The SDS shank is simply pushed into the spring-loaded chuck without tightening. SDS shank and chucks are made to be used for hammer drilling with masonry drills in stone and concrete. The drill bit is not held solidly in the chuck, but can slide back and forth like a piston; it does not slip during rotation due to the non-circular shank cross ...
Developed by Bosch in 1975 for hammer drills, the SDS System uses an SDS Shank which is a cylindrical shank with indentations to be held by the chuck. [3] A tool is inserted into the chuck, and is locked in place until the lock is released. The rotary force is transmitted through wedges that fit into two or three open grooves.
Modern units allow the hammer and rotation functions to be used separately or in combination, i.e., hammer mode, drill mode, or both. When used in the hammer mode, the tool provides a drilling function similar to a jackhammer. [4] Rotary hammer drills have an oil filled gearbox, which allows them to operate durably despite the large forces and ...
