Most diamond blades incorporate cutaway segments which aid the aerodynamics and cutting speed, but continuous rim blades are required when cutting porcelain and ceramic tiles.
The continuous rim offers a smoother cut because the surface impact is consistent. Although many manufactured tiles are developed with increased hardness, they are still as brittle as you would expect porcelain to be. Therefore, a cutting action that minimises vibration is required.
Diamond Blades For Ceramic Tiles
Norton Clipper have been pioneers of laser-welded diamond blades for decades, and their Extreme Ceram Turbo (formerly known as Extreme Gres XT) blade is specifically aimed at cutting tiles. Whilst many diamond blades can be 2-3mm in width, the Extreme Ceram Turbo is just 1.4mm thick. This thinner profile results in a finer cut, which in turn means less material wastage and more accuracy.
In line with Clipper’s new diamond ratings system, the Extreme label means that it is suitable for the biggest projects and the extra durability increases efficiency. In the mid-long term a longer lasting blade becomes better value than a lower-cost alternative when you consider how many times it will need replacing.
Another feature inherent in the design of the Turbo Blades from Norton Clipper is the circular slots in the blade core. These facilitate a faster blade action by reducing weight but maintaining strength where it is needed. The higher frequency of the blade ensures a cleaner cut into the tile.
Continuous rim blades can be used for hand cutters or grinders, but the accuracy required for cutting tiles warrants a guided cut that is best achieved from a tile saw or rail saw. The blades we mention in this article are suitable for wet and dry cutting, but we would generally recommend using a water feed because this prolongs the life of the blade.
