Are SDS and SDS-plus bits the same?
The short to your question is “yes”. I found myself researching the same question a few days ago and found that the real difference is between SDS/SDS Plus and SDS Max. I don’t recall the exact dimension now, so I won’t try to quote it, but the Max is a larger size. The I found was enough to tell me I used SDS (SDS Plus), and those were the bits I needed to buy. Once I knew that, I didn’t need to remember the size of SDS Max…they were too big for my drill. Last point, SDS Plus is sometimes shortened to SDS+.
