Bosch1x PRO Multi Material Long Life Diamond Cutting Disc for Bore 22.23 and Small Angle Grinders (for Concrete, Reinforced concrete, Ø 125 mm, Professional Accessory Small Angle Grinder)

Used to cut 8" thick concrete (not in one go! To the max depth possible with my grinder).Really clean cut, cut the concrete like I was slicing bread. I used with a Ryobi 18v angle grinder.Still sharp after use and minimal wear, I cut around 7m or so.

These angle grinder cutting discs worked well and cut through concrete paving slabs relatively easily. Because the depth of cut is low, it was necessary to turn the slab over to complete the cut.

Fantastic! I didn't use my old disc cutter much because it didn't cut cleanly but this disc changed all that.From roof tiles to resin worktops it's like a knife through butter and still just as good as on day 1 after a lot of hard work.Very impressed.

I used this to on my angle grinder to cut a reinforced concrete gravel board. It did the job incredibly well. Not a knife through butter, but a fast, clean cut. The disc isn't wide enough to cut through the board in one go, so you cut first through one side then flip the board over to cut the other half, but this is no problem. The clouds of concrete dusk (wear goggles and mask!) tell everyone you're doing a great job!Stayed sharp cutting through 2 boards. I think it will do a few more.

Gave it 4 because blade wear’s quickly but very good quality!

Works well no complaints.

Excellent

When used on wet stone it's cuts like a hot knife through butter. By making a double pass I was able to cut curves so we could replace broken slabs from the outside of a stone circle.
