What size arbor bushings does this wheel come with? Seeing a lot of contradictory info.

Each wheel contains arbor bushings in sizes 1/2", 5/8", 3/4", and 7/8"

Is this a 60 grit wheel? It says 'specification: very fine 60.' What does that mean?

The one I bpught is 150 grit. 60 is available but too rough for lathe tools. 60 is more for rotary lawn mowers, dressing struck tools, etc.

Can anyone advise the hardness rating of the 6 x 3/4, 150 grit stone? wheel hardness is rated on a scale from a to z, with a being the softest.

This wheel has a hardness rating of K.

Has anyone experienced this wheel wobble causing a lot of vibration on the grinder machine?

Been My experience that wheel wobble is often an issue with the grinder, though not always. There are some good videos on YouTube that show ways to correct these issues with the grinding wheel if issues with the grinder prove to not be the issue! Ive had no problems with the wheel I purchased.
