From Amazon: The Bosch 1613AEVS is a reliable plunge router with a quiet 2-1/4-horsepower motor that delivers a soft start, consistent performance, and variable speeds from 11,000 to 22,000 rpm. The tool also features a number of creature comforts, including ergonomic handles, convenient controls, a smooth plunging action, and fast, precise bit-depth adjustments. Thanks to Bosch's Constant-Response Circuitry, the 1613AEVS always maintains a constant rpm under load, even when running a bit through knotty stock. An easy-to-set knob with six presets controls the router's speed, while an onboard chart lets you know how many rpm the tool is delivering at each level. And, as with other Bosch routers, the 1613AEVS is designed to keep the bit perfectly centered in the router base to ensure more accurate cuts in templates and jigs. --Carl Thress
