Set Mac Tools Cobalt Drill Bits No. 6338DS Incomplete Set
Appears that the following are missing: 3/8, 23/61, 19/? 11/64, 9/64, 7/64, 1/16. There are a few extras in the bottom. I’m not knowledgeable enough about the set to determine what size they are but included pictures. If you’d like more pics, just ask.
