    Default FMR Electric Grinding Wheel

    Was given a box of grinding wheels today, 5 of them were FMR Electric grinding wheels. A google search only found a New York Times article about them closing, and a .gov link for their pension.

    Anyone know what grit/grade these are?

    White aluminum oxide 54 grit?

    Good bad? Worth using/keeping?3dbe4c6b-f4fe-4e57-a881-97c3ad612991.jpg

    What I can read of the code says Al oxide and 54 grit. The rest doesn't seem to make sense but it is not clear in the pic.If they ring OK then try it out.
