BoschDBX4541E 4-1/2 In. X-LOCK Segmented Rim Diamond Blade Xtreme Compatible with 7/8 In. Arbor for Application in Reinforced Concrete, Brick, Stone

The locking system is just so cool, and so easy to use it's one of the utmost desirable features that make the system so enjoyable to use. Tool-less replacement of a wheel is such a great feature. The quality of the discs is top-notch, and the ease of cutting is guaranteed by the high quality of the embedded diamond fragments.

Tiled for the first time, and this with my Bosch cordless angle grinder was by far the easiest and best way to cut the tiles.

Ordered two discs since I did not know the lifespan of the product. Second disc not needed but for the price, I will keep. Pleasantly surprised with its longevity to cut thru curbing! Highly recommend this product.

This blade has cut multiple 12x24 tiles into smaller parts to make a better looking (smaller random sized block) surface. I have only used it dry cutting. It still cuts very well after perhaps 100 linear feet of cuts through ceramic tile. It is dusty work so plan on cleanup. I actually set up a cutting surface over the small dumpster and eliminated most of the cleanup. I had to clean the tile, my hands, and of course the cutoff tool. The blade still seems to be like new, so I don't know how long it will last. It has completed this project so I am very satisfied with the quality of the blade.I was going to buy a tile saw, but when I went to the box store, they didn't have any (pandemic related shortages... plenty of toilet paper, but no tile saws). I opted for a cutoff saw that had a special going and am very glad that I did. It was much easier than setting up a saw, running water, and cleaning up the wet mess. The X lock blade is a very easy process, much better than using a wrench to remove and tighten the blade. If I ever need another one of these, I will not hesitate to get this brand again.

Cut grooves to tuck my chimney flashing great blade

Dry cuts extremely well. Quick change is sooo easy.

Sealing driveway cracks, this blade cleaned/opened them up super fast. really impressed.

excelente calidad y durabilidad

to cutting ceramic to concrete this blade can take a lot of abuse and still cut nice and clean.

el precio están muy alto con respecto a la entrada normal, el costo beneficio se queda un poco atrás por el precio, a pesar de la rapidez por el cambio.

Wie fast alle Produkte von Bosch ist es super.

Good blade. They're a bit confusing if you're just using X-Lock for the first time as they are installed with the sticker facing towards the grinder rather than out, which is how I've always put them on regular grinders.

Wanted to replace a sink sitting on top of a ceramic counter top and this made my job so easy. It cuts through the ceramic like butter.It doesn’t look damaged and chipped and I look forward to the next usage.It also feels very secured once mounted.
