Bosch Expert 4 Piece CYL-9 Multi Construction Drill Bit Set

The Bosch Expert 4 Piece CYL-9 Multi Construction Drill Bit Set is a versatile multi-material drill bit set designed for tradespeople who need reliable, precise drilling across a wide range of substrates.

Modern construction rarely involves just one material, and switching between drill bits wastes valuable time on site. This set tackles concrete, brick, soft tile, wood, metal, and even hard materials such as granite without skidding — making it genuinely useful for contractors, joiners, electricians, and plumbers working across mixed-material builds.

The performance advantage comes from Bosch's fine-ground, optimised carbide tip combined with a specially engineered centring geometry. This slip-free start and stabilised drilling action delivers up to 5x more precision than the Bosch CYL-3, helping you produce clean, accurate holes consistently across hundreds of uses.

The cylindrical shank is compatible with standard three-jaw drill chucks, and the optimised fluting works alongside the tip to extract chips and dust efficiently — keeping the drilling process fast and reducing the risk of bit overheating or binding.
