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. The Starlock® interface is the new professional standard in oscillating multi-tool systems.
