Delta Diamond Mad Dog HS 20 Inch Segmented Diamond Saw Blade, .140 X 1" Arbor, Made in USA, Premium, Wet/Dry, Laser-Welded, General Purpose Cutting Concrete, Masonry, Stone (20")

Using it to cut concrete it was very slow and made the job harder. The original blade that came with my saw was much faster cutting until it wore out. This one cuts almost as slow as my wire out blade. I'm pretty sure it's all related to how many diamonds are in the blade. The bad thing is I spent extra to get the premium blade but this thing is not premium at all.

We run 3 @ 9" grinders cutting stone and pavers so this isn't your casual user review. I don't mind paying more for a great cutting disc. This disc cut really well at first and didn't seem to wear down much. But after a while it became more work to get through the pavers. A 9" Makita blade on the same grinder beside it will cut better with less work until its worn all the way down. I actually removed this one only half used because it stopped cutting well. Just my 2 cents on the one I received.

I used this Blade to DRY cut 3" thick un-reinforced Landscape Block Cap. Worked perfectly. You have to in my opinion, go slow and let the saw do the work. The biggest problem is dust control. I rigged up a cutting booth to try and contain the dust as well as using the Shop-Vac attachment. I cut about 45 Cap pieces, so at this time I cannot judge the longevity, but so far so good. Will buy another when the time comes.

Price was good after an hour began to cut and provide a slower cutI ordered 2 and will return 1Overview for the money a good product however not suited for heavy duty

I was doing a tile job at home and needed to cut some stone type cove molding at 45 degrees for the corners. I have a wet saw but not a very good way to cut a piece that started at 10' long. So I purchased this for my chop saw and it did the trick. A little dusty is the only thing, but nice precise cuts.

What happened was the Blade was GREAT, But the saw I bought was just not up for the task. So I returned the saw and kept the blade in hopes of finding a good saw to work with this blade. Thanks.

It’s a great blade, I bought it to put on my new fourth stroke cutter and it works great

Needed something to cut bricks for our backyard paver project. Cuts them like butter.

Struggles to cut threw concrete and brickstoo expensive, at that price it should go threw masonry like butter
