Bosch Starlock® Oscillating multi-tool accessories deliver a three-dimensional fit designed to provide a completely integrated system between multi-tool and accessory. This is a new dimension in torque for oscillating multi-tools. By using a three dimensional shape instead of a flat interface, Starlock® provides the highest torque transfer, reduced vibration, and the ability for higher performance applications. 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.
