If you do a lot of work with round sheet metal ducting, this is well worth the investment; in one job, I used it so many times that I didn't think I'd need it, and it saved me so much time; it's far faster and produces a more professional look than a hand crimper. It takes some getting used to, but once you do, it's fantastic! - Henry G.

📋Frequently Asked Questions:

Q: How to use the crimper attachment?
A: Begin the crimp to one side of the pipe or duct seam by gently pulling on the driver trigger and angling the CRIMPER onto the metal edge. Controlled movement of the crimper around the pipe's circumference is required. Finally, as the crimper approaches the other side of the seam, angle it away from the metal.

Q: Can I use my standard drill instead?
A: No, it has to be an impact driver. It’s 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.
