I’ve been working on a new set of dies for a stamping project and I’m debating between using D2 or O1 tool steel — i’ve read that D2 holds its edge longer but is harder to work with. Has anyone had experience with these materials? I’m looking for insights on edge retention vs. ease of machining, especially for tight tolerances.
I’ve worked with both, and while D2 does hold an edge better, it can be a pain to machine. I found that using carbide tools really helps when working it for tight tolerances. Have you tried any specific tooling for either steel?
When I used D2, I found that a slower feed rate really helped with maintaining tight tolerances, even though it took longer overall. @taylor_h93, have you considered using a heat treatment to improve its machinability?
Choosing between D2 and O1 can be tricky — while D2’s edge retention is great, I remember nearly pulling my hair out trying to machine it for a past project. Have you thought about starting with O1 for those tight tolerances? It can be easier to work with, especially if you’re making multiple dies. @alexis44_m might have some tips on how to transition between them effectively.
I’ve found O1 easier to machine for intricate details, but if you’re set on D2, using carbide tools really helps; have you looked into your heat treatment options?
