Hi Everyone

I have these drill bits I got from my grandfathers shop and Im not sure what they are. Having a hard time figuring out what there used for.

They don’t drill through wood.

First, they are dull. Second, they are probably for a metal milling machine or drill press.

I agree with the dull part, but isn’t that angle designed for plastics?

with that angle id say used for drilling a form of plastic. the higher angle keeps it from biting too much.

I concur, they dont drill wood because they’re duller than a doorknob !
