Our take on the Diablo 4-1/2 in. D X 7/8 in. Silicon Carbide Masonry Circular Cut-Off Disc

This is a 4-1/2 in. silicon carbide cut-off disc with a 7/8 in. arbor and a 1/4 in. thick edge, made by Diablo for cutting masonry with an angle grinder. Silicon carbide is the abrasive of choice for brick, block, concrete and stone, where aluminum oxide discs wear fast. The thick 1/4 in. body favors straight, burr-free cuts over speed, so it suits general masonry work rather than fast, thin-kerf slicing. It is a single disc, so plan on spares for bigger jobs.

Best forCutting brick, block and concrete with an angle grinderMasons and remodelers who want clean, straight cutsOccasional masonry work around the house
Pros
  • Silicon carbide abrasive holds up on masonry better than aluminum oxide
  • 1/4 in. thickness gives a stiff disc that cuts straight
  • Standard 7/8 in. arbor fits most 4-1/2 in. angle grinders
  • Diablo's carbide abrasives have a solid reputation among tradespeople
Cons
  • Thick 1/4 in. kerf removes more material and cuts slower than thin discs
  • Silicon carbide is brittle and can chip if the disc is dropped or jammed
  • Sold as a single disc, so heavy users need to stock spares
  • Not for metal, despite some listings grouping it with metal-cutting blades

Questions and answers

Will this fit my 4-1/2 in. angle grinder?
It has a 4-1/2 in. diameter and a 7/8 in. arbor, the standard size for most 4-1/2 in. angle grinders. Check that your grinder's spindle and guard accept a 7/8 in. arbor disc.
Can I cut metal with it?
No. It is a silicon carbide masonry disc meant for brick, block, concrete and stone. Use an abrasive metal cut-off disc for steel and other metals.
How is it different from a diamond blade?
Diamond blades cut faster and last far longer in masonry but usually cost much more. Silicon carbide discs like this one are the lower-cost option for occasional cutting and general masonry work.
Why is it 1/4 in. thick?
The thick body makes the disc stiff, which helps it track straight and resist flexing in a cut. The trade-off is a wider kerf and slower cutting than a thin disc.
What comes in the box?
One cut-off disc. No flange, nut or wrench is included, so use the hardware that came with your grinder.
Where is the Diablo 4-1/2 in. D X 7/8 in. Silicon Carbide Masonry Circular Cut-Off Disc cheapest?
