The Malco TurboCrimper® IMPACT turns your impact driver into a high-speed sheet metal crimping tool. Based on field trials, it works up to 5 times faster than a manual hand crimper, helping HVAC and sheet metal contractors save time and labor on every duct connection. Designed for use with a minimum 12V DC cordless impact driver or maximum 7-amp AC corded impact driver equipped with a quick-release 1/4″ hex chuck, this attachment requires no setup or adjustment. Simply chuck it up and begin crimping. The TurboCrimper IMPACT quickly forms uniform crimps in 30–24 gauge galvanized steel round duct, spiral duct, and cold rolled steel stove pipe. Its compact design is easy to control around the pipe circumference and stores easily in a pouch or tool bag when the job is done. No cords to manage. No hand fatigue from manual crimpers.
