I bought a flat disc like that and added it to the side of my bench grinder, it works but the angle is sometimes awkward.

However I found
THIS and am thinking I might try one.
I bought one of those flat disk too. You're right; the angle is weird and I don't get parallel groves to the point of the tungsten. So I went back to my Harbor Freight 3" bench grinder with a diamond blade on it. Works really well.

Are you referring to a 3" wheel with a diamond face? What grit do you use?

Here's my set-up I had to drill out the wheels to fit the grinder. Grit? Don't know doesn't say.
The wheels are only 10 bucks.

I rigged up a dedicated grinder using a HFT bench grinder and cabbing (diamond) wheels from Rocklady on ebay, but rarely use it anymore.
For my purposes, I find that just using a 4" angle grinder works fine. I turn it on, set it on the floor, hold it from moving with my feet, and spin the tungstens against the wheel by hand. I don't see all that much difference from the dedicated grinder, and mine goes to I think 800 grit.
If you're trying to TIG on a budget, I think this is one place to save some dough. I definitely can't see spending $$$$ on a tungsten grinder. Maybe if I was tigging unobtainium for NASA, but I'm not...

I found a Liquid Gold grinder used about ten years ago for a pretty good price, I had to get a new diamond wheel and a few other parts to make it right but it does work good. Not so sure I would spend the money to buy one brand new as they are proud as He!! of those things.
