The J-SLOT – CPJ dry cutting diamond blade by RUBI for porcelain tiles is specially designed to offer the tile fixing professional the best performance.

The CPJ diamond blade is particularly recommended for straight cuts in porcelain tiles and especially in those jobs requiring a high cutting speed without sacrificing high levels of performance and quality.

Because of its reduced thickness, the CPJ diamond blade by RUBI is not recommended for mitre cuts.

The use of dry cutting diamond blades with grinders is a very demanding job, both for the material and for the blade, and of course for the user.

For these reasons and because of its J-SLOT type, the CPJ blade by RUBI increases the cutting speed in very hard porcelain tiles, while reducing the stresses generated during cutting.

Thus, both speed and performance are ensured and straight cuts in porcelain tiles are made considerably easier.

By means of laser welding, we have made the joint between the diamond rim and the steel core of the RUBI CPJ blade a guarantee of quality and safety for the user.

Within its range of diamond blades, RUBI offers professionals two blade classes: PRO and SUPERPRO.

The PRO blades offer the professional user the best price-performance ratio.

SUPERPRO blades are the best choice for the most demanding jobs.

Blades with thicknesses of less than 2 mm are not suitable for mitre cuts.

This range of accessories, like the other ranges in our catalogue, is designed to offer users time savings and increase the efficiency in their work. At RUBI we are aware of the importance today of efficiency and time savings, so our product development managers are very focused on these concepts when designing new tools.
