Diamond Core Bit INDIAN PROFESSIONAL KORONA DIAMENTOWA M14 32 mm, dry drilling

Diamond core bit INDIAN PROFESSIONAL KORONA DIAMENTOWA M14 32 mm is a compact cutting tool engineered for dry drilling in hard materials. The bit features a 32 mm cutting diameter and an M14 threaded connection, designed for use with compatible rotary tools and angle grinders. It is intended to create precise small-diameter holes in materials that require diamond cutting performance, such as ceramic tile edges, porcelain, natural stone and certain masonry surfaces.

Advantages

This diamond core bit provides high abrasion resistance and maintains cutting performance during dry drilling. The M14 thread ensures secure attachment to common grinders and rotary tools, while the 32 mm cutting diameter allows accurate, repeatable hole sizes for fitting fixtures or passing cables and pipes. The tool is compact and suitable for confined work areas, offering stable drilling with minimal chipping when used correctly.

Suitable for

• Drilling holes in ceramic tiles and porcelain
• Cutting small-diameter holes in natural stone and granite countertops
• Creating openings in masonry for anchor bolts and inserts
• Renovation and repair tasks requiring precise small holes

Key specifications

• Cutting diameter: 32 mm
• Connection type: M14 threaded shank compatible with angle grinders and rotary tools
• Cutting method: dry drilling with diamond segments
• Intended materials: ceramic, porcelain, natural stone, selected masonry

How to use

Select a rotary tool or angle grinder with an M14 thread and a suitable speed range for hard materials. Mark the drilling location and secure the workpiece to prevent movement. Start drilling at a low speed to establish the hole position, then increase speed as needed while applying steady, moderate pressure. Use short drilling intervals to limit heat build-up and clear dust frequently to maintain cutting efficiency. Allow the bit to cool between passes when necessary to prolong tool life.

Usage recommendations

Use appropriate personal protective equipment including eye protection, dust mask and hearing protection. For best results on brittle surfaces, support the reverse side of the material when possible and avoid excessive side loads. Although designed for dry drilling, monitor temperature and stop periodically to prevent overheating; consider light water misting only if compatible with the tool and operator safety.
