11870 Circular Saw Blade, 10 In., 180-tooth, 5/8 In. Arbor

The Irwin 11870 is a 10-inch circular saw blade with 180 teeth, engineered to deliver smooth, precise cuts in delicate sheet goods and composite materials. Fitted with a 5/8-inch arbor, it works with most standard 10-inch circular saws. The high tooth count and precision-ground design minimize tear-out and splintering, making it ideal for plywood, veneer, OSB, and plastic applications where a clean finish matters.

Whether you're cutting cabinet components, installing trim, or working with thin-gauge materials, this blade produces the fine edge quality that professional carpenters and serious DIYers demand. Its fully hardened steel plate runs truer and longer while maintaining sharpness through extended use, delivering the accuracy and smooth finish that woodworkers expect.
