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™ cordless 5-3/8 in. metal saw, these blades feature a thin Kerf that reduces the amount of drag and resistance while cutting, resulting in more cuts per charge.
