Diamond drill bit Bosch DIAMANTBOR TØR 38x150 mm 1/2" PROF

Bosch DIAMANTBOR TØR 38x150 mm 1/2" PROF is a diamond-tipped dry drilling bit engineered for creating precise holes in hard, dense surfaces. Designed for professional rotary tools with a 1/2" mount, this drill bit delivers controlled performance when working on ceramic tiles, porcelain, stoneware and similar materials typically encountered in construction, tiling and renovation projects.

Advantages

The diamond tip provides high wear resistance and sustained cutting capacity during dry drilling operations. Its 38 mm cutting diameter and 150 mm overall length allow for deep, accurate holes while maintaining stability and guidance. The 1/2" professional shank ensures secure attachment to compatible rotary equipment and reduces wobble for cleaner edges and consistent hole geometry.

Suitable for

• Drilling holes in ceramic tiles and porcelain
• Creating openings in stoneware and similar dense surface materials
• Professional tiling and renovation tasks requiring precise, repeatable holes
• Dry drilling where diamond cutting performance is needed

When it may not be suitable

This diamond dry drill bit is optimized for hard, brittle materials and not intended for general-purpose drilling in wood, metal or soft plastics. Using it in materials it is not designed for can reduce cutting efficiency and accelerate wear. For wet drilling applications or variable-speed use outside the recommended operating parameters, consider a tool or accessory expressly specified for those conditions.

Key specifications

• Cutting diameter: 38 mm
• Overall length: 150 mm
• Mount type: 1/2" professional shank
• Tip type: Diamond-tipped (dry drilling)

How to use

Mark the drilling position and secure the workpiece to prevent movement. Fit the Bosch DIAMANTBOR TØR into a compatible rotary tool with a 1/2" mount and set the tool to the recommended speed for diamond dry drilling as specified by the tool manufacturer. Apply steady, moderate pressure and keep the bit perpendicular to the surface. Pause periodically to allow the bit to clear dust and avoid overheating; use intermittent drilling if necessary. After completing the hole, remove dust from the bit and work area to maintain cutting performance.

What to consider before purchase

• Confirm your rotary tool accepts a 1/2" professional shank
• Verify the intended material is suitable for dry diamond drilling (ceramics, porcelain, stoneware)
• Assess required hole diameter and depth to ensure 38×150 mm meets the task
• Plan for dust extraction or dust control when dry drilling in enclosed spaces

Usage recommendations

For best results, use the Bosch DIAMANTBOR TØR with a stable drill stand or guide when possible, maintain correct tool speed, and avoid excessive pressure. Regularly clear dust to preserve diamond cutting action and extend bit life.
