The Sandvik RH460 series of DTH hammers has been developed 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.

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 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.

The new Sandvik RH460 series hammers are now available in 4, 5, 6 and 8 in. (10, 12.7, 15 and 20 cm), with all versions being designed to utilize bits with generic shank types. The 5, 6 and 8 in. hammers also are available in heavy duty versions.
