Not every shaping, trimming, or grooving job calls for a sumo-size router. For small jobs there are mini ones, called laminate trimmers or trim routers. Originally devised to cut off excess plastic laminate at the edge of a countertop, these spinny minis are increasingly being used to shape wood. The tool accepts standard 1⁄4-inch shank bits and can be operated with one hand, leaving the other to steady the workpiece. Light and maneuverable, trim routers are ideal for excavating hinge mortises, forming decorative beaded edges on shelf boards and easing the sharp edges of corner trim. Weighing in at just 3.3 pounds, the latest model from Bosch offers a variable-speed trigger, an improved grip, a muscular 1-hp motor and a blistering top speed of 35,000 rpm.
