Making threaded hole in O1 steel prior to hardening

[klaas0639]

For a wood working project, I want to make specially shaped chisels from O1 steel. To fix these small chisels I want to make threaded holes in it (diameter 5 mm). Can this be successful or will the thread seriously be affected by the hardening process (corrosion or what so ever).

kind regards

I'd have an experiment with a test piece - I would be worried about distortion in the heat treatment process.

No problem at all, I made a spokeshave blade the same way.

And their is no way you are going to be able to tap the threads afterwards.

an M5x1.25 threaded hole is unlikely to distort during heat treating (maybe if it was a something crazy like an m12x1 or something large and very fine). crack on with it.

Some anti-scale compound on the thread before hardening would help to keep it clean

Thanks a lot. I will give it a try.
