DTH Hammers & Bits
Choosing the right hammer is largely determined by the hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for cuttings to evacuate the hole.
ROSCHEN offers a wide range of world class quality grade, versatile DTH hammers on worldwide. Hammers are available for down hole and blast hole applications and use in nearly all ground conditions. HDD and Reverse Circulation hammers are also available on request.
Most DTH hammers are designed for use with the industry’s most common bit shank types. This allows for the use of one bit on multiple hammers.
