RDXMAX ® 125mm Diamond Cutting Discs for Angle Grinder - Super Thin Fast, Clean Cut on Porcelain, Granite, Marble, Concrete, Tiles, Stones, Bricks & Ceramics- 4.5" Wheel - Size 125 x 1.4 x 22.23mm

The cut quality is good and quick. I've never had one of these diamond blades before. I bought it to cut concrete blocks . I have no idea how long it will last, but I'm happy so far after 5 courses. Very reasonable price.

I use it for cutting tiles at work it’s so smooth leaves no chips and seems to last forever great buy

Very good disc cutter, cut's tiles very good.

I have some thick floor tiles to cut in place. I went through several others disks, tile drill bits, masonry bits, supposedly diamond coated disks and so on and these tiles defeated them all. But This disk went through with ease! There is nothing on the package about using water but I kept the disk cool by spraying water in it during the process and at the end there is barely any visible wear! This has been worth the money for one single job but will last many more clearly.

Cuts through 20mm porcelain slabs so easily. Have done 10 slabs and length of cut was 900mmIts still just as sharp as the first cut.

Been using the same disc throughout a long term paving project, still cutting as well as it did on the first cut, supplier recommended.

Caution when they get worn they explode

Been using this for a while now and it seems to last forever, well worth the money
