Product Details

The 7 Piece CYL-9 Multi Construction Drill Bit Set delivers stable drilling in all kinds of materials. Its centring tip provides a steady drilling start and good guidance universally. The diameter-optimised AWB brazing and hardening technology increases the robustness of the 2-cutter drill bit and reduces vibration during use.

Additionally, the bit's 4-flute dura design with a reinforced core section delivers better wear resistance and stability when drilling soft concrete. The bit is intended for practically all materials in interior fitting work, e.g. soft concrete, masonry, brick, cement asbestos, light building materials, multilayer materials, ceramics and tiles, wood, plastic, sheet metals and aluminium. The CYL-9 Multi Construction Drill Bit is equipped with diamond-ground cutting edges and a special ground tip, making it perfect for multipurpose drilling. Consisting of fine-grade highly durable carbide, this bit has extra-long life and offers the best wear resistance. As proof of quality, the drill bit bears the test mark of the PGM Masonry Drill Bit Association Board, guaranteeing compliance with tight tolerances, exact drilling and the firm hold of fixings. It is compatible with cylindrical shank systems for all corded or cordless drills, enabling perfect results when drilling with or without impact.

Bosch EXPERT Multi Construction TCT Drill Bit Set (7 Piece) is rated 4.6 out of 5 by 41.
Rated 4 out of 5 by from They not SDS strength but ok for tiles & walls if care is taken They are ok if you use water for cooling same as wet tile drills, I used the 5.5 mm & 6 mm with water but the first bit I used the 5mm overheated without coolant despite running on lowest speed, so it depends on the type of tiles & their thickness & how much force you apply to get the best out of these they will drill into brick & masonry on problem

Rated 1 out of 5 by from Only a home user poor, already gone rubbish and I'm only a home user. I have put up two solar lights and one shelf into tiles. The drill bits worked fine but any masonry and they are now going blunt.

Rated 5 out of 5 by from Great set I brought these just because i lost my other set and needed them for a job, and i should have brought these in the first point as they just effortlessly went into the brick walls and made nice clean hole

Rated 5 out of 5 by from Jack of all trades... Great time savers. Not the best in any one material but ideal if you need to blat some holes through battens into masonry in one hit etc. or just don’t want to go searching for the right bit, these will do it all.

Rated 5 out of 5 by from Best all round drill bits Excellant drill bits, the only ones I'll buy for my battery drill. Good for standard ceramic tiles too. Go for the 7 piece set instead of the 4 piece set, its a good selection of sizes including some longer bits.
