Lenox 21881ST714040CT Circular Saw Blade, 7-1/4 in Dia, 5/8 in Arbor, 40-Teeth, Titanium Carbide Cutting Edge

I am not easily impressed but was amazed at the performance of this blade. I cut 3/8" thick plate steel with my circular saw as if it were plywood.

I am currently making pipe fittings, for a geodesic dome. I am using 1" EMT steel conduit, for the fittings. I used an abrasive blade, to cut each 5" piece. Every piece i cut, I had to go over, with a grinder. I was apprehemsive about putting a Lenox 7-1/4" blade, on my Ryobi Miter saw. But, after checking the max RPMs of my saw, to the specifications for this blade, I went ahead and installed it. My first cut, let off 5 or 6 sparks, but, then cut the steel like butter! The same was true, on my 100th cut. The cut is cleanand burr free. AND, takes a fraction of the time, compared to an abrasive blade. I am sold! This blade, blew me away! It now compliments my new, Ryobi Steel cutting Compound Miter Saw very nicely! Thank you!
