Highest Drilling Speeds - The SDS max-7 Drill Bit is ideal for use at the highest drilling speeds. Its solid carbide S-cutter and inclined side cutters enable very fast drilling. Furthermore, the bit´ more→s vibration-optimised flute design offers the best power transfer and increases in speed. This product is intended for use in concrete and reinforced concrete, limestone and masonry. It is compatible with rotary hammers with SDS max holders. To achieve accurate results, the visibility of the wear mark indicates if the diameter of the hole is still in tolerance for metal anchor setting. As proof of quality, the drill bit bears the test mark of the PGM Masonry Drill Bit Association Board, guaranteeing c…

Lasting Performance in Concrete - The CYL-3 Drill Bit provides lasting performance when drilling concrete. Its stamina is a result of a highly durable carbide blend specially developed and manufacture more→d by Bosch. The blend is adapted to meet the demands of repeated use and offers high wear resistance when working with concrete. Moreover, the effective 2-flute U-shape design of the bit provides good dust removal, reducing friction, heat development and wear, resulting in an extended lifetime. The bit delivers lasting performance when drilling holes for fixings in abrasive materials such as concrete and natural stone. It is compatible with cylindrical shank systems for all corded or cordless impact …
