## Summary description

Diamond core drill bit INDIAN PROFESSIONAL KORONA M14 with 40 mm cutting diameter designed for dry drilling. Manufactured for use with M14-threaded angle grinders and rotary tools, it enables cutting and coring in hard materials such as tile, ceramic, porcelain and stone. Suitable for renovation, installation and tile fitting tasks requiring precise circular holes without coolant.

## Long description

Diamond core drill bit INDIAN PROFESSIONAL KORONA M14 40 mm is designed for dry drilling with M14-threaded angle grinders and compatible rotary tools. The 40 mm cutting diameter and diamond-segmented rim allow precise coring and hole cutting in hard materials such as ceramic tile, porcelain, glazed surfaces and natural stone without the need for liquid coolant. The bit is intended for tasks that require clean, accurate circular openings where water cooling is impractical or unavailable.
Advantages
The diamond rim provides efficient material removal and a long service life when used as recommended. Threaded M14 connection ensures secure mounting on standard angle grinders and compatible rotary tools, giving steady operation and reduced run-out. Its dry-cut design eliminates the need to manage water on job sites and reduces downtime associated with setting up wet-drilling systems. The 40 mm diameter offers a common size for pipe penetrations, outlet boxes and fixture holes in tiling and stonework.
Suitable for
Cutting circular holes in ceramic and porcelain tiles
Creating openings in natural stone and glazed surfaces
Renovation work where water use is restricted or impractical
Installing pipes, electrical boxes and fixtures through tiled surfaces
Key specifications
Cutting diameter: 40 mm
Connection type: M14 threaded shank for angle grinders and rotary tools
Drilling method: dry drilling (no coolant required)
Cutting edge: diamond-segmented rim suitable for hard, brittle materials
Typical applications: tile, porcelain, ceramic, glazed surfaces, natural stone
How to use
Securely attach the drill bit to an M14-compatible angle grinder or rotary tool following the tool manufacturer's instructions. Mark the center of the hole on the workpiece and start drilling at low speed to create a guide groove. Apply steady, moderate pressure and maintain a perpendicular angle to the surface; increase speed as the rim establishes contact. Periodically lift the tool slightly to remove dust and allow cooling by air flow. Do not force the bit; allow the diamond segments to cut at their effective rate. After completing the hole, inspect the edge and remove any remaining debris with a soft brush.
Usage recommendations
Use eye, respiratory and hearing protection, and secure workpieces before drilling. For best results with porcelain and very hard natural stone, use light, consistent pressure and avoid prolonged continuous contact to prevent overheating. If possible, intermittently cool the cutting area with a small airflow or pauses to extend bit life. Replace the bit if excessive wear reduces cutting efficiency or if segments become damaged.
