Cutting HVAC ductwork poses unique blade challenges. Rectangular ductwork sections require cuts started from the middle of a sheet metal face, without the edge access that standard reciprocating cuts rely on. Flexible duct systems combine mylar or wire-reinforced outer layers with insulation batting and inner liner layers, each needing 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 call for specific tooth geometry to cut cleanly without tearing and deforming the metal at the cut edge.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpecialty duct blade for sheet metal ductwork and mixed HVAC duct materials\u003c\/li\u003e\n\u003cli\u003ePurpose-designed for the M12 HACKZALL stroke and motor, optimized for the compact saw\u003c\/li\u003e\n\u003cli\u003eOne-handed HACKZALL is ideal for duct work that needs a free hand to support material\u003c\/li\u003e\n\u003cli\u003e5-pack for HVAC contractors with a regular duct cutting and modification workload\u003c\/li\u003e\n\u003cli\u003eCompatible only with the Milwaukee M12 HACKZALL reciprocating saw\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Milwaukee","offers":[{"title":"Default Title","offer_id":52315303969058,"sku":"MWKE-49-00-5424","price":9.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1001\/1302\/3266\/files\/af08f95fd03d9e98d22f4a193800a6e52d5f627c.jpg?v=1792795206","url":"https:\/\/whiskeyranchtools.com\/products\/milwaukee-49-00-5424-m12-hackzall-blade-duct-5ct","provider":"Whiskey Ranch Tools LLC","version":"1.0","type":"link"}
