The MILWAUKEE 48-42-5240 is a T-shank jig saw blade engineered for wood cutting applications. Built from high carbon steel, this blade delivers consistent performance across rough cuts and general woodworking tasks. At 4 inches in length with a 10 TPI tooth configuration, it is suited for moderate-thickness lumber and sheet goods where a clean, controlled cut is required. Sold in a 5-pack, the 48-42-5240 is a practical stocking choice for carpenters, finish contractors, and trade professionals who run jig saws regularly and need reliable blade supply on the job.
This blade is designed for use with T-shank compatible jig saws, which represent the current industry-standard shank format across most major tool platforms. Typical applications include cutting dimensional lumber, plywood, OSB, and similar wood-based materials in residential and light commercial construction environments. The 10 TPI tooth count balances cut speed with surface finish, making it appropriate for general framing and trim work where precision is needed without sacrificing throughput.
Designed for use with T-shank compatible jig saws for wood cutting applications.
Blade installation and changes should be performed with the tool unplugged or the battery removed. T-shank blades seat into the blade clamp mechanism without tools on compatible saws — confirm the blade is fully seated and the clamp is locked before operating. Inspect the blade for cracks or missing teeth before each use and replace if damaged.
