Compatible with a wide range of OIS tools, this blade is engineered for durability, precision, and seamless tool integration. ## Description 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. Review: Worlds fastest box cutter - Perfect tool for breaking down lots of cardboard.
