Based on actual field trials, the TurboCrimper Impact is 78% faster than using a manual sheet metal crimping tool!

This sheet metal crimping attachment is designed to work with a minimum 12 volt DC cordless or maximum 7 amp AC corded IMPACT DRIVER. No set up or adjustment is needed. Immediately begin crimping multiple sizes, types, and thicknesses of round metal duct (Including spiral duct and metal stove pipe). It’s also easy to balance while using and stores comfortably in a pouch or bag when not in use.
