is it 4-1/2 x 1/4 x 7/8? I notice it is only described as 4-1/2 x 7/8. Pls help. Tks

Yes. 41/2 diameter x 1/4" thick with a 7/8" hole ( bore)

Is there an adapter to use on a 5/8 inch grinder

should use same arbor back flange and securing nut as an ordinary grinding wheel without threaded arbor, usually comes with grinder

I want to shave a door down about 3/8 inch. Would this work for the job?

mostly, this is used for grinding metals. To cut 3/8" wood, you need a saw not a grinder. Thanks

I think it you used it with a variable speed grinder at the slowest speed it would work for cleaning up the edges. For glass I just use a random orbital electric sander with 100 grit, since glaze is essentially glass, I would use caution on a rough grit.
