SDS Plus versus SDS Max?

The SDS system was originally developed by Bosch as the “Steck-Dreh-Sitz” system. Later it was renamed as the “Special Direct System” which is how it is present-day named. The SDS system is a professional drill bit system that connects a masonry bit to a rotary hammer and it makes exchanging or placing a drill bit very easy.

There are 3 versions of the SDS system.

  • SDS (The first SDS system invented by Bosch)
  • SDS Plus (The improved version of the first SDS system)
  • SDS Max (The most powerful SDS system on the market)

Note that the standard SDS version is almost completely replaced by the SDS Plus version.
