Diamond Core Drill Bit INDIAN PROFESSIONAL KORONA DIAMENTOWA M14 14 mm — dry drilling

Diamond core drill bit INDIAN PROFESSIONAL KORONA DIAMENTOWA M14 14 mm is a compact, precision cutting tool intended for dry drilling through hard materials. With a 14 mm cutting diameter and M14 thread, this core bit is designed for tasks that require small, accurate holes where diamond cutting edges provide improved wear resistance and cutting performance. It is suitable for use on materials such as ceramic, porcelain, natural stone and other dense substrates where conventional bits can wear quickly.

Advantages

The diamond cutting edge ensures consistent cutting performance and extended service life compared with standard carbide bits when used on hard, abrasive surfaces. Its M14 mounting thread provides compatibility with a wide range of angle grinders and drilling adapters that accept M14 accessories, enabling easy installation and stable operation. The 14 mm diameter offers a compact solution for precise anchor holes, conduit entry points and sample extraction with minimal material removal.

Suitable for

• Drilling small-diameter holes for anchors and fasteners
• Creating passages for electrical conduits and piping
• Precision holes in ceramic and porcelain tiles
• Small core sampling and on-site material testing

Key specifications

• Cutting diameter: 14 mm
• Thread type: M14
• Drilling method: dry drilling
• Cutting edge material: diamond grit
• Intended use: hard, dense materials (ceramic, stone, porcelain)

How to use

Secure the core bit into a compatible M14 tool or adapter according to the tool manufacturer's instructions. Mark the drilling location and ensure the workpiece is stable and supported. Start drilling at low speed to establish the cutting groove, then apply steady, moderate pressure while maintaining the tool perpendicular to the surface. Because this bit is designed for dry drilling, avoid continuous heavy pressure and allow intermittent pauses to prevent overheating; follow the tool's duty cycle recommendations.

Usage recommendations

Use appropriate personal protective equipment including eye and respiratory protection. For improved hole quality and longer bit life, consider periodic short cooling pauses and clear debris from the hole frequently. Ensure the drill and adapter are rated for dry diamond drilling and match rotational speed recommendations for a 14 mm diamond core bit.
