## Questions & Answers

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

**Q: Is there an adapter to use on a 5/8 inch grinder**
A: should use same arbor back flange and securing nut as an ordinary grinding wheel without threaded arbor, usually comes with grinder

**Q: I want to shave a door down about 3/8 inch.  Would this work for the job?**
A: mostly, this is used for grinding metals. To cut 3/8" wood, you need a saw not a grinder.
Thanks

**Q: OK for glazed tile?**
A: 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.

### ⭐⭐⭐⭐⭐ Excelente disco
*by M***S on 25 July 2022*

Lo pedí ya que tenia q lijar algunos tablones de madera, me encantó como se desmpeño, al inicio al tener el grano nuevo es más abrasivo, pero conforme se va utilizando disminuye su abrasivo.
