Lenox 1991408 Bi-metal Jigsaw Blade 6 Tpi U-shank 25 Pack

Product Description

The LENOX 1991408 is a bi-metal jigsaw blade designed for general-purpose cutting applications. It runs a U-shank configuration and delivers 6 teeth per inch (TPI) with a ground tooth set, making it well suited for slower, aggressive cuts through wood and similar materials. The blade measures 4 inches in length, 0.375 inches wide, and 0.05 inches thick. Bi-metal construction bonds a high-speed steel tooth edge to a flexible alloy steel body, improving durability and resistance to breakage under lateral stress. Sold in a pack of 25, this blade is a practical stock item for shops and service vehicles. Carpenters, remodelers, and general tradespeople will find this a reliable consumable for repetitive work.

This blade fits U-shank jigsaw models and is appropriate for residential and light commercial cutting tasks. At 6 TPI, it is optimized for faster, rougher cuts in wood, particleboard, and similar soft materials rather than fine finish cuts. The 4-inch blade length provides adequate depth for framing lumber, rough carpentry, and demolition work where cut quality is secondary to cut speed. It is not designed for contour or curved cutting applications.

Installation Notes

Jigsaw blade changes should be performed with the tool unplugged or the battery removed. Insert the U-shank fully into the blade clamp until it seats and locks securely before operating. Inspect the blade for cracks or missing teeth before each use and replace immediately if damage is found. Blade changes do not require special tools beyond what is built into the jigsaw clamp mechanism.
