Deburring inside of EVO diff housing

[Drewpy Dawg]

I'm re-assembling a mechanical LSD rear diff from an EVO. I recall reading that it's a good idea to deburr the edges of the slots that the tabs of the clutch plates and diff gears ride in. I assume it's just a matter of taking off the sharp edge very lightly so everything can move freely without any chance of catching or binding. What's the preferred way to do this? Small sanding drum/roll in a Dremel or die grinder? Or is this entirely unnecessary?

I use 1/2" or 5/8" diameter x 1.5" long sanding rolls on a 4"-5" long arbor on a die grinder. McMaster Carr will have everything you need, or mscdirect, etc.

Perfect. I already have the sanding rolls, arbor, and die grinder. Just wanted some confirmation before I did anything. Thanks.
