CenterFire Insulation Knife Blade 29961

Made of durable carbon steel, this CenterFire Insulation Knife Blade features a non-serrated edge that quickly cuts through foam and fiber insulation products while eliminating dust and debris. It easily cuts notches and squares around outlets, and it has just the right amount of flex to efficiently cut expanded foam around windows or circles in sheets. Choose between a 3", 4” or 7” blade to suit your preference. Both options fit standard utility knife handles and a Sawzall-type reciprocating saw. Order a single blade or stock up with a 3-pack. Our dust-free Insulation Knife Blades are Made in the USA with Global Materials.
