The Milwaukee Thick Kerf Framing Circular Saw Blades offer the straightest cuts and longer life in wood. These blades are designed with a High Performance Thick Kerf, allowing you to get the straightest rip cuts and ultimate stability in softwoods, hardwoods, lumber, and laminated beams. The diamond venting pattern allows for cool cutting and improved chip ejection while the cobalt-infused carbide teeth stay sharper longer. The Milwaukee 10-1/4 in. 28T Thick Kerf Framing Blades have a 5/8 in. arbor hole with a diamond knock-out for use with 10-1/4 in. Circular Saws.
