This, all of it.i was lucky to find a real assortment of tool bits in a close out garage sale of an old machine shop. All vintage bits with all kinds of grinds for pennies on the dollar. It has turned into a real boon as some of the names are no more and absolutely beat my import bits hands down. What has been a real eye opener is this was personal stash and they are not grinds I was familiar with but was able to try them out. I have moved several to my assortment of quick change holders and have learned to copy and maintain those grinds. Most are 5/16 and 1/4 with a few 3/8 and that was probably why they were the last of the stuff but absolutely what I use on my 9x20 and Atlas7b. If they were still in a commercial shop they would be gone by now but in my shop I won’t need to ever buy bits again.
I have a couple pounds of old school tool bits. Mo-Max, Rex AAA, Three star, etc and other than the Mo-Max I have no idea what they are, but I take that if their marked there probably not just Hss but likely have some cobalt content.
