Big Horn 19661 Brass Router Template Guide for Routers DW616, RF1100, 5615

The Big Horn 19661 is a precision-machined brass router template guide designed to replace Porter‑Cable OEM part 42027. With an inside diameter (I.D.) of 11/32″ and an outside diameter (O.D.) of 7/16″, it provides an exact, controlled offset when following patterns or jigs. Made of solid brass, it resists wear and vibration for reliable long-term use in demanding template routing tasks. It mounts securely to router bases that have a 1‑3/16″ base plate center opening, allowing the bit to cut consistently while the guide rides along the template edge. Ideal for applications like hinge routing, dovetail cuts, stair stringer trimming, and detailed pattern work. This guide is compatible with many Porter‑Cable–style router sub-bases, including those used in routers from Bosch, DeWalt, Makita, Metabo, Milwaukee, and Skil. Its durable construction ensures repeatable, accurate cuts and better control—especially when paired with a template or router jig.
