Review on 🔹 XXGO 8-Pack Diamond Segment Swing Grit Grout Blades for Oscillating Multi Tool - XG8001S by James Broome

I bought these to cut precise holes in a plastered wall for repairs. (Plaster, cement mortar, concrete, and mortar are very similar materials in terms of the way they wear down the blades.) "Diamond" grit, if it's a real diamond, can adhere well to the edges , but the grit on the edge, which is the only bit that can be cut, wears out very quickly. It doesn't seem to matter what speed or pressure is applied to the oscillating tool. I've actually had better luck with branded carbide blades than these, which is pretty ridiculous considering carbide blades are supposed to be *much* less durable than anything "diamond" coated. I would skip this multipack and spend the same or more for less branded blades that you can at least easily return if they don't meet the manufacturer's specs.
