The Arrow Titanium-Coated Flush-Cut Blade is ideal for cutting wood containing nails – as well as metal, PVC, drywall, and more – with your oscillating tool. The large 3 1/2" bi-metal blade with titanium-nitride coating along the tooth strip prolongs blade life by reducing heat and increasing hardness. The unique blade shape allows users to perform flush cuts in a variety of applications. And best of all, the Titanium-Coated Flush-Cut blades come with a universal-fit open-back connector for use on most major brands of oscillating tools.
