Bosch Expert HEX-9 HardCeramic Drill Bit Set (5 pieces) 4–10 mm

The Bosch Expert HEX-9 HardCeramic Drill Bit Set (5 pcs) 4–10 mm is a 5-piece carbide drill bit set designed for drilling into hard, brittle surfaces. The bits are built to withstand the abrasive nature of masonry materials. The set is used to drill clean holes in glass, soft tile, hard ceramic, stone, and roofing tile. It covers the needs of tradespeople and DIY users working on bathroom and kitchen installations. Performance stays consistent during repeated use, and the bits help simplify drilling on fragile materials.

Each bit has a hex shank for secure clamping and efficient power transfer. This fits standard drill chucks and impact drivers and prevents slippage under load. The bits are designed for accurate hole positioning on delicate surfaces. Controlled material removal reduces the risk of chipping or cracking the workpiece. A unified profile across the set gives predictable handling regardless of diameter. Proper storage keeps the cutting edges in good condition for future jobs.

• Included diameters of 4.0, 5.0, 6.0, 8.0, and 10.0 mm cover the standard sizes needed for most wall anchor installations.
• 90 mm overall length provides enough clearance when drilling through thick roofing tiles and deep backing layers.
• The specialised tip geometry allows immediate, accurate starts on smooth surfaces without the bit wandering.
• The protective carrying case has individual slots to keep the bits organised and protected during transport.
• Dry drilling capability removes the need for liquid coolant when working directly on glass and tile.
