12/14/2023 0 Comments Benchmark abrasives locationI was tempted to order a Oshlun blade instead after PF's testing but decided to go with the original choice from Benchmark just to see if their TCT blades are worth a damn since I'd be saving 10$ as well. RPM does play a big role in tooth durability I believe, I've had occasions where my saw has been anything but smooth, and it's seen everything from aluminum to stainless flat bar, I've used it to cut a 2" piece of 1/4" thick AR400, and I've also made a half dozen cuts through 5/8" thick and 6-1/2" wide I beam sides. It runs at 3500RPM rather than the more typical 5800 RPM of a standard circ saw. My saw is what appears to be an old discontinued northern tool equivalent to an evolution circular saw. The only tricky part about using these circular saws is you can't let either piece (the left side and/or the right side) capsize inward or it might stall the blade and cause chipped/broken teeth. It's kinda slow (and slows a bit when going through a cut, which is good too), and low-power, because the motor is small, but for times when I want to cut a couple pieces from my outdoor "scrap pile", it works out so I don't have to grab the 10ft long piece drag it all the way to the garage at the front of the house, just to get a small piece cut from it. ![]() I have a cheapie Harbor Freight Bauer cordless saw and put a Diablo 6½"Cermet metal blade on it because 1) I got it open-box for $20 and I already had the 5.0 Ah battery for it, and 2) the speed of the Bauer is perfect for it (4000 RPMs rated, probably measures out much lower, lol). Which blade do you run in your Evo saw? Project Farm did a 14" carbide blade comparison a few weeks ago. I've never used one or even seen one used for that matter. I've wondered if the hand held saws tend to grab and bite if you don't hang on well enough, or when cutting out of the part if it doesn't tend to pinch. I've got a 14"/15" Evo saw and I have no idea how they make these blades last the way they do. ![]() ![]() What RPM does that saw run at? Was it made specifically for metal cutting and runs at a slower speed like the chop saws do, or is it just a standard circular saw with a metal cutting blade in it? If you want to buy a blade to test out, I can't imagine anyone not wanting to hear a review on it.
