Product Description
The Bosch GOP18V-28 18V StarlockPlus® Oscillating Multi-Tool Bare Tool features the Starlock® next-generation 3-D tool-accessory interface. This provides outstanding 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 3-D 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 reposition blades. The EC Brushless 18V motor offers better efficiency than previous-generation 18V motors for increased power and runtime, offering performance comparable to the corded Bosch GOP40-30 StarlockPlus. The 18V motor delivers a top speed of up to 20,000 oscillations per minute, and the tool provides a 2.8° 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. At only 2.7 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. The GOP18V-28 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.) It is a bare-tool kit; the battery and charger are sold separately.
