I got below Wesson quick change tool holder thing with a job lot of reamers. It's a really cool system, the tool sits in the holder very solidly, yet releases with no effort. The holder has an MT2 shank and is stamped "WESSON BMH21"; the 1" tool is stamped "WESSON 14/16" and "PAT. 2059496" (the stamping looks like it's done by hand, stamping is clearly not their forte). I unfortunately don't have any other tools for it (nor do I have a use for it anyway...). I wonder what these are used for? Something CNC? I did a patent search, but nothing came up. When I google "Wesson" I get mostly gun related search results. I did find a cutting tool manufacturer called VR/Wesson, but they don't have anything like this listed on their website. Can anyone tell me what this is?
