Product Description
Milwaukee M12 HACKZALL Duct Blade — 5 Pack
Model Number: 49-00-5424
The Milwaukee 49-00-5424 is a 5-pack of M12 HACKZALL Duct Blades — specialty blades for the Milwaukee M12 HACKZALL compact reciprocating saw specifically engineered for cutting HVAC sheet metal ductwork, duct board, flex duct, and the mixed metal and insulation materials in duct system installation, modification, and service work. HVAC ductwork cutting presents unique blade challenges — rectangular ductwork sections require starting cuts from the middle of a sheet metal face without the edge access that standard reciprocating cuts use, flexible duct systems combine mylar or wire-reinforced outer layers with insulation batting and inner liner layers that each require different blade action for clean cuts, and the thin-gauge galvanized steel of rectangular duct bends and flexes away from standard blades in ways that require specific tooth geometry to cut cleanly without tearing and deforming the metal at the cut edge.
Milwaukee specifically designs M12 HACKZALL duct blades for the compact saw's stroke length and motor characteristics to maximize performance in HVAC duct cutting applications — standard full-size Sawzall blades used with adapters perform differently in the M12 HACKZALL's shorter stroke geometry. The M12 HACKZALL's one-handed compact design is particularly suited to HVAC duct work where the technician must often hold or support the duct section with one hand while cutting with the other in confined mechanical room and ceiling plenum spaces. The 5-pack provides multi-blade supply for HVAC contractors and sheet metal workers who use duct blades regularly across multiple duct installation and modification projects where sustained use depletes single-blade supplies quickly.
