Each blade runs 32 teeth per inch (TPI), optimizing them for fast, clean cuts through thin sheet metal, duct panels, and similar light-gauge materials. The bi-metal construction pairs a hardened cutting edge with a flexible body to resist breakage during aggressive cuts. A Perma-SHIELD non-stick coating reduces friction and prevents gumming when cutting metal, extending blade service life. HVAC technicians and sheet metal trades reach for this blade when working in tight spaces where a compact profile is essential.\u003c\/p\u003e\u003cp\u003eThese blades are designed for residential and commercial HVAC service and installation work, including ductwork fabrication, register openings, and thin-metal demolition. The fast puncture tip allows the blade to self-start in sheet metal without pre-drilling a pilot hole, reducing setup time on the job. The small gullet, high-tooth-count geometry limits vibration and chatter, which matters when cutting installed ductwork in occupied spaces. The 5-pack format suits contractors who run high blade volume on HVAC service calls or new installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e32 TPI bi-metal blade optimized for thin sheet metal and HVAC ductwork\u003c\/li\u003e\n\u003cli\u003eFast puncture tip enables direct plunge cuts without a pilot hole\u003c\/li\u003e\n\u003cli\u003eCompact 3-1\/4 inch blade body for access in tight HVAC cavities\u003c\/li\u003e\n\u003cli\u003ePerma-SHIELD non-stick coating reduces friction and prevents gumming\u003c\/li\u003e\n\u003cli\u003eUltra-hardened cutting edge for extended blade life in metal cutting\u003c\/li\u003e\n\u003cli\u003eSmall gullets minimize vibration and chatter during thin-metal cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a universal-shank reciprocating saw blade compatible with standard reciprocating saws accepting universal T-shank or similar bi-metal blade shanks.
