I needed one of those for a young lady named Melba I knew back in the 90s... Shawty looked like she had Don King in a leglock!
Jesus, now @Gorilla George is going to buy up all the .22LR and extruded aluminum trying to fuck things up even more!
It's an extrusion that was being milled, but somebody forgot to turn the coolant on..... I have an endmill that looks like that too. . I used to have it on my desk as a reminder to always keep the coolant tank topped off.
