— all SDS-marked chucks are quick-clamping — they do not require additional tools such as wrenches or screwdrivers to install and remove nozzles. SDS Max is a version of this standard that is quite popular among modern demolition hammers. This is due to the fact that it allows the use of fairly large working nozzles — from 20 to 55 mm thick. At the same time, SDS Max is found mainly among models of the light and medium "weight category" (see "Weight").
