The 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 degree oscillating arc.
