4-1/2-Inch Premium Tuck Point Diamond Blade for Mortar, Concrete, Brick - Arbor 5/8"-7/8" - Laser Welded

It cut concrete like a hot knife to butter. And also used it to cut granite stone it takes more time but it works fine after three to four hours of cutting the blade seems to ware a little. So I think it would last a long time for cutting concrete alone. Update after 3 years. So three years later I used this old blade again this time one new and old concrete. It cut concrete extremely fast no matter what kind of concrete. Concrete rated for 5000 psi and after cured for about six months. It cut like nothing. It is insane blade. It’s really an amazing quality piece.

Worked well cutting out old mortar

Little to be said beyond my headline. This quickly cut out out old mortar for re pointing a large brick planter. Definitely a dusty job but can't imagine doing it any other way

My son-in-law does masonry work and needed the blade for a job he was doing. He said it did the job.

I bought it to do some brick pointing but am waiting for warm weather.

should probably have a fan to blow away the dust while you're cutting because it gets thick. The blade does what I wanted it to. They shipped really fast and the price was great too.
