Applications

Engineered for automotive technicians and mechanics, this Milwaukee heated workskin is ideal for unheated or partially heated garages, service bays, and outdoor lots for cold-weather diagnostics, undercar repairs, tire service, and mobile service calls. It is equally suited for technicians in fleet maintenance yards, industrial facilities, warehouses, and cold storage operations where ambient temperatures remain low.
