The 4-1/2-inch x 7/8-inch 30 teeth metal cutting saw blade produces fast, accurate cuts in a wide-range of mild steels. These blades feature Hi-Density Carbide engineered exclusively to deliver maximum performance, superior quality cuts and longer life when compared to standard grinding discs. Designed with a Triple Chip Grind (TCG) and Perma-SHIELD coating, these blades slice through the toughest of metals to produce precise, burr-free cuts with less sparks. A controlled cutting action produces larger chip sizes that generates less dust and airborne contaminates. The thin kerf body minimizes material removal and requires less cutting power, delivering fast, clean cuts in cordless and corded trim saws.
