Dry drill set Bosch Dry Speed 6–12 mm, diamond-tipped core bits

Bosch Dry Speed 6–12 mm diamond-tipped core bit set is engineered for dry drilling in hard surfaces such as ceramic tile and similar materials. The set includes core bits with diameters from 6 mm to 12 mm, each fitted with diamond-cut edges to provide faster penetration and longer life when drilling without water. Designed for renovation, installation and professional repair tasks, the set aims to deliver precise, round holes with reduced dust generation compared with conventional carbide bits.

Advantages

The diamond-tipped cutting edges improve wear resistance and maintain cutting performance over multiple holes. Dry drilling capability removes the need for water cooling and simplifies on-site use in indoor environments. The compact set provides a range of commonly used diameters for small-to-medium holemaking, while the reinforced bit bodies ensure stability and consistent hole quality in tile and similar hard materials.

Suitable for

• Drilling holes in ceramic and porcelain tile
• Creating openings for fixtures and fittings during renovation
• Installation tasks requiring precision holes in hard surfaces
• Repair work where water use is impractical

Key specifications

• Diameter range: 6 mm, 8 mm, 10 mm, 12 mm
• Tip type: diamond-tipped cutting edge for hard surfaces
• Intended drilling mode: dry drilling (no water required)
• Material compatibility: ceramic tile, porcelain, similar hard surfaces
• Typical applications: precision core drilling for fixtures and fittings

How to use

Select the core bit size matching the required hole diameter and mount it securely in a compatible drill or rotary tool with the appropriate chuck. Position the bit perpendicular to the work surface and begin drilling at low speed to establish the cutting edge contact, then use moderate, steady pressure and increased speed as the bit engages. Periodically withdraw the bit to remove debris and allow the diamond edge to cool; avoid applying excessive lateral force. For best results, clamp or support tiles to reduce vibration and prevent cracking.

Usage recommendations

Use personal protective equipment, including safety goggles and a dust mask, and ensure adequate ventilation when dry drilling. Match drill speed and feed pressure to the tile material; start slowly and increase speed only when the cutter is cutting smoothly. Inspect bits regularly for wear and replace when cutting efficiency decreases to maintain hole quality.
