Robert Bosch EXPERT HEX-9 Hard Ceramic Drill Bit – 10mm x 90mm

Note: Packaging may vary.

Product Details

The Bosch EXPERT HEX-9 HardCeramic Drill Bit (10mm x 90mm) lasts up to 10x longer than standard Bosch CYL-9 Ceramic drill bits. As modern wall tiles have become larger, thicker, and harder, drilling holes in them places immense demand on standard bits. Built with Bosch Carbide Technology—the hardest of metals—this specialist drill bit is engineered to effortlessly dry-drill hard ceramic and porcelain tiles without requiring water cooling or lubricants.

Featuring an advanced, fine-ground multi-faceted tip design, it distributes the workload across multiple asymmetric faces. This precision head allows for an exact, accurate start without skidding or scratching delicate tile surfaces. Equipped with a standard 1/4" Hex shank, it ensures maximum torque transmission and a firm grip in both three-jaw chucks and 1/4" internal hex tool holders.
