The Bosch® StarlockPlus® oscillating multi-tool features the Starlock® next-generation three-dimensional 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 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 18-volt motor offers better efficiency than previous-generation 18-volt motors for increased power and runtime, offering performance comparable to the corded Bosch® GOP40-30 StarlockPlus®. The motor delivers a top speed of up to 20,000 oscillations per minute, and the tool provides a 2.8-degree 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 pounds, this light and ultra-compact tool reaches tight spaces, provides comfortable ergonomic grip zones, and has an LED light for illumination in dark work areas. It 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. This is a bare-tool kit; the battery and charger are sold separately.
