Astro Pneumatic Tool605PT ONYX Pistol Grip Punch/ Flange Tool with 5.5mm Punch

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.

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.

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

Great product very heavy duty, highly recommended.

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

Makes a nice, even butt flange for thin sheet metal. Very easy to weld and have smooth joint.

Clamp and anvil alignment is poor and ends up leaving a dimple on the flange side a big scuff on the other when used on 0.040 aluminum. 0.032 galv. steel didn't show scuff but still had a pretty visible dimple at the corner of each hit. Works great if you aren't worried about looks but would be unacceptable for a professional ductwork job where the flange is visible. Punch works great. Mine had very fine aluminum swarf in both the pneumatic housing (24 and 25 on parts diagram) and hydraulic section (12 and 19 on parts diagram). Oil was glossy gray looking at the fill plug before first use. Drained oil, completely disassembled, gave a few squirts of carb cleaner, lightly oiled, reassembled, and refilled tool in about 20 mins. Oil at fill plug didn't show any gray particles after about 2 hours of hard use (8 hr shift) so it must have been dirty from the factory and not from wear in. Quiet, comfortable, powerful, and solid feeling. Would be 5 out of 5 if it weren't for the misaligned jaws
