Drill bit Bosch Expert HEX-9 HardCeramic, 7 mm diameter, 90 mm length

The Bosch Expert HEX-9 HardCeramic drill bit is a specialised 7 mm diameter, 90 mm overall length tool engineered for drilling ceramic tiles and other hard surfaces. Its HEX-9 shank ensures a secure grip in compatible chucks and quick-change holders, while the tip geometry and carbide-tipped design deliver precise holes with reduced chipping on glazed surfaces. The bit is intended for professional and DIY tasks where controlled, clean drilling of ceramic materials is required.

Advantages

The HEX-9 shank provides improved torque transfer and reliable insertion into compatible quick-change systems, minimising slippage during use. The drill geometry and hard tip material are optimised for cutting through glazed tile and ceramic with reduced risk of cracking or chipping. Its 90 mm overall length gives sufficient reach for standard tile installations while maintaining rigidity for accurate hole positioning.

Suitable for

• Drilling holes in ceramic wall and floor tiles
• Creating openings for fixtures and fittings in bathrooms and kitchens
• Installation of anchors or inserts in ceramic surfaces
• Use with compatible corded and cordless drills that accept HEX-9 shanks

Key specifications

• Overall length: 90 mm
• Shank type: HEX-9 shank for secure grip and torque transfer
• Intended material: ceramics and other hard glazed surfaces
• Tip: hard-tipped geometry for reduced chipping on glazed tiles

How to use

Mark the drilling point on the ceramic surface and, if possible, use masking tape to reduce slippage. Fit the Bosch Expert HEX-9 HardCeramic bit into a compatible drill or quick-change holder ensuring the HEX-9 shank is fully engaged. Start drilling at low speed with moderate, steady pressure; increase speed gradually once the tip has established a groove. Avoid applying excessive axial force; let the bit do the cutting. Periodically withdraw the bit to remove dust and avoid overheating. For through-holes, support the back of the tile where practical to reduce breakout.

Usage recommendations

Use appropriate personal protective equipment including safety glasses and gloves. Select drill speed suitable for ceramic materials and, where recommended by the drill tool instructions, use light cooling or intermittent breaks to prevent overheating. Confirm compatibility of the HEX-9 shank with your drill or adapter before use.
