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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBi-metal construction for extended blade life compared to high-carbon alternatives\u003c\/li\u003e\n\u003cli\u003e24 TPI ground tooth set for fine, controlled cuts in metal and thin materials\u003c\/li\u003e\n\u003cli\u003eT-Shank interface compatible with most modern jigsaws accepting universal T-Shank blades\u003c\/li\u003e\n\u003cli\u003e3-5\/8 inch blade length with 0.037-inch thickness for rigidity during straight and curved cuts\u003c\/li\u003e\n\u003cli\u003eContour cutting not rated for this blade — intended for straight and shallow curved work\u003c\/li\u003e\n\u003cli\u003e25-blade pack reduces restocking frequency for high-use shops and service fleets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned 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.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eBlade 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Bi-Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Width\u003c\/strong\u003e: 3\/8 inches (0.3750 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Thickness\u003c\/strong\u003e: 0.037 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTooth Set\u003c\/strong\u003e: Ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Toothed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: T-Shank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContour Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25 blades\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112802\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LENOX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1991573\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LENOX","offers":[{"title":"Default Title","offer_id":51541111832882,"sku":"1991573","price":72.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/932eb676a59510e66f1c4609b409dab0.jpg?v=1785868582","url":"https:\/\/voomisupply.com\/products\/lenox-1991573-bi-metal-jigsaw-blade-24-tpi-t-shank-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
