Excellent Performance
recently upgraded to the IRWIN MARATHON Carbide Cordless Circular Saw Blade, and it's been a game-changer for my woodworking projects. The ultra-thin kerf design truly delivers more cuts per charge, enhancing the efficiency of my cordless saw. The face-ground, construction-grade carbide teeth provide fast, clean cuts, and I've noticed significantly less tear-out compared to other blades I've used.One aspect that stands out is the blade's durability. Even after cutting through reclaimed barn wood and occasionally hitting hidden nails, the blade remains sharp and shows no signs of wobble . Additionally, the aggressive hook angle facilitates faster cuts, making my work smoother and more precise.Overall, the IRWIN MARATHON blade offers exceptional value. It's a reliable choice for anyone seeking quality and performance in a circular saw blade.

As expected!
Not the best blade out there and not the worst but I consider it right in the middle “quality” wise and awesome price. Just needed it for my little ryobi circular saw and it’s the job well. Could you run a Diablo and maybe get some better cuts? Sure but not worth the 3x the price tag either.

Sharp blade essential for battery powered saws
Should have replaced my original blade years ago on my Craftsman 19.2v circ saw. .I thought the batteries were dying.. Nope, it was a dull blade.This new Irwin is thinner and the saw rips thru pine quickly, and doesn't overwork the batteries.it's a bit of a rough cut, but i have plenty of files and sandpaper.
