SDS-Plus vs. SDS-Max vs. Spline Drive – Hammer Drill Bits

Jan 22, 2009 · The most common point of confusion is the different tool capacity rating in the titles. For instance Bosch has a couple SDS-Plus Bulldog hammers; one is a 1" SDS-Plus & the other is a 1-1/8" SDS-Plus. This inch rating refers to the solid drilling diameter capacity or basic power of the drill, not a different size SDS-Plus shanks.
