deep into the bedrock to support the tunnel by using the bedrock's inherent geological strength.
- All ground fastened (AGF) construction method
- The AGF construction method is to support tunnel in excavations by piling outer circumference of the tunnel. Then grout is injected into the pipes to strengthen the foundation to prevent weak ground areas from collapsing.
