Delta Diamond Boss Hog 4 1/2 Inch Turbo Premium Diamond Blade for Masonry, Brick, Block, Pavers, Concrete, Stone, Wet/Dry Cutting, Continuous Rim (4.5")

Very straightforward to use, it blew through the slate I needed to cut easily. No idea how long it will last, but it barely looked used. I used it in a Milwaukee 18V fuel brushless grinder.If you use this dry, don't forget your N95 mask because the rock dust is very plentiful!

I used this blade in my Harbor Freight Hercules Compound Miter Saw for cutting 12"x4"x8" retaining wall blocks. This blade makes very clean cuts without generating any heat. I was SHOCKED by the heat dissipation - the temperature of the blocks that I cut was unchanged - no residual heating whatsoever, blocks were cool to the touch. The only limitations were caused by the saw. It's expensive, so 3 stars. Can only give it a three stars for durability and longevity because I only made about 8 cuts, but the blade looked fine when I was done - didn't break a sweat.

Using a 10" Boss Hog blade to cut concrete retaining wall blocks. I installed it on my sliding compound miter saw and added a cheap electronic speed control from eBay just to slow it down a bit. The surfaces of the cuts are as smooth as glass. Only made a half dozen or so cuts so far so I can't comment on longevity but so far I'm impressed.

Extended a porch with bricks and pavers. Went through 4 others blades who claimed to cut masonry. No luck. This blade made all cuts fast and smooth. Blade still looks like new.

Wet or dry cutting was a breeze. Cut block and a 2 in slab of concrete. Wet cutting saved the blade. Will recommend it in the future

I am impressed at how well it cuts flagstone. I'm using it in a cordless grinder which runs a little slower than a corded grinder. The slower speed generates less heat in the blade for longer life. So far, it has dry cut over 20 linear feet of 2 inch thick flagstone and still looks sharp as new. Cutting 3/8" deep in multiple passes is quicker than trying to muscle through in deeper cuts. Used it to make flagstone steps for my front door, looks great.

I was skeptical. I had an Evolution blade (smooth rim) and a few others where the rim was smooth or serrated and were rated for wet or dry. The Boss Hog outperformed all my other blades in a dry application. Cuts much faster. I am using it for cutting up granite rocks and this thing is eating these rocks. Because of the design it will make a thicker cut, but I don't mind as my chisel fits better. I typically cut one or two sides about 2 inch deep and use a rock chisel and hammer to crack and split the rock. Using this blade, I have doubled my output.

I use the blade for cutting limestone into precise-dimension blocks. It cuts smoothly with little effort. I've cut over 100 so far with no problems whatsoever. The blade shows no sign of wear.
