SDS Plus or SDS Max — which fits my rotary hammer?
| SDS Plus | SDS Max | |
|---|---|---|
| Shank diameter | 10 mm | 18 mm |
| Typical hole range | 4-26 mm | 12-52 mm |
| Hammer class | 2-3 kg tools | 5-11 kg tools |
| Typical jobs | Anchors, 1/4-3/4 in holes | Core drilling, breaking, large anchors |
| Common mistake | Buying Max bits for a Plus tool | Buying Plus bits and expecting speed |
Check before you buy: the collar of the chuck, not the drill body. A tool that takes SDS Plus has a spring collar about 25 mm across; the Max collar is visibly larger and heavier.
Also worth knowing: an SDS Plus bit will not fit a keyed chuck without an adapter, and the adapter gives up most of the hammer action.
