Astro Pneumatic Tool 605PT ONYX Pistol Grip Punch/ Flange Tool with 5.5mm Punch

I haven't tried the punch yet but the flange works really nicely.

Great product for the price used this to punch holes in all the sheet metal during a 64 impala restoration we are working on. Worked flawlessly.

Bought this for my Son, he told me that it a very nice tool. Works well, great tool. Highly recommend.

Tried several panel crimper and this one is a little more expensive but this one actually works for more than one job I am pleased each time that I use this tool

Its not a type of tool that everyone needs, but if you do, this one works well. Both functions do what they should.

An amazing tool for the price, I am starting up a small custom fabrication shop and have found this tool to be strong well built and very functional. It will punch out holes for 3/16" rivets quick and easy, it will also make flanges fast and perfect. Amazing results if you are tig welding 2 pieces of sheet metal together. You can pretty much weld it with out a filler or (autogenoursly) but with light use of filler metal a almost inzizable seam is achieved. Highly recommended! Don't by a local discount hardware stores unit. I tried prior to this the harbor and northern on. They were both straight units. The pistol version is much nicer to work with using 1 finger to operate vs more further it has the power to do the job right the first time and finally does not leak. This tool is just what you would expect from a snap on truck. I will be buying more air tools from this brand shortly. That says something.

Used this to make patch panel repairs on the 18 gauge sheet metal on my 68 Camaro. Comfortable to use. The head swivels/rotates. Worked great with my small CA Air Tools compressor and a 25ft long 3/8" air line. A sheet metal flange is so much stronger, easier to weld, and fitment-forgiving than butt welding. Highly recommend this tool.

It did its job on 18 gauge for me. If it lasts I will be satisfied.
