roysboystoys Posted July 23, 2017 Share Posted July 23, 2017 (edited) Thought I'd share this oddball tool I picked up. I thought at first it was gasket cutter or glass cutter Here is the Patent link info: 1341067 https://www.google.com/patents/US1341067 Made by Standard thermometer Co. It's a hole cutter for dash boards , never would have guessed. Edited July 23, 2017 by roysboystoys (see edit history) Link to comment Share on other sites More sharing options...
Guest Posted July 23, 2017 Share Posted July 23, 2017 Neat tool. Nice to see different ways it was done. I have a complete set of punches from 1/2" to 4" like these. http://www.aircraftspruce.com/catalog/inpages/ats123chole.php Link to comment Share on other sites More sharing options...
Bhigdog Posted July 23, 2017 Share Posted July 23, 2017 Hole "punch" for flat sheet metal maybe. Convex or concave metal? Not so much............Bob Link to comment Share on other sites More sharing options...
