Put this blade on your 12" miter saw and you'll never want to take it off. Fortunately, you won't have to take it off very often, since our micrograin carbide teeth hold an edge for a remarkably long time, and our thin kerf design keeps heat build-up and the resulting tooth damage to an absolute minimum. With 45 carefully engineering teeth in a flat raker / alternate top bevel pattern, the General Purpose Miter Blade does a great job on molding, lumber, and most any other material you can put on the saw table. And when the time finally comes to resharpen the tool, you'll enjoy having CMT's unique, illustrated resharpening instructions handy to give to your saw service. Like the entire ITK line, the General Purpose Miter blade features Anti-Kickback Design, Tri-Metal Brazing, Laser Cut Arbors, and carefully engineered Expansion Slots and Sound Dampening Channels.
