Bosch Expert 7 Piece CYL-9 Multi Construction Drill Bit Set

The Bosch Expert 7 Piece CYL-9 Multi Construction Drill Bit Set is a versatile multi-material drill bit set designed for professional use across a wide range of substrates, including granite, concrete, brick, soft tile, wood, and metal.

Built around the EXPERT CYL-9 Multi Construction Cylindrical Drill Bit, this set delivers up to 5x greater precision than the Bosch CYL-3, making it a reliable choice when accuracy matters. The advanced carbide tip is produced using a fine grinding technique that achieves razor-sharp cutting edges, enabling complex, highly efficient geometry that reduces skidding even on hard, smooth surfaces such as granite.

The Bosch Centering Geometry ensures a slip-free start and stabilised drilling action from the first contact, while the optimised dust extraction channel works in combination with the fluting to promote efficient chip removal. The cylindrical shank is compatible with standard three-jaw drill chucks, making this set straightforward to integrate with existing tools on site.

This seven-piece set covers diameters from 4mm to 12mm, making it well suited to fixings, cable routes, pipework penetrations, and general construction tasks where multiple materials may be encountered in a single job.
