Rockmore has become the industry’s performance leader in tools that withstand the toughest rock drilling demands. Our commitment to this degree of quality starts with extensive research and development. Rockmore includes some of the sharpest minds in the rock-drilling industry — a team of product designers, metallurgical experts and tool specialists who are continually advancing drilling technology for the entire industry. Our drilling tools are developed based on the continuous input of operators and contractors working in the field. We use the finest raw materials available, including premium steel and rugged carbide. That’s why our products exceed industry specifications for performance and safety.

When you work with Rockmore International, we are committed to your productivity and efficiency — and to your bottom line. Our quality means your success.

Rockmore International’s roots began in 1948, with the founding of the mining industry’s newest manufacturer, ThrowAway Bit Corporation. Named for its flagship single-use drill bit products, ThrowAway started with a commitment to quality – a promise to manufacture high quality bits from the toughest steel and carbide inserts available.

The company soon earned a reputation in the rock drilling industry for manufacturing bits that delivered the lowest cost per foot/meter drilled. Back then, these included tapered, cross, button and down-the-hole (DTH) bits in all international thread sizes and diameters. The company soon expanded its product line to include extension rods, couplings and shank adapters.

Success and growth were a natural result of the company’s forward-looking business ideals and a determination to provide the finest products at competitive prices.

In 1996, ThrowAway became Rockmore International, a change that reflected the company’s expanding role as a worldwide producer of a complete line of rock drilling tools.

In 1997, in a move to further diversify its product line and its market distribution, Rockmore acquired HP Rocbo GmbH, an Austrian manufacturer of surface and underground drill rods. This enabled Rockmore to bring its high level of quality and service to an ever-expanding global market of rock drilling operations. Rockmore now exports to over 75 countries, providing rock drilling tools for use in mining, construction, tunneling, water well, and quarrying projects around the globe.

Rockmore’s advance to industry leadership has been the direct result of their commitment to extensive research and development. Rockmore’s team of product designers, metallurgical experts and tool specialists – some of the sharpest minds in the drilling industry – have placed Rockmore at the forefront of drilling technology.

Rockmore revolutionized air flow management with its ROK series of high-performance DTH hammers, utilizing SonicFlow technology to minimize backflow and turbulence.

The innovative new XR32 thread design was developed to improve precision and efficiency in drifting and tunneling operations by providing a stronger and more powerful drill string.

And Rockmore´s new MultiPoint carbide insert design provides multiple strike points for more efficient rock fracture.

In November 2011, Rockmore released a new drill bit designed for hard rock drilling and blasting operations in tunneling. The B6 Drill Bit Design is intended to prolong bit life and increase drilling penetration rates by incorporating enhancements in cutting geometry.

In April 2012, Rockmore announced a new DTH hammer in its emerging Deep Hole series, the ROK 500DH. This 5 inch range hammer incorporates many new innovations and features characterized in the new Deep Hole class of DTH hammers.

In August 2012, Rockmore unveiled a new drill bit design especially suited for hard rock quarry drilling. The new CrossFlow Bit Design extends bit life and improves penetration rates for percussive drilling applications in abrasive and challenging rock condition.

In January 2012, Rockmore International announced the opening of an additional manufacturing center in Judenburg, Austria. Along with their existing plant in the USA, the 12,000,000 USD facility effectively doubled Rockmore's production capacity.

In 2013, Rockmore announced the first models in their new A Series DTH hammer product line – the ROK 600A and 650A hammers. These new hammers demonstrate better performance and penetration rates suited to smaller compressors.

With more than 60 years of hard work and a solid commitment to quality and service, Rockmore is dedicated to providing its customers with effective, innovative solutions in rock drilling tool technology.
