Ceramic drill bit Bosch 10 x 90 mm for tile and porcelain drilling

The Bosch ceramic drill bit 10 x 90 mm is designed for precise drilling in ceramic tiles and porcelain. Its solid construction and tip geometry deliver clean holes with reduced chipping, making it suitable for installation work where neat finish and dimensional accuracy matter. The bit is compatible with standard rotary drills and intended for tasks such as fixing wall-mounted fittings, installing plumbing fixtures and electrical boxes, and other drilling operations in bathrooms and kitchens.

Advantages

This Bosch drill bit combines a durable shank and optimized tip shape to improve centering and reduce skidding on smooth surfaces. The construction resists wear during repeated use in hard ceramic and porcelain materials, helping to maintain hole quality over time. Designed for use with common rotary drills, the bit offers straightforward handling and predictable drilling performance.

Suitable for

• Drilling mounting holes for wall-mounted fittings and brackets in tiled walls
• Creating holes for plumbing fixtures and mixers through ceramic and porcelain
• Preparing openings for electrical boxes, conduits and cable routes in tiled rooms
• Installation work in bathrooms, kitchens and other tiled surfaces

Key specifications

• Tip diameter: 10 mm
• Overall length: 90 mm
• Material compatibility: ceramic tiles, porcelain
• Shank type: compatible with standard rotary drill chucks
• Intended use: dry drilling in tile and porcelain

How to use

Secure the workpiece and mark the drilling point. Use a standard rotary drill with an appropriate chuck and set a low to moderate speed to avoid overheating. Begin drilling with light, steady pressure to establish the hole and then continue with controlled feed until reaching the required depth. Avoid excessive lateral force to reduce chipping; if cutting through particularly hard porcelain, pause periodically to allow cooling.

Usage recommendations

For best results, use a depth stop or tape on the bit to control drilling depth, wear eye protection and a dust mask when drilling, and test on a scrap tile to confirm speed and pressure settings for your specific tile type.
