Best Diamond Tip Blade for Angle Grinder (2026): 5 Blades Compared

The tile job waits on a grinder that can cut a straight line through porcelain without chipping the glaze, and the metal job waits on a disc that can bite rebar without shattering. A diamond tip blade turns a standard angle grinder into a cutter for tile, stone, metal and masonry, with a rim that stays sharp long after a bonded disc wears down. The best diamond tip blade for angle grinder is the one that matches the arbor, the material and the cut, wet or dry.

Compared on paper

Specs such as CFM, PSI and torque are the manufacturer’s ratings as listed, collected 11 November 2026. Three of the five state an arbor size; none states a warranty term.

How the points were given

The Shop Score weighs performance, build, value, safety and warranty, with the weights published on the How We Pick page. For a diamond blade, performance means material range, cutting life and stated RPM limits; build means rim design, body construction and stated thickness; safety means stated one-piece construction and shatter resistance. All five listings state a safety-relevant feature. No listing states a warranty term.

Shop Scores range from a low of 9.2 to a high of 9.8, with each tool positioned by its weighted points proportionally, and more points always yields a higher score.

What the listings tell you

Five diamond blades made the cut, all 4-1/2 in across. Four come in packs of 3 and one in a pack of 2. Three state a 7/8 in arbor, and one of those includes a 5/8 in adapter or bushing. Two state a 0.05 in cutting thickness, and one states a 13,300 RPM maximum. None states a warranty term.

How to choose the best diamond tip blade for angle grinder

Start with the material list

Material range decides whether one blade covers the job. The ONEGOTOOL cutting disc lists metals, steel bars, stainless steel, marble, ceramic tiles, stones and plastic pipes. The FOXBC blade lists rock slab, glass, cement, ceramic, stone, tile, granite, marble, slate, wood, metal and plastic. The LOZLIN blade lists marble, quartz, granite, stone, tile, metal and plastic. The EZARC blade lists ceramic and porcelain tile, and the ONEGOTOOL tile cutter lists porcelain, ceramic, glass and marble. For concrete work, see the best pressure washer nozzle for concrete.

Match the arbor and the thickness

Arbor fit decides whether the blade mounts at all. Three listings state a 7/8 in arbor: the ONEGOTOOL cutting disc, the FOXBC blade and the EZARC blade, with the FOXBC including a 5/8 in bushing and the EZARC including an adapter for a 5/8 in arbor. The LOZLIN blade states a 0.87 in arbor hole. The ONEGOTOOL tile cutter states no arbor size. Thickness runs thin here: the LOZLIN and ONEGOTOOL tile cutter blades state a 0.05 in cutting thickness, and the EZARC states a 1.2 mm segment thickness. A thin blade cuts a narrow kerf with less force.

Figures as stated in each listing; where a listing states nothing, the table says so.

Wet or dry, and the RPM limit

Wet and dry use decides how the blade cools. The FOXBC blade and the EZARC blade state dry and wet use, and the EZARC listing says wet cutting can significantly increase the life of the blade. The other three listings state no wet or dry guidance. RPM limits matter as much as fit: the EZARC blade states a 13,300 RPM maximum, and the other four listings state no RPM figure. Check the grinder speed against the blade maximum before mounting; see the best cordless angle grinder for the grinder itself.

Read the life claims as the maker states them

Life claims differ in kind, so read them as the maker states them. The ONEGOTOOL cutting disc claims it can cut steel bars more than 5,000 times, with a service life longer than that of 100 resin grinding wheels. The FOXBC blade claims up to 100X longer cutting life and durability when compared to one standard bonded cut-off disc. The other three listings make no life claim in numbers. Treat each figure as the maker's stated claim, and match the blade to the material rather than the claim.

Garage Fit Check

• Check the arbor before ordering: three listings state a 7/8 in arbor, the FOXBC with a 5/8 in bushing and the EZARC with an adapter for a 5/8 in arbor.
• Check the grinder speed: the EZARC blade states a 13,300 RPM maximum, and the other four listings state no RPM figure.
• Count the pack: three listings sell 3 pieces, the EZARC sells 2, and the ONEGOTOOL cutting disc lists 3 pieces.
• Plan water for wet cuts: the FOXBC and EZARC blades state dry and wet use, and wet cutting can significantly increase blade life, per the EZARC listing.
• Store the blades flat and dry.
