BOSCH Starlock with the new 3D mount for woodworks

Starlock – the New BOSCH Multi Tool

Tighten up and power up

Switch to Starlock for a new dimension in powerful versatility

Starlock: say goodbye to OIS.

Starlock: 3D accessory mounting – 100%
power transfer efficiency.

Starlock: better performance and longer life.

Starlock: the most versatile multi-cutter accessory system ever.

What is Starlock?

Starlock is a superior oscillating multi-tool system whose key benefits stem from much firmer accessory attachment. Its 3D mounting interface increases power transfer and enables a greater range of applications. In simple terms, the 3D shape of a Starlock accessory’s base plugs very tightly into a correspondingly shaped socket in the Starlock-compatible tool.

Why upgrade to Starlock?

Starlock’s tighter-locking 3D interface is a massive improvement on the old OIS mounting system, whose pins are looser and break more easily. Its main advantages are:

  • 100% power transfer – for higher speed, effectiveness, precision and energy efficiency.
  • Longer-lasting tools and accessories.
  • Greater versatility with a wider high-quality accessory range.
Explore the multi-tools
Oscillating multi-tools use a rapid side-to-side motion which allows accurate, highly controlled cutting, grinding, scraping and sanding – often in confined spaces which a rotating tool cannot reach. Each Bosch Professional model is ergonomically designed for comfortable, effective and versatile operation in a variety of tricky situations. A choice of power and equipment levels is offered to match the demands of different users.
