SLNIHAMS Snap Lock Punch Tool for Sheet Metal, 9”Gutter End Cap Crimper Tools for Vinyl and Aluminum Siding, End Cap Crimper, Vinyl Siding Tools for Sheet Metal Ccorner Notcherl

Works. Handy tool to have when replacing aluminum gutters. Well worth the money.

Easy to handle and use. Have no leaking where the end pieces were replaced. Would recommend and buy again should the need be.

Does the job nicely when joining gutter pieces

Excellent quality and a good grip. Would highly recommend.

Put my gutter up with easy. Made the job much easier. Sturdy, and easy to work. I took a couple of practices before hang all the gutters. It did take practice to get the pressure right, but was well worth to buy.

these work great on very thin aluminum. i got them because i've been doing prototyping with aluminum cans and it cuts through them like butter. I'd imagine these also work on something as thick as gutters. or if you just have some aluminum trim you want to edge a work bench in for impact resistance.

Much too lose tolerances. Won’t crimp well, no matter how hard the handles are squeezed together. They feel heavy duty and well made but unfortunately they don’t do a very good job at what they’re supposed to do. Wouldn’t recommend.

Great
