Product Description

The Bosch GOP40-30B StarlockPlus® Oscillating Multi-Tool Kit includes a tool that has the Starlock® next-generation 3D tool-accessory interface, which produces best-in-class accessory grip, making it the new professional standard in oscillating tool performance. With more contact surface area between the tool and accessory, the Starlock® interface is a cupped 3D tool-accessory connection that delivers greater torque transfer for an expanded work capacity. The no-touch blade-change system makes it easy to attach, remove, or re-position blades. The professional-grade 4.0 Amp motor delivers a top speed of up to 20,000 oscillations per minute, and the tool provides a 3.0° oscillating arc. A variable-speed dial allows the user to set the optimal speed for the task at hand, and Constant Response circuitry maintains the desired speed under load. This robustly constructed tool has reinforced gearing for more durability, less vibration, and optimal force transmission. At only 3.3 lbs, this light and compact tool reaches tight spaces, provides comfortable ergonomic grip zones, and has an LED light for illumination in dark work areas. It is ideal for flush cuts, such as doorjamb cuts (using various plunge or segment blades). The GOP40-30 provides outstanding versatility – utilizing the many Starlock® and StarlockPlus® accessories to handle flush-cutting, plunge-cutting, sanding, grinding, and many other tasks related to a wide array of materials. For compatibility with StarlockMax® accessories, which perform industrial-grade applications, Bosch offers the GOP55-36 Oscillating Multi-Tool.
