We have a key cutter that uses these special little 2.5mm end mills.
The key blanks are brass or some derivative there of.
They are F22’s
The shank is 6mm and the relief is 5.47mm ish.
They cut about 9-12 keys and must be replaced. They run about $35 each.
Any help?View attachment 302299
Are you breaking them or wearing them out? If you are braking them see if you can slow down the feed speed. If you are wearing them out you may have the HSS version. There is a solid carbide version available for around $50 each but may last a LOT longer and be cheaper in the long run.
