Electronically varies the speed of your router. This means you’ll have less burning, tear-out, noise and tool wear, and safer use of large diameter panel raising bits. Use it with your router, or any shop tool that has a motor with replaceable brushes. You'll get full horsepower and torque at all speeds—from 0 to full RPM. Works on routers up to 3 HP and/or 15 Amps. Features a replaceable fuse for circuit protection, variable speed dial, 3-position speed switch (variable-off-full) and belt clip.
NOTE: This will not work with slow start routers.
