Diamond wheels for tungsten work on HF 3" mini grinder

[R-mm]

I know a lot of people use the HF 3" mini grinder as a dedicated tungsten electrode grinder. I have one but can't easily find suitable diamond cutoff / grinding wheels. Can anyone recommend direct fit wheels ?

I use this circular saw 4" diamond wheel on the side of my bench grinder. It's great and no dust.

I have the wheel from their rotary grinding wheel set on mine. Works perfectly.

I did something similar. I bolted the motor of the circular saw blade sharpener to my welder cart. Works great.

Thanks. To confirm this fit right up to the 3" mini grinder? I'm asking because some are discussing another solution but I already have the mini grinder and intend to use it.

It has been a while, but I believe I had to enlarge the hole in the wheel to the correct size.

I just use a belt grinder for the tungsten sharpening... but I do have that mini grinder semi dedicated for tungsten, it's a crappy mini grinder for that job. It works ok.
