Sandvik Construction’s extensive range of rock tools are world renowned for combining advanced materials technology, with skillful design focusing on performance, simplicity and endurance. The latest member of the down-the-hole range is the RH460 series of hammers, which is now extended with even more sizes and models.

The new Sandvik RH460 series of DTH hammers has been developed in order to provide drilling customers with the enhanced levels of penetration rates, longer service life and lower operating costs that they now demand. Possessing key features that optimize the impact-energy transmission into the rock, utilizing very few parts, they are designed to be reliable, easy to service, and fast.

Continuous improvement has been the key to the development of the Sandvik RH460 series, and it has only been through the constant search for enhanced performance, through productivity and reliability, that has allowed Sandvik to deliver the operational improvements our customers demand from their DTH hammers.

Design, test and evaluate

The mantra behind the design has been to test and evaluate; this has led to the RH460 design being able to prolong hammer life and increase drilling penetration rates. At its core is the ability of the RH460 to utilize an enhanced air cycle which leads to a reduction in fuel consumption. Furthermore, the RH460 improves our customer’s productivity through high striking power and reliability through better lubrication capabilities and increased resistance against galling; all combined with developments in the piston bearing design. Put quite simply, the Sandvik RH460 series is a cost efficient DTH hammer.

The new Sandvik RH460 series hammers is now available in 4”, 5”, 6” and 8”, with all versions being designed to utilize bits with generic shank types. The 5”, 6” and 8” hammers are also available in heavy duty versions.

The uncompromising nature of the design, and the development of the concept being focused on operational efficiencies, will ensure that this ground breaking range of DTH hammers fulfills Sandvik’s commitment to – when the going gets tough, Sandvik gets tougher.
