SpinRite™ router motors are built from the ground up to deliver optimum performance in a router lift or a small shop CNC. It starts with industrial CNC-grade ER20 collets, a carefully machined internal taper on the shaft, and a precision collet nut. These three critical components combine to deliver significantly less run-out than the most popular 3HP class routers on the market. Then, there’s infinite speed control from a low of 10,000 rpm to 22,000 rpm. When you turn the Spin-Rite on, you’ll notice the soft-start feature ramps the speed up smoothly, saving wear and tear on both the router and the lift (or gantry). Once it’s at speed, you’ll notice minimal vibration and 75% quieter operation. It all comes together to deliver a better surface finish, less operator fatigue and longer tool life.
