About Roschen
Roschen has a comprehensive range of rock drill bits that have been strategically designed to match all conceivable industries and applications. Each Roschen rock drill bit is made from the highest quality tungsten carbide steel and precision machined to produce a perfect drilling tool. These bits are then heat-treated to the proper hardness which facilitates excellent surface compression and fatigue resistance. Manufactured in-house, each bit is specially finished to the required shape and fitted with the correct sized button bits.
Roschen offers a variety of rock drilling bits, including: tophammer bits, rotary bits, tricone bits, DTH bits and PDC bits. We also stock and sell a great selection of bit thirds for horizontal drilling applications. Roschen offers five basic bit designs: Convex, Flat Front, SpeedBit, Concave, and Rocket Bit. These trademark designs are equipped to handle all types of rock drilling, whether hard or soft, abrasive or fractured.
