Diamond cutting wheel set RUBI TCR with DRYGRES drill bits (model 68923)

The RUBI TCR diamond cutting wheel set with DRYGRES drill bits (model 68923) is a combined accessory kit designed for dry cutting and drilling in ceramic, porcelain and natural stone. The set brings together thin TCR diamond cutting discs for accurate cuts and DRYGRES drill bits optimized for dry drilling, enabling cutting, corner trimming and hole-making tasks without water cooling. This kit is intended for use with angle grinders and electric drills where dry operation is required or preferred.

Advantages

The TCR diamond cutting wheels deliver precise, low-chipping cuts on glazed and unglazed tiles thanks to a controlled diamond bond and reduced cutting width. DRYGRES drill bits are engineered for effective dry drilling in hard ceramics and porcelain with improved dust evacuation. Together, the components provide a compact solution for combined cutting and drilling workflows, reducing the need to change tools frequently and enabling faster on-site adjustments.

Suitable for

• Cutting ceramic and porcelain tiles with an angle grinder
• Performing corner cuts and trimming around fixtures
• Dry drilling holes in ceramic, porcelain and natural stone for fittings
• Professional tilers and DIY tiling projects

Key specifications

• Application: dry cutting and dry drilling for tile and stone work
• Cutting discs: thin diamond TCR type for reduced chipping and narrow kerf
• Drill bits: DRYGRES design optimized for hard ceramics and porcelain
• Suitable tools: angle grinders for cutting, electric drills for drilling
• Materials: glazed ceramic, porcelain stoneware and natural stone

How to use

Fit the appropriate TCR diamond cutting disc to a compatible angle grinder and secure according to the tool manufacturer's instructions. Mark the cut line on the tile and make steady, controlled passes to minimize chipping; avoid forcing the wheel and allow the disc to cut at its own rate. For drilling, mount the DRYGRES drill bit in an appropriate drill chuck, start at low speed to establish the initial point and then increase speed within the drill and bit manufacturer's recommended range. Use intermittent operation and light pressure to prevent overheating and to allow dust to clear from the drilling site.

Recommendations

Wear appropriate personal protective equipment including eye protection, dust mask and hearing protection. Ensure adequate dust extraction or local ventilation when performing dry cutting and drilling. Do not use diamond cutting discs or drill bits beyond their intended material range. Check tool rpm compatibility and follow the safety instructions of the power tool manufacturer.
