## 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. So far I've used it to break down heavy duty shipping boxes for a couple of days and it is as sharp as ever. Fits perfectly with my little Bosch 12V oscillating tool.
Review: Cut like silk like butter - Worked like a charm to remove caulk from around my brick - cut it like butter.

### ⭐⭐⭐⭐ Good Performance but Expensive.
*by I***P on April 10, 2026*

5 stars for performance. 4 stars for price/value. These blades are good, but should last a bit longer. We use this blade for removal of dried hard but brittle tile adhesive. Stardock is a superior system. Bosch and Anazon should have a accessory Sale every now and then.
