These accessories continue to be OIS® compatible and fit existing tools, as well as the next generation of high-performance Starlock® tools. Bosch multi-tool accessories are Swiss made for precision accuracy and long life in the most demanding professional applications. Bosch has a heritage of innovation – including the SDS-plus® and SDS-max® shank systems for concrete hammers and the T-Shank professional blade standard interface for jig saws. The Starlock® interface is the new professional standard in oscillating multi-tool systems. Review: Worlds fastest box cutter - Perfect tool for breaking down lots of cardboard.
