Irwin 25821448 Circular Saw Blade 7-1/4 in 140T Steel

Product Description

The IRWIN 25821448 is a high-carbon steel circular saw blade designed for smooth, accurate cuts in wood and wood-composite materials. Built with precision-ground teeth and a fully hardened blade plate, it tracks truer and resists warping longer than standard blades. The heavy-gauge steel construction extends service life under repeated use. At 7-1/4 inches in diameter with a 140-tooth count and .087-inch kerf, this blade is suited for fine finish cuts where minimal tear-out and clean edge quality are priorities. It is installed and used by carpenters, finish framers, trim contractors, and skilled general tradespeople.

This blade fits standard 7-1/4 inch corded circular saws commonly used in residential and light commercial carpentry. The 140-tooth configuration makes it appropriate for finish work, trim installation, paneling, and sheet goods where a clean, splinter-free cut is required. The .087-inch kerf reduces material waste and demands less power from the saw motor, making it a practical choice for jobsite and shop use alike.
