Sorry PWC. I’m trying to help you. But my posts continue being targeted & deleted because of bias.

SGW, I too like carbide and have a diamond wheel for lathe tooling but when my carbide end mills and drill bits bite the dust they are less recoverable that their less fragile counter parts.

I suppose if money/longevity wasn’t a concern I would use nothing but the best but since I still have to bend over to get my whiskey vs reach up, I just get what works the best per dollar spent.

Yes, back in the day when I was in the toolroom, I had access to the tool & cutter sharpening equipment. We used borazon and diamond impregnated cup wheels on a Cincinnati No.2 grinder for the endmills. I sorta miss those days when I could do my own split point drills and carbide tooling. Never had any issues with the end results.
Now, I know what you mean, as tooling costs for good tooling have gone up quite a bit, to the point for me, that it pays to send those out to be done.

I read, decades ago, Roy Dunlap's suggestion of creating a small pyramid of sulfur atop the to-be-drilled location and lighting said sulfur. Apparently hot enough to kill the case hardening. Give this a try,
