Dart Red 10 PRO ST-10 Super Thin Porcelain Tile Cutting Blade

The Dart Red 10 PRO ST-10 is a super-thin porcelain tile cutting blade built for tradespeople who need clean, fast results on hard tile materials. Porcelain is notoriously unforgiving — too much pressure or the wrong blade and you get chipping, cracking, or a finish that needs grinding back. This blade is designed specifically to avoid all of that. The ultra-thin kerf reduces friction, keeps heat down, and lets the diamond segment do the work rather than brute-forcing through the material.

The ST-10 designation refers to the super-thin body profile combined with a 10mm segment height. That segment height is a practical detail worth noting: a taller segment means more usable diamond, which extends blade life and keeps performance consistent as the blade wears. You get more cuts per blade before the performance starts to fall off, which matters when you are pricing jobs and ordering materials.

Where the Dart Red 10 PRO Porcelain Tile Cutting Blade Performs

This blade handles full-body porcelain, glazed ceramic, and marble with equal confidence. Full-body porcelain is one of the toughest materials a tiler encounters — it is dense, abrasive, and shows up any imperfection in the cut edge immediately. The Dart PRO ST-10 is designed to cut through this material cleanly, producing a tight, chip-free edge that needs minimal dressing before grouting.

The blade is available in four diameters: 100mm, 115mm, 125mm, and 300mm. The smaller sizes suit angle grinders used for detail cuts, trimming around pipework, or cutting floor tiles in situ. The 300mm blade fits a tile saw or bench-mounted wet saw and handles larger format floor tiles and wall tiles where you need a full straight run. Having the right diameter for the tool you are using is half the battle — undersizing or adapting the wrong blade wastes time and wears the blade unevenly.

Wet or Dry Cutting

The Dart Red 10 PRO ST-10 is suitable for both wet and dry cutting, which gives it real flexibility on site. Wet cutting on a bench saw gives the cleanest finish and longest blade life. Dry cutting with an angle grinder is fine for shorter runs, though it is worth keeping cuts brief and allowing cooling time between passes — heat is the enemy of any diamond blade, and porcelain generates more of it than softer tile materials.

The blade fits standard arbors across the size range: 16mm bore on the 100mm blade and 22mm bore on the 115mm and 125mm versions, with a 20mm bore on the 300mm. Check your tool’s spindle size before ordering — it takes about ten seconds and saves a wasted delivery.

For tilers, builders, and floor layers who cut porcelain regularly, a blade that holds its edge and cuts cleanly is not a luxury, it is the baseline. The Dart Red 10 PRO ST-10 meets that standard at a price that makes stocking a spare a straightforward decision.
