Dwyer, as someone mentioned, a file will take down the disk and remove
the grooves, but you will lose considerable disk material in the process.
However, I considered the grooves to be a good thing with the 2" wheel
on the die grinder which was used almost exclusive for deburring the
edges of sheet stock. If the die grinder is held less than perpendicular
to the edge of the skin, and the skin edge placed in a groove, both
sides of the edge can be deburred in one pass. The groove keeps the
wheel from jumping off the edge (just be careful at the corners of the
skin!). I ended up with some pretty weird-shaped disks but they were
always useful for quickly deburring edges.
Good luck with your project!
