Diablo 7

One of the best new accessories we saw at STAFDA 2018 is the Diablo 7-1/4″ Cermet blade. Cermet is a contraction born from ceramic and metal to create a multi-material tooth that’s capable of cutting through metal – including stainless steel.

The 7-1/4″ size isn’t the first in the line. We reviewed one of the original 14″ Cermet blades a while back and its performance is impressive, to say the least.

One of the limitations on the larger blade is that it’s designed for cold cut chop saws running 1800 RPM or less. Who makes a 7-1/4″ saw with that low an RPM?

What makes the Diablo 7-1/4″ Cermet blade so attractive is that it’s able to run up to 5800 RPM. In other words, your standard wood-cutting circular saw is now a metal cutting saw, even if it’s cordless.

Think about the implications of that for a second. Diablo just gave you a $30 option to avoid having to purchase a second saw specifically designed for metal cutting.

That’s great if it can do the job. In a demonstration, the 7-1/4″ blade made 50 cuts in stainless steel pipe and still had life left in the blade. In fact, Diablo tells us that they are getting up to 100 cuts in their internal testing. The saw they used was the Makita 5007 that you can pick up for a little over $100.
