Diamond cutting disc RUBI CPR 125 SUPERPRO 125 mm × 22.2 mm for tile and masonry cutting

RUBI CPR 125 SUPERPRO 125 mm × 22.2 mm is a diamond cutting disc engineered for precise cutting of ceramic tiles, natural stone and masonry. The disc has a 125 mm diameter and a 22.2 mm bore and features a continuous rim with diamond segments optimized for both wet and dry cutting. Designed to work on angle grinders and tile saws, the CPR 125 SUPERPRO delivers controlled cuts and clean edges for professional tiling and general construction tasks.

Advantages

The continuous rim design minimizes chipping and produces smooth edges on fragile materials such as glazed tiles and porcelain. Diamond-impregnated segments provide fast cutting speed while maintaining durability across repeated use. The disc is compatible with common 125 mm machines and enables both wet and dry operation, offering flexibility on the job site. Its balanced construction reduces vibration for improved cutting control and accuracy.

How to use

Mount the disc securely on a compatible 125 mm angle grinder or tile saw with a 22.2 mm arbor. Follow the machine manufacturer’s instructions for fastening and safety. For dry cutting, use steady, moderate feed rates and allow the disc to cool periodically to avoid overheating. For wet cutting, ensure an even water supply to the cutting zone to reduce dust and extend blade life. Keep both hands on the tool, use appropriate guards, and wear protective equipment such as eye protection, gloves and a dust mask.

Usage recommendations

For best results on porcelain and glazed tiles use light, controlled passes rather than forcing the disc. Use wet cutting when possible to prolong segment life and reduce airborne dust. Inspect the disc before each use and replace it if signs of uneven wear, cracking or missing segments are found.
