Existing blades are meant to be used on metal cutting chop saws that are ususally 1500 - 1800 rpm. These new blades can be used on regular circular saws doing 3000+ rpm.
The new blades are great. The bad thing about this demonstration is while he was using the abrasive cut-off wheel, he acted like a late night infomercial. He pushed just hard enough to generate sparks without really cutting the metal efficiently. Annoying. Diablo needs to let their products speak for themselves and stop the fabricated drama.
What was the thickness and age of that abrasive blade? No way it takes that long. Diablo makes some of the best blades I've ever used so I see no reason for the deception. Pretty annoying. Anyone using these products sees right through the BS. No need for it.
241 sec in, to cut 3mm x 6mm loaded cutting disc. go f..k me. How many out there have cut two inch square tubing. really it takes that long. yeah na na
