Delta Diamond Gator Blade Supreme 7 Inch Wavy Core Turbo Diamond Saw Blade, DM-7/8"-5/8" Arbor, for Masonry, Concrete, Stone, Granite, Wet/Dry, Continuous Rim (7")

Used it cut a 2 inch wide channel into a concrete block wall. It performed better than expected, I bought two just incase but didn't need the second one. Great value for the price.

This blade was used to cut in half almost 1000 sqf of floor tiles 2cm thick. It is very durable and stable.

It's one of the best quality that I've tried so far.

cuts clean and fast and lasts a long ass time

Very tough and durable.

Well maybe not butter but this made cutting my concrete floor to run electric wire through super easy. I did use water but the cut you see in my picture took all of about 20 minutes for both cuts. 10 each minutes for 70" long at 3/4" deep.Amazing cutter! Buy one!!!
