What's the difference between SDS, SDS-Plus, and SDS-Max bits? The drill's chuck style.

So, by way of explanation, SDS and SDS-Plus are the same. No difference. The SDS-Max is a relatively new shank style that only an SDS-Max drill will handle. So, if in doubt, if your SDS drill does NOT say SDS-MAX on it, then it uses the SDS-Plus bits.

We've  listed all the SDS-Plus mansonry bits below. For SDS-Max masonry bits, see our category at LEFT.
