I saw a handy tip on YouTube yesterday and tried it out today. Guy was using a brick chisel to knock of backside dross. His video was totally bogus as all his shop equipment was brand new.
But, I tried it today and that tip definitely will save some flap disk wheels. I tried flipping the bevel both ways and it worked best for me with the bevel against the metal surface vs what I show in this pic. I paid $18 at Lowes. It took of 90% of the dross I had today.
