The Carbide ER-11 Compact Router is our custom-made trim router packaged for use with any of our CNC routers. We worked with our router manufacturer for a year to develop this router for us. Why buy an ER-11 router? There's only one reason to buy this router over the less expensive Carbide Compact Router: you need to use cutters or drills with a shank diameter other than 1/8" and 1/4".
