On modern tiling and cladding jobsites the “one-size-fits-all” blade is a relic of the past. With the evolution of materials — ranging from glass mosaics and Dekton® slabs to high-thickness porcelain stoneware — using the wrong tool means wasting time and ruining expensive materials.
In this guide, we compare Ghelfi’s new precision specialist, the Champions HP, with other solutions in the Ghelfi range for angle grinders.
Champions HP – High Precision Gres : “The Surgeon”
If aesthetic perfection of the edge is your top priority, this is your tool.
-
Identikit: Ultra-thin 1.1 mm thickness with a reinforced core.
-
Ideal Use: Visible cuts on porcelain stoneware and glazed tiles where no chipping is allowed, or where surface pattern continuity is essential.
-
The Advantage: It is the “gentlest” blade on the material, making it ideal for cordless grinders due to minimal friction.
Champions DK – Turbo Dekton : The Heavy Dury Specialist
Sintered materials and ultra-compact surfaces require a specific diamond formula.
-
Identikit: Special bond designed for extreme hardness.
-
Ideal Use: Dekton®, Lapitec®, and high-density porcelain stoneware.
-
Why Choose It: Standard blades often “glaze over” (stop cutting) on these materials. The DK keeps biting even on the hardest surfaces on the market.
Champions TX – Turbo Extrapiuma : “The Sprinter”
The favorite for installers who need to cover many linear meters without sacrificing quality.
-
Identikit: Turbo rim for rapid cooling and high material removal.
-
Ideal Use: Universal cutting of porcelain stoneware, hard ceramics, and klinker.
-
Why Choose It: It’s faster than the HP model. If you have a large volume of material to cut and speed is your priority, the Extrapiuma is unbeatable.
Champions CX – Continuous Rim Extra Fine : “The Jeweler”
Glass, mosaic, and thin glazes need a touch, not a bite.
-
Identikit: Extra-fine continuous rim designed for maximum delicacy.
-
Ideal Use: Glass mosaic, ultra-thin ceramics, vitreous materials.
-
Why Choose It: Where even the HP might be too aggressive, the CX guarantees zero micro-chipping on the most fragile materials.
Base CC – Universal Continuous Rim : “The Reliable Ally”
The professional “entry-level” solution for daily tasks.
-
Identikit: Standard continuous rim blade.
-
Ideal Use: Traditional ceramics, double-fired tiles, and standard stoneware for non-visible cuts.
-
Why Choose It: Exceptional value for money for those seeking a robust blade for routine work where extreme precision or speed isn’t the primary requirement.
Champions JO – Cut & Miter : “The 45° Specialist”
Executing a 45-degree miter cut requires a blade that won’t flex.
-
Identikit: A blade with a much stiffer and thicker steel core.
-
Ideal Use: Specialized for angled cuts and creating sharp corners.
-
Why Choose It: Unlike the HP or TX, this blade does not “waver” when tilted, ensuring a straight and consistent miter along the entire length of the tile.
Multipurpose Diamond PD : “The All-Rounder”
More than just a blade, it’s a cutting and finishing system.
-
Identikit: Diamond blade with diamond coating also applied to the side surface. Available in two grits.
-
Ideal Use: Cutting + Grinding. Perfect for shaping curves or refining irregular edges.
-
Why Choose It: If you need to make a cut and then round the edge or fix a chip, you don’t have to switch tools on your grinder.
