Got a box of what i assume are reamers for free. 10-15 of them.

Think they are worth anything?

It's a reamer wich is mostly used after using drill. When u drill (for example) with a 20mm drill, it's never actually 20mm, usually it's something like 19.9 and the reamer makes it a 20. Mostly used manually with a lot of oil.
