Question: are dremel and rotozip bits interchangeable?
Answer: The tools have different motions, and the Dremel bits aren't likely to work well with the Rotozip. There is some overlap in their bit sizing, though. The Dremel uses bits from 1/8 inch down to a tiny 1/32 inch. The Rotozip can use 1/8″, 5/32″ and 1/4″ bits.
