NYTiger 3 Pack 4-1/2 inch Diamond Saw Blades 4.5" Angle Grinder Disc Wet Dry Segmented Cutting Wheel with 4/5-5/8 inch Arbor for Concrete Stone Brick Block Masonry

Used one of these three blades to cut pavestones for a circle of pavestones around a flagpole. It worked great, stayed sharp and I had no problems at all with it. This is a great value for the money. I cut about 25 bricks so the path leading into the circle fit and a few more for the outer edges. I even used the blade to put a small chamfer on the edges of the bricks so they had smooth edges. The blade did great at shaping as well as cutting. It was a great buy and performed just as well as the much more expensive blades I bought at the store for previous similar projects!

I am replacing the wood siding on the side of my house with cement fiber boards. I have tried everything to cut this stuff. It will dull a blade in just minutes. I have purchased blades for my circular saw made for cutting the cement fiber boards and they didn't hold up much better than regular framing blades. I saw these blades and figured I'd take a chance and glad I did. I have replaced an entire wall on my house and made each cut with 1 blade. I had to learn how to hold my grinder steady but other than that these blades cut through the cement fiber boards like crazy.

These blades work great for cutting concrete. I would have given 5 stars but the center hole was metric and not the standard size for my dewalt angle grinder. I was able to use a step bit to drill the center hole a tad bigger to fit. Works great. Just inconvenient.

These are awesome. These cut better than the high priced ones at the big box stores. I had to cut open a concrete wall to allow for a drain line. The blade cut through the concrete with ease and you can’t even tell I had used the blade. There was rebar in the wall which the blade didn’t like too much but it still cut it. The blade is definitely not made for cutting rebar but it does an awesome job on concrete. Definitely going to purchase again if needed.

Just got these blades and had to cut through a 2 inch thick concrete paver to fit it on my patio and it went through it with ease. I then had to trim a few bricks to fit our patio border area and again the blade sliced right into it with no problem. I did all these cuts dry with no water, lots of dust but easier to clean up for me. Great blades at a great price!

FYI, I did have to drill out the center holes to fit them on my tool… I guess I didn’t buy the right size? But they were less than a 1/16 too small… anyway, once I got this blade attached it cut like a dream. It was the easiest part of the job and I thought it would be the hardest.

I made the mistake of buying several of these at once. Amazon makes returns a pain in the ass! These blades don't fit any size grinders available in America. So I did what other people on here did and drilled out the hole to the right size. Theres two hours of my life I will never get back

Over all they work great. Wish they lasted longer but concrete will take its toll.
