Router tool5/7/2023 ![]() ![]() This dust is a respiratory hazard, even in benign materials. The cutter edge angle is blunt, approaching 90°, and so a Type III chip forms, with waste material produced as fine dust. Owing to inertia at these high speeds, the normal wood cutting mechanism of Type I chips cannot take place. As these materials are weak in small sections, routers can run at extremely high speeds, so even a small router may cut rapidly. ![]() Routing is properly applied to relatively weak and brittle materials, typically wood. Chip formation is different, so the optimal tool geometry is different. Routing and milling are conceptually similar, and end mills can be used in routers, but routing wood is different from milling metal in terms of the mechanics. Modern plunge router showing dust extraction tube Routing is a high speed process of cutting, trimming, and shaping wood, metal, plastic, and a variety of other materials. Modern routers are often used in place of traditional moulding planes or spindle moulder machines for edge decoration (moulding) of timber. įurther refinement produced the plunge router, invented by ELU (now part of DeWalt) in Germany around 1949. Carter, and marketed an 18000 RPM electric hand router similar to modern routers. In the 1930s, Stanley Works acquired a line of portable routers from Roy L. In 1915 Oscar and Rudy Onsrud produced an air-powered router, which they referred to as a Jet Motor Hand Router. The early electric routers were quite heavy, and only nominally "portable". The first portable power router was patented in 1906 by George Kelley and marketed by the Kelley Electric Machine Company. Barnes patented a reversible rotary cutting head in 1889. Rotary tools can also be used similarly to routers with the right bits and accessories (such as plastic router bases).īefore power routers existed, the router plane was often used for the same purpose.Īn incremental step toward modern power routers was the foot-pedal operated router, such as the Barnes Former/Shaper, available in 1877. Although it is designed for trimming laminates, it can also be used for smaller general routing work. The laminate trimmer is a smaller, lighter version of the router. There is also a traditional hand tool known as a router plane, a form of hand plane with a broad base and a narrow blade projecting well beyond the base plate.ĬNC wood routers add the advantages of computer numerical control (CNC). Some woodworkers consider the router one of the most versatile power tools. They may be handheld or affixed to router tables. Routers are used most often in woodworking, especially cabinetry. It routs (hollows out) an area in hard material, such as wood or plastic. The spindle may be driven by an electric motor or by a pneumatic motor. The router is a power tool with a flat base and a rotating blade extending past the base. ![]()
