Designed especially for stringed instrument work. Our exclusive design provides excellent control when routing for binding and inlays. Our sturdy, compact base is the best way to hold a Dremel for freehand routing, inlaying, widening fret slots, and more. Made of machined steel, brass and aluminum, it features precision cutting depth adjustment with large thumbwheels to eliminate guesswork. Excellent control Easy installation Accurate freehand routing Sturdy, compact, and adjustable Each turn of the large knurled thumbwheels adjusts your Dremel's cutting depth by 0.035" (0.889mm). You can rout an inlay cavity that's precisely compensated for the thickness of the pearl and glue, for less sanding later. Tall twin handles give you excellent control for freehand routing, and you get a good view of your work. There's even a built-in nozzle for attaching a mini air pump to continuously blow away the dust—you'll rout inlay cavities more precisely, for a better fit requiring less filler. The Complete Set includes: Precision Router Base: For sturdy, accurate freehand routing Binding Edge Guide: To cut smooth, clean binding channels up to 3/8" thick Router Bit for Binding: Small diameter is ideal for tight curves Mini Air Pump: Keeps the cutting area free of dust Installation is easy. Simply unscrew the threaded plastic collar on the nose of the Dremel, and screw on the Precision Router Base. Its 3/4-12 thread fits: • Dremel 4000, 400XPR, Professional, MultiPro™ and most corded models made since 1986 • Black & Decker Wizard™ and RTX™ • Our Foredom custom handpiece
