Product Description
The IRWIN 25834847 is a 3-1/4 inch, 20 TPI U-shank jig saw blade built for cutting metal. Manufactured from high-speed steel, the blade delivers sharp cutting edges and extended durability under repeated use. At 20 teeth per inch, it is suited for controlled cuts in ferrous and non-ferrous metals, aluminum, and sheet metal. This pack includes 2 blades, making it a practical choice for tradespeople who need a reliable backup on the job. Licensed electricians, plumbers, HVAC technicians, and general contractors frequently reach for this blade type when working with metal conduit, brackets, sheet stock, and similar materials.
This blade is designed for use in U-shank compatible jig saws. Its 20 TPI geometry is appropriate for thin to medium gauge metal where a finer tooth count helps reduce burring and maintain cut quality. It handles ferrous metals such as mild steel, non-ferrous metals such as copper and brass, aluminum sheet, and sheet metal fabrication stock. The U-shank mount style is a universal fit standard found on a wide range of corded and cordless jig saws designed to accept that shank type.

Installation Notes
Blade changes should be performed with the saw unplugged or battery removed and the blade fully cooled before handling. Follow the saw manufacturer's blade-change procedure for U-shank models.
