Cracking blade for the odd job with hard surfaces
I've had this for a few years. I used it to cut fibre cement board initially. It managed it but it was slow as time went on. Eventually, I used the bit to score it and then broke it along the line. I then cut a few tiles with it a few months later. Sailed through them. They were fairly soft glazed tiles. Most recently I used it to remove grout from the shower. I managed the whole shower and it did a really neat job. You probably would need to be careful if the tile was glazed/soft. Absolute cracker of a blade to have in the arsenal and no signs significant wear. Hopefully will last years more. Worth the outlay.

Not as Heavy Duty as Expected
Bought this for our DeWalt multicutter tool. Given it's for grout and it's a diamond cutter, thought it would cut through a light skim of interior render. I was disappointed with the performance. The blade wore out in 1 use. Won't be getting again
