The StarlockMax Oscillating Multi-Tool Kit supplies a tool that features the Starlock next-generation 3-D tool-accessory interface. This interface provides best-in-class accessory grip, which in turn generates extreme force transmission produced by the 5.5 Amp motor. 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. This tool delivers a top speed of up to 20,000 oscillations per minute, and the tool provides a wide 3.6° oscillating arc, for greater productivity in cutting, grinding, scraping and other tasks. The no-touch blade-change system makes it easy to attach, remove or reposition blades.
