Porcelain and vitrified tile
The primary application. Vitrified bodies are dense and hard — use a harder bond, keep the water flowing and let the blade cut at its own rate.

Porcelain & Tile Cutting Blade
Thin-kerf diamond blades for porcelain, ceramic tile and vitrified slabs — continuous rim, low segment height and a fine diamond bond that leaves a clean glaze edge instead of a chipped one.
Tile does not wear a blade out; it chips. Chipping comes from a blade that is too thick for the glaze, a feed rate that is too fast, or a rim that cannot clear the swarf. A thin continuous rim run at low feed is what produces a factory-clean edge. Hubei Qianzhao Diamond Tools Co., Ltd (Ezhou, Hubei) produces 100,000 blades and 3 million segments a year and exports to 14 countries.

Overview
Why does porcelain chip when I cut it?
Porcelain chips for three reasons: the blade is thicker than the glaze can tolerate, the feed rate is too high, or the rim cannot clear the swarf fast enough. Fix the blade first, then the technique.
| What you are cutting | What to ask for |
|---|---|
| Glazed wall tile, soft body | Thin continuous rim, fine bond — the glaze is the only hard part |
| Porcelain and vitrified tile | Harder bond and finer diamond; expect slower feed and more water |
| Large-format slab, 6 mm and up | Rigid thin core to stop deflection at the end of the cut |
| Cut-outs, L-shapes, drain holes | Small diameter with continuous rim — a corner is where chipping starts |
A tile blade and a stone blade are not interchangeable. Tile blades use a continuous rim with no gullets, because a segmented rim grabs the glaze and lifts it. Run a granite blade on porcelain and you will see chipping along the whole cut, no matter how slow you go.

Full series
Which diameter do I need for which cutter?
The machine decides the diameter. All sizes use a continuous rim; the bore and rim height change with the machine.
| Diameter | Inch | Typical machine | Typical job |
|---|---|---|---|
| 100 mm | 4" | Angle grinder | Small format tile, cut-outs, repair work |
| 115 mm | 4.5" | Angle grinder | Wall and floor tile, straight cuts |
| 125 mm | 5" | Angle grinder | Floor tile, thin slab |
| 180 mm | 7" | Angle grinder / small cutter | Large tile, deeper cut |
| 230 mm | 9" | Angle grinder | Large-format tile, slab work |
| 350 mm | 14" | Bench / hand-held wet cutter | Full slab, repetitive straight cuts |
Rim height, core thickness and maximum rpm are set per diameter and confirmed on the quotation. Never exceed the maximum rpm printed on the blade.

Applications
Which tiles can these blades cut?
Built for tile and porcelain on grinders and wet cutters. Selection should account for the tile body, the glaze and whether the cut is a straight run or a cut-out.
Glazed wall and floor tile
Softer body, hard glaze. A thin continuous rim enters the glaze without lifting it, which is where chipping normally starts.
Large-format slab and cut-outs
A rigid thin core stops the blade deflecting at the end of a long cut. For L-shapes and drain holes, use a small diameter and finish the corner from both sides.
06
Customization
Can the logo and packaging be customized?
Logo
Laser-marked or printed logo on the core, matching the artwork you supply. Size and placement confirmed against the blade diameter.
Packaging
Skin packaging, colour boxes and neutral export cartons — including cartons with no branding for distributors.
Specification
Bore, rim height and bond can be set for a specific tile body or machine, subject to a minimum order quantity per specification.

Manufacturing
What is Hubei Qianzhao's manufacturing capability?
Qianzhao has been making diamond tools in Ezhou, Hubei for seven years. The plant produces 100,000 blades and 3 million diamond segments a year, and exports to 14 countries.
Continuous rims are produced in-house, which is what makes a fine, even diamond distribution possible at the edge — the part of the blade that decides whether the glaze chips.
08
FAQ
What should I confirm before ordering a tile blade?
Why does my tile blade chip the edge?
Almost always because the blade is too thick for the glaze, or the feed rate is too high. A segmented rim designed for stone grabs the glaze and lifts it. Switch to a thin continuous rim, reduce the feed, and keep water on the cut.
Wet or dry for porcelain?
Dry is normal on an angle grinder, but water gives a cleaner edge and much longer blade life. On a bench or bridge cutter always run wet — dry cutting a large slab overheats the rim and warps the core.
What bore do the tile blades come with?
22.23 mm as standard, which fits angle grinders. 25.4 mm and other bores, plus reducing rings, can be supplied — state the arbor when you inquire.
Can I use a tile blade on marble or granite?
It will cut, but the bond is designed for a hard, thin, brittle body, not for thick stone. On granite the blade will glaze and slow down quickly. Use a stone blade for stone.
What is the minimum order quantity?
10 pieces per size for stock specifications. Mixed sizes can be combined in one order.
