Irwin IR11870 Circular Saw Blade 10 Inch 180 Tpi

Product Description

The IRWIN IR11870 is a 10-inch circular saw blade engineered for cutting non-metal materials. Built from tempered alloy steel, this blade delivers clean, controlled cuts in materials such as plastic, fiber, and composite sheet goods. The 180 TPI tooth count produces fine, smooth cuts with minimal tearout, making it well suited for finish-quality work where cut edge condition matters. The 5/8-inch bore fits standard 10-inch circular saw and table saw arbors common in trade and shop environments. Electricians, HVAC technicians, and general contractors reach for this blade when working with non-metallic conduit, PVC, and similar materials encountered during rough-in and finish work.

This blade is designed for stationary and portable circular saws used in residential and light commercial applications. It is a practical tool-bag addition for trades that regularly cut non-metallic materials on the job site, including electrical conduit, plastic pipe jacketing, and composite panels. The carded single-unit packaging makes it easy to stock and identify in a service vehicle or shop setting.
