Bosch Expert HEX-9 HardCeramic Drill Bit 12 x 90 mm

The Bosch Expert HEX-9 HardCeramic Drill Bit 12 x 90 mm is a one-piece carbide cutting tool designed for tough surfaces. It is made specifically for drilling holes in hard ceramic tiles and similar dense materials. A built-in centring tip helps the bit sit correctly at the start of the hole, reducing wandering across the work surface. The design allows dry operation, so no continuous water cooling or lubrication is needed. Homeowners and tradespeople can use it for bathroom, kitchen, and general tiling installations. Use standard rotary mode only, as the bit is not intended for hammer drilling.

The grey bit connects directly to compatible power drills, rotary tools, and impact drivers. It has a hex shank that holds firmly in the chuck. This fit keeps power transfer stable when working through high-friction materials. Weighing 40 g, it adds little mass to the connected tool and slots into existing hardware kits for immediate use. Daily handling is straightforward, and no special adapters are needed.

• 12 mm cutting diameter for standard wall plug and anchoring requirements in hard ceramics.
• 90 mm total length gives sufficient reach for standard wall and floor tile depths.
• Solid carbide construction withstands high friction and keeps its cutting edge over time.
• Hexagonal shank profile prevents slippage in both standard and keyless drill chucks.
• Dry drilling capability removes the need for water-cooling setups during indoor renovations.
• Rotary-only design prevents tile cracking by excluding hammer action.
