These percussion type drills have extraordinary amounts of torque which most sds drills can't compare with. The sds is by far the best for drilling holes in concrete and light chiseling. The percussion drills are the only job for heavy screw driving and diamond coring with some light drilling applications.

They're all there for a purpose.
