Lenox 1991573 Bi-metal Jigsaw Blade 24 Tpi T-shank 25-pack

Product Description

The LENOX 1991573 is a bi-metal jigsaw blade designed for cutting applications that demand durability and consistent tooth geometry. Measuring 3-5/8 inches in length and 3/8 inches in width, this blade features a ground tooth set at 24 teeth per inch (TPI), which produces clean, fine cuts in sheet metal, thin-gauge materials, and similar workpieces. The 0.037-inch blade thickness provides a balance of rigidity and flex suitable for controlled jigsaw work. Sold in a 25-blade pack, the 1991573 is a shop-supply choice for tradespeople who run through blades regularly and need a reliable stock of compatible replacements on hand.

This blade is suited for use in trade and light industrial settings where repetitive cutting of metal, plastics, or composite materials is required. The T-Shank design offers tool-free blade changes on most modern jigsaws that accept the universal T-Shank interface. HVAC technicians, plumbers, electricians, and sheet metal workers commonly keep bi-metal jigsaw blades in their kit for cutting ductwork, conduit knock-outs, PVC, and similar materials in tight or awkward spaces.

Key Features

• Bi-metal construction for extended blade life compared to high-carbon alternatives
• 24 TPI ground tooth set for fine, controlled cuts in metal and thin materials
• T-Shank interface compatible with most modern jigsaws accepting universal T-Shank blades
• 3-5/8 inch blade length with 0.037-inch thickness for rigidity during straight and curved cuts
• Contour cutting not rated for this blade — intended for straight and shallow curved work
• 25-blade pack reduces restocking frequency for high-use shops and service fleets

Compatibility

Designed for use in jigsaws that accept the universal T-Shank blade interface, which is the standard fitment on the majority of current-production jigsaw models across major tool brands.

Installation Notes

Blade installation and removal should always be performed with the tool powered off and the battery pack removed or the power cord unplugged. T-Shank blades seat into the blade clamp without tools on most compatible jigsaws — confirm the blade is fully seated and the clamp is locked before operating. Inspect each blade before use and discard any blade showing cracks, missing teeth, or deformation. Wear appropriate eye protection and gloves when handling or changing blades.
