Integra Tools Platinum Series Blades P4DIA2.5 Semi-Round Flush Cut Universal Oscillating 2-1/2" Diamond Grout Saw Blade (4-Items)

I was re-grouting a shower floor tile and was using these on a dewalt multi tool. I find this half circle model doesn't stick out very far so it has limited use. The much better ones are the sling style ones.

Used on my Fein Multimaster. Worked great! Made fast work of my grout, no damage to tiles. The power tool you use matters as much as the cutting tool, I would only recommend Fein.

These blades aren't as thin as others and dulled relatively easily when using to remove grout. They did however work fine when cutting through glazed porcelain tile in the shower. I'd recommend them for a small one-time job.

Great for small areas of grout removal. I've used this in showers and floors. Keep control of your tool. If it runs off onto the surface it will remove glaze or mar the surface quickly.

Used these when doing ceramic tile. Worked well.

Great product for the price and quick delivery.

seemed like a good deal
