Bosch OSL400K 4 Inch Starlock Bi-Metal Serrated Knife Segmented Blade

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.
