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

Works Great For 18Ga Patch Panels
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.

Just good enough to finish the job
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

Nice heavy built
This tool is great! Punches holes and bends the lip of sheet metal with smooth ease. Glad I added it to my metal working tools.
