Delta Diamond Cougar HD 14 Inch Diamond Saw Blade, Supreme Grade, for Reinforced Concrete, Masonry, Stone, Laser-Welded, Segmented-Turbo, .125 Width X 1"-20mm Arbor (14")

i returned the blade for refund, however it lasted the longest out of 6 different blades. the first 2 weeks, it cut very well, then the last week it was dull, and i was forcing the cut. i am cutting a rock called oklahoma silver mist, 1 to 2 inches thick, dry. i am only able to cut about 2 to 4 rocks per day. usage is about 4 hours. it did perform bgetter than bosch, rigid, evolution, and the cougar hs.

We run a rental store and rent these blades to customers. They seem to last as long as some of the other more expensive blades. We have purchased quite a few of them now and will continue to do so.

The best saw blade I've buy yet.But there customer service is far above any other supplier I've used.I would definitely recommend them.

This blade is aggressive! I was using a hf blade before this one. This blade cuts twice as fast as my old blade. So far it hasnt dulled cutting my pool. Slices right through rebar. Made my job much easier.

This blade cut thru concrete like it was soft butter. I'm impressed. can't speak to longevity as only used it for about 1 hour so far but really cuts fast.Yes, I would buy it again, and recommend it to others. Pay a little more, get a lot more, for your money

Cuts hard concrete like butter. Seems like it will last.

Great blade for the price! Cuts well thru cured concrete. Recommend using water with it.

This blade cuts extremely well . It cuts super fast . A curb cut was taking 15 minutes now takes 4 or 5 minutes . Time is money , this blade saves me time and makes me money !
