BOSCH DB4542C 4-1/2 in. Premium Turbo Rim Diamond Blade with 5/8 in., 7/8 in. Arbor for Smooth Cut Wet/Dry Cutting Applications in Stone, Concrete, Brick

I searched a long time to find a 4.5 inch angle grinder blade to use with my new angle grinder. I needed a blade with a 5/8" spindle that would work for landscape bricks. We were building a landscape wall and the top cap bricks (which were 2" thick) needed to be cut so they would fit together cleanly. This blade has a 5/8" spindle hole that can be converted to 20mm or 7/8" to fit your particular grinder. I was extremely surprised at how well this blade finished the rough cuts I made with the chisel and ended up using it to score the brick all the way around before cutting it with the chisel. The blade edge would cut like butter to about 1/2" deep, but would take a bit more work to go deeper. I won't knock the blade for that as I don't think it's intended to be used for long deep cuts, but rather shallow cuts and grinding. All-in-all, this blade worked much better than expected for its intended purpose and the life seems good. I cut about 30 bricks (again, scoring all the way around which was about 16"-20" per brick) and this blade didn't show any signs of slowing down by the last brick. I'm very pleased.

Typically I run 14” blades on granite but needed a smaller blade for a patio. This blade worked great on both 2” granite slabs and 2.5” concrete unit pavers. This will be my go to small blade.

This blade cuts great and seems durable. I made a cutout for my kitchen sink in 1" thick granite. The blade cut great start to finish. If you ever cut granite indoors make a tent to contain the dust. I did not and had to hire a cleaning crew to deep clean the how. The dust was even upstair after having made the cuts downstairs. Please use this blade safely. I recommend a 5" blade for 1" granite.

Great blade for cutting granite countertops. Keys to success are: lots of water, don't go fast, GFCI and if you are creating dust, you don't have enough water.

I needed this to cut a hole in porcelain tile for a shower remodel. It did a fantastic job. Used it for several other cuts.

I Love Bosch tools and this does the trick for masonry cutting of all sorts but Im not sure how long it'll last. This is their base model blade as they make a better and more expensive one. But for a weekender this is great and the price cant be beat.

Good price for Bosch

Highly recommend for cutting porcelain tile, such as cutouts for electrical sockets.
