Bosch 3/4 in. & 1-1/4 in. Carbide Plunge Blade features Bosch Starlock® oscillating multi-tool accessories that deliver a three-dimensional fit designed to provide a completely integrated system between the multi-tool and accessory. This innovative design introduces a new dimension in torque for oscillating multi-tools, utilizing a three-dimensional shape instead of a flat interface to provide the highest torque transfer, reduced vibration, and enhanced performance for demanding applications. These accessories remain OIS® compatible, fitting existing tools as well as the next generation of high-performance Starlock® tools. Crafted in Switzerland for precision accuracy and long life, Bosch multi-tool accessories are engineered for the most challenging professional uses. With a heritage of innovation including the SDS-plus® and SDS-max® shank systems and the T-Shank professional blade standard for jigsaws, the Starlock® interface sets a new professional standard in oscillating multi-tool systems.
