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. Designed for use with the M18 FUEL™ cordless 5-3/8 in. to 5-7/8 Ft. metal saw, these blades feature a thin Kerf that reduces the amount of drag and resistance while cutting, resulting in more cuts per charge. Features: Eliminates the need for lubricants, saving time and money; Reduces heat build-up in cut material, leaving material cool to the touch and able to be handled right away; Eliminates burrs, leaving safer to handle material and no need to clean up after cut; Faster cuts, better precision, and better cuts per charge
