Stop in for a cup of coffee

I mostly buy those and Milwaukee
Maybe I’m not buying the right Milwaukee line of blades, but I’ve had terrible luck with them. Usually only last one cutting before the teeth are worn down. Took 3 of them to cut one quarter off the car. These diablo blades cost 3 times that of the Milwaukee’s, but a single blade as cut the entire floor of the dart and the cross member and some 3/4 square tube without any signs of wearing down.
