We have a set of vintage things that look like drill bits but the ends are star shaped. The smallest is 1/8" and the largest is 1-3/4". There is no brand name and the sizes are etched by hand. I've looked at spiral reamers, transmission reamers, and searched the Web for as many key words as I can think of and I can't figure out what these are. As a bonus, an approximate value would be great, too. We'd like to sell them but can't accurately describe or evaluate them. Thank you for any information you might be able to giveme!
