I don't now the name for these in english... google translated it in "reamers". they look usable to me.
The english term is "reamers" What does the paper say? can't read it because of the reflections, etc.
They are indeed reamers and are used to very minutely enlarge a drilled hole to a more precision size. If still sharp, they certainly be re-used. Always use lubricant and always turn in the same direction, both going ito and out of the piece being reamed. Although I've seen them used under power, I've always used them using a tap chuck, by hand.
what are those sizes? i may know someone who can use some like that, you need some good size machines to use some of those

Im on a tiny laptop ... are those input pilot shafts? ... they look to darn big to be reamers or taps
They are Reamers and they look good. Just don't ever turn them backwards, away from the way they cut. Do it one time and you will have overpriced gear shift handles.
...They are Reamers.....hard to tell the shape they are in with pictures...with the complete set with the wooden handle I've seen them go at auctions from $10 dollars to $50 dollars....most of the ones I've seen have 12 bits in a wooden box....
They are reamers and you need a Bridgeport machine to use them properly. Judging from the picture they look to be in very good condition which will help with the price, but your buyers are limited to those who have the correct size machines. Unless you know of someone who has a machine shop, Ebay them with a starting bid of $40 and see where it goes as bidders are from all over the world.
sounds like it's a special reamer set for the busings in some old transmission. Neat, but probably not real useful.
if you decide to sell them at some point I might be interested, i'm not sure of the exact measurements, but I collect and use reamers and machining tools, They might be a size I could use one day or something I use anyway
