Mission DTH Tools
Roschen Mission's DTH products have several important advantages, the market's most comprehensive drilling product portfolio, and access to technology provided in specialty steel sand cemented carbides designed through Roschen group, its parent company. These materials are used in virtually all rock-drilling tools. Roschen Mission develops and manufactures drilling products characterized by uniform quality and excellent performance standards.
DRILLING HAMMERS
The introduction of the Mission 6 DTH percussive drilling hammer is creating new drilling milestones through the industry. The innovative mirror-impact-technology is revolutionary hammer design. It is about transferring the most hammer energy into rock breaking. The scientifically developed new piston and drill bit shapes optimize the drilling process. The Mission 6 is a hammer that is not only the fastest, but also the shortest, simplest in design and contains the fewest parts. This means quicker service and less parts failure. The Mission 6 requires no bit foot valve, no make up rings, and no moving air control valve. It also has a reversible piston case and a lubricated 12-spline shank.
Roschen Mission manufactures a full line of DTH percussive hammers with capabilities of drilling holes from 3-3/8" (87 mm) with a Hammer drill XL 3 to 43" (1102 mm) with an Hammer drill XL 32.
