I used it on a Bosch grinder to shave off a little of concrete floor in my basement project. very good product. I am a new first time user I wont have comparison to say if its the best, but I got good results.
excellent tool. Quite comfortable in your hand and very powerful. I used it for shaving off some concrete floor using Dewalt grinding wheel and then I used it for cutting ceramic tiles. I used Bosch DB4543S tile cutting blade to cut the ceramic tiles. I am highly impressed and happy I got this tool, and know this I am first time user. I will recommend this to anyone, worth it.
