Are these grinders useful?

These grinders are part of my staking set. Are they useful for watch repair?

They are counterbores, for creating a sink for cheese head screws to sit down flush with a plate or bridge when the screw is tightened down. Would get more use if you were making custom/replacement bridges rather than repair unless maybe if you needed to replace a screw with a bigger one because the plate threads were stripped. Probably not the only use in repair but I’ll leave comments to folk that know a lot more than me (not hard for sure) as to any other uses.

You can use them for milling down a replaced, too thick brass bushing.

Did you see the Bergeon price for a set?

But if I think about it, and to be really honest: they are of no use at all. Dispose them, you know my adress

Thanks for the replies! So i‘ll try to sell them. The earning will be invested in useful punches.
