I have two different sized chassis punches for sale. These are extremely handy for anyone doing sheet metal work or work with electronics component boxes where nice, neat round holes are required. These are high quality and vintage, in perfect condition. I believe that they are made by Greenlee. Asking $25 for the pair or make a reasonable offer. They are around $30 each plus shipping on Ebay. If interested, please contact me for more info. Thanks!
