The DELTA GR275 6-inch Variable Speed Grinder with Tool-Less Change incorporates three different wheels for sharpening, grinding, and buffing. It features a 2.5 Amp induction-type motor for powerful performance, and has a variable speed of 2000 to 3450 RPM for a fine level of control depending on the materials you are working with. The white sharpening wheel is used for sharpening tools and chisels, and its tool rest has a drill bit rest milled into the surface so you’ll get the correct angle on the tip at all times. A nut and tool-less wheel cover makes changing wheels quick and easy. The base is made of cast iron for durability and stability. An independently switched 40-watt work lamp with a flexible goose neck illuminates the work area while you’re working. A full-size safety shield is clear and has thumb screws for easy adjustment.
