What is best way to cut a 1mm o-ring groove to a .75mm depth on a mini lathe.
I'm considering using a small drill bit. Is there a better way to do this?
The machining adventure continues. = )

OD or face?
What's the material?

Consistency is a good thing....unless you're consistently an idiot.
HUH????I'm considering using a small drill bit.

Grinding an appropriate form tool is the correct way to do it...

Grind the desired width into a cutter, I have found that it does not have to be round just grind the end square and chamfer the outside. Here is a picture of one ground for a inside. It is looking down from the top, of course a relief has to be ground on the underside.

Based on the uniformity of the burn marks, that tool looks EDM'd to me....you cheater!

I have frequently used a part off tool for OD grooves since it eliminates a lot of grinding.
Face grooving tools for small diameters require either a lot of attention or a very frail cutting edge. Let us know if you need some pointers.

It's on the outside of the of the piston...
I was considering using a broken drill bit, ground flat. Similar to how people use them to make a boring bar. I was just going to make a 1/4" clamping fixture to hold the bit in my tool post.
Grinding a 1/4" tool bit down to less than 1mm is going to be interesting...
Maybe I'm over thinking it.

No EDM here, just a cheap grinder and about 20 minutes
.....ground by hand - what-everrr (in my best SoCal female voice). It's your story - tell it how you want.
(J/K!!!) - I am in a goofy mood - painkillers are a guud thing!
Good work, Ken. Your patience is obvious. Looks really good.
