RUBI CPX‑200 PRO (30964) – J‑Slot Diamond Blade for Porcelain Tiles

High‑Speed Wet Cutting for Hard Porcelain Stoneware (Straight Cuts Only)

The RUBI CPX‑200 PRO (30964) J‑Slot diamond blade is engineered for high‑speed cutting of hard porcelain tiles, delivering excellent performance, stability and cutting quality for professional ceramic tile installers. Designed specifically for straight cuts, the CPX PRO excels in demanding porcelain applications where speed and precision are essential.

Product Overview

The CPX PRO features RUBI’s advanced J‑Slot rim design, which increases cutting speed while reducing internal stress and vibration during cutting. This makes it ideal for high‑hardness porcelain stoneware, where conventional blades often struggle.

Its thin rim allows for fast, fine cutting, but also means the blade is not suitable for mitre cuts. The CPX is optimised for wet cutting, ensuring cleaner edges, reduced friction and longer blade life.

The diamond band is laser‑welded to the steel core, ensuring maximum durability, safety and long‑term reliability—meeting the expectations of demanding tile‑laying professionals.
