WEBJul 16, 2008 · Hello. I've been using a 3/8 ball em in alum. It seams like 10% of the diameter is a good roughing step over. I'm going to try 5% step over for finishing. 3% of em diameter gave a good finish on a 3 degree surface. It is easier for my brain to use % of em rather than scallop height. Last edited: Mar 6, 2009.
