Diamond Blades for Ceramic Tiles

Tyrolit and Nozar diamond blades for ceramic tiles — how diamond cutting works

A diamond blade for ceramic tiles cuts by abrasion, not by classic blade-edge cutting: a working rim of sintered diamond grains set in a metal bond called a matrix sits around the edge of a steel core. The exposed diamond crystals grind away particles of the hard, glazed surface, and as grains wear out they break away to expose fresh ones underneath — which is why the blade never dulls the way a saw blade does. The maximum circumferential speed of a diamond blade is usually around 80 m/s, which caps a Ø 125 mm blade at roughly 12,200 rpm and a Ø 230 mm blade at roughly 6,600 rpm.

At NORWIT.PL we stock diamond blades for ceramic tiles and porcelain stoneware primarily from Tyrolit, plus Nozar (Nozar) — in continuous-rim and turbo-rim versions, in sizes from Ø 110 to 300 mm. This category is part of the diamond blades department. Below we explain how to match rim type, diameter and mounting bore to the material and to your cutting machine.

Types of blades for tiles and porcelain stoneware — continuous, turbo and segmented rim

Cut quality and edge durability on a tile depend on the shape of the rim. A continuous rim has a smooth, unbroken diamond edge — it cuts most finely and does not chip a glazed surface, which makes it the default choice for wall tiles and angled cuts. A turbo rim has a wavy edge with cooling channels — it cuts faster at the cost of a slightly rougher edge, so it suits hard technical porcelain stoneware and clinker. A segmented rim, with gaps between diamond segments, is built for concrete, brick and building stone — on tiles it leaves a ragged edge and is not recommended here.

Blades for materials other than ceramic cladding — segmented blades for concrete, brick and stone — are in the parent diamond blades category, together with blades for fresh concrete and asphalt.

Choosing blade diameter (Ø) and mounting bore for your cutter

Blade diameter is matched to the maximum size allowed by the cutting machine, and the mounting bore to the machine's spindle. The most common bores are 22.2 mm (angle grinders, hand-held tile cutters) and 25.4 mm (tile saws); a reducing ring bridges a mismatch between the two.

An oversized blade can exceed the machine's maximum allowable circumferential speed, so size is always checked against the cutter's manual, not just against the mounting bore.

Wet or dry cutting and matching the blade to the material

Ceramic tile (terracotta, wall tile) has a soft, glazed surface — a fine-grit continuous rim is enough for it. Porcelain stoneware, fired at up to around 1,200°C, has a dense structure (water absorption below 0.5%) with hardness close to granite and needs a continuous or turbo rim with a harder bond, while clinker — more abrasive and coarser-grained — responds best to a turbo rim, which sheds heat faster during longer cuts.

Wet cutting, with a steady flow of water cooling the rim, gives a cleaner edge and binds dust instead of releasing it into the air — the standard method on tile and porcelain stoneware saws. Dry cutting with an angle grinder suits short, on-site cuts, but needs a break every 20–30 seconds of work to avoid overheating the diamond segment above around 600°C, which shortens its life and can separate the bond from the core. Universal Tyrolit and Nozar blades can be used with both methods unless the label states otherwise.
