PRO 7 Piece CYL 3 Concrete Drill Bit Set

The Bosch PRO 7 Piece CYL-3 Concrete Drill Bit Set is a professional masonry drill bit set designed for lasting performance when drilling into concrete and natural stone. Built around Bosch's highly durable carbide blend, the CYL-3 bits are engineered specifically to withstand the demands of repeated use. This specialist carbide formulation offers excellent wear resistance, making these bits a reliable choice for contractors and tradespeople who need consistent results across multiple applications. The effective 2-flute U-shape design promotes efficient dust removal during drilling, reducing friction and heat build-up that can shorten bit life. This considered geometry helps extend the working lifetime of each bit, keeping performance consistent even in abrasive materials such as concrete and natural stone. Each bit in the set carries the PGM Masonry Drill Bit Association Board test mark, confirming compliance with tight manufacturing tolerances. This certification gives confidence that holes are drilled accurately and fixings will seat firmly — important on any site where structural reliability matters. The cylindrical shank design is compatible with standard three-jaw drill chucks, making the set suitable for use with both corded and cordless impact drills.
