Diablo's 4-1/2 in. Cordless Framing blade is ideal for general construction applications, including fast, efficient ripping and crosscutting. Diablo's blade cuts rough framing lumber, high quality finish lumber, plywood, OSB and hardboard siding with the smoothest, fastest and most accurate cut. The thin kerf design requires less cutting power from the user and the saw for better control over the cut. Diablo's unique design, extra-tough steel plate and proprietary carbide tips deliver longer life - and frames more houses - than other framing blades.
