The AMERICAN SAW MFG CO 1991559 is a 3-pack of T-shank jig saw blades engineered for cutting thick metal stock. Each blade measures 3-5/8 inches long by 3/8 inches wide by 0.037 inches thick and carries a 14-tooth-per-inch configuration. The T-shank mount provides a secure, tool-free connection to most modern jig saw chucks. Power Blast Technology enhances blade durability under sustained cutting loads, while the patented T2 Technology delivers fast, efficient cutting across a range of metal applications. These blades are suited for trade professionals who need reliable performance cutting ferrous and non-ferrous metals.
These blades are designed for metal cutting applications where material thickness exceeds 3/32 inches. Typical use cases include cutting steel conduit, sheet metal panels, metal framing components, and similar structural metals encountered in HVAC, plumbing, electrical, and general mechanical work. The 14-tooth pitch provides the controlled, clean cut required for thicker metal stock. Each pack contains 3 blades, making it practical for extended job-site use without frequent restocking.
Designed as a T-shank jig saw blade replacement compatible with jig saws that accept the standard T-shank interface, which covers the majority of current-production jig saw models across major tool brands.
T-shank blades are installed and removed without tools on compatible jig saws — confirm the saw is unplugged or the battery pack is removed before changing blades. Wear appropriate PPE including eye protection and cut-resistant gloves when handling and cutting metal. Follow the tool manufacturer guidelines for blade speed settings when cutting thick metal stock.
