MILWAUKEE? Metal Circular Saw Blades were specifically designed to exceed the expectations of contractors for blade life, cut quality, and speed in the most demanding metal cutting applications ? without a lubricant. A hand-tensioned, hardened alloy steel body extends blade life and delivers the highest quality cuts available. Carbide Tipped teeth with Alternate Top Bevel grind shear through metal leaving burr-free, cool-to-touch cuts.
