Stop in for a cup of coffee

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.
Even the best blades will fail miserably if not right for what your cutting. Wrong TPI and you will just heat it up... your done. Just like drilling. Will work harden the metal and the blade dulls even more. Keep at it and watch the paint burn as it starts to glow. LOL
