SDS-plus is a 10 mm tool fitting system for drilling and percussive application tools developed by BOSCH in 1975. Today SDS-plus is used worldwide in some 90% of all hammers in the range up to 4 kg. SDS-plus has the following advantages:

- tool-free changing of drill bits/chisels with automatic locking feature

- drill bit locking and torque transmission are separate

- loss-free torque transmission with 60 mm2 contact surface,

- high drill bit quality through chrome-nickel-molybdenum alloy.

SDS stands for Special Direct System.
