Removing material to create a decorative edge or decorative pattern in wood can be difficult to do if you dont have a guide for your rotary tool. The Dremel high-speed rotary tool fits easily into the 335 Plunge Router attachment to act like a mini-router with the characteristics of a full-size plunge router. This attachment is perfect for small scale plunge routing on all types of projects. The Plunge Router attachment offers fine adjustment for precise routing depth and a two-post design for greater control. This attachment is perfect for forming decorative edges, cutting straight slots or routing freehand. It features a plunge lock-in handle for fast and easy plunge locking. Two depth stops with quick release provide rapid adjustment of routing depth which is extremely helpful when making progressively deeper cuts. The edge guide is used for shaping edges, cutting rabbets, dadoes, mortises, tongues, grooves, slots and chamfers. The circle cutting guide is used for cutting circles in wood, plastic, drywall, plaster, ceiling tile, and vinyl siding.
