Diamond core bit RUBI Easy Gres 120 mm — wet cutting, model 5982

RUBI Easy Gres 120 mm diamond core bit (model 5982) is a wet-cutting drill accessory designed for precision drilling in hard ceramic and gres porcelain. The tool is manufactured for use with water cooling to control temperature and remove debris, which helps maintain cutting performance and extend abrasive life. Its 120 mm diameter makes it suitable for creating holes for pipes, fixtures and electrical installations when working with dense tile and porcelain materials.

Advantages

The diamond-segment edge provides consistent cutting speed and lifetime when used with adequate water supply. Wet cutting reduces heat generation and dust, improving hole quality and minimizing chipping on brittle gres porcelain. The core bit is balanced for rotational stability, allowing cleaner circular cuts when mounted on compatible angle grinders or core drilling rigs. Its construction focuses on durability for repeated use in installation and plumbing applications.

Suitable for

• Drilling through hard ceramic tiles and gres porcelain
• Creating holes for plumbing fixtures and pipes
• Installing electrical boxes or conduit through tiled surfaces
• Professional tiling and renovation projects requiring precise circular cuts

Key specifications

• Diameter: 120 mm
• Cutting method: wet cutting
• Material target: hard ceramic, gres porcelain
• Application: angle grinders and core drill rigs that support wet cutting
• Segment type: diamond-segment edge for improved cutting and wear resistance

How to use

Mount the core bit on a compatible arbor or drill rig according to the tool manufacturer's instructions. Ensure the workpiece is secured and that water feed for wet cutting is set up to provide continuous cooling and flushing of slurry. Start drilling at low to moderate speed to establish the cut, then apply steady, even pressure while maintaining water flow. Avoid excessive side forces or high feed rates that can cause binding or premature wear. After cutting, stop the tool, allow the bit to cool in water if necessary, and clean debris from the segments before storage.

Usage recommendations

Use consistent water supply during operation to maximize diamond segment life and hole quality. Select appropriate rotational speed and a stable mounting system to reduce vibration and prevent chipping. Inspect the bit for wear and cracks before each use and replace when diamond segments are significantly worn.
