Enjoy optimum power and control with the 6911 from Porter-Cable. Featuring a helpful trigger switch that prevents you from having to look away from your work this base is a pleasure to hold and handle. During careful edging work you'll appreciate the safe and secure balance of weight afforded by the D-handle and side knob and shifting both forward and backward is always smooth and stable--never worry about things tipping or toppling over. Precision and accuracy are also guaranteed thanks to the micrometer ring circling the base--it allows you to make adaptations to within 1/64 of an inch. The 6911 is compatible with Porter-Cable router motors no. 6902 and 6912.
