flap wheels are typically used in metal fabrication and welding applications especially when you need a conformable product that can grind and polish intricate shapes and contours. A continuous series of individual flaps work to provide a uniform finish as the flaps wear away to expose fresh abrasive. Three mounting options are available to ensure our flap wheels can fit a variety of different machines.Each grit flap comes in contact with the workpiece at a slightly different angle, which prevents scratches. Because abrasive flap wheels conform to the shape of the surface material, they are commonly used to finish complex shapes and tight contours on a workpiece. Flap wheels attach to grinders, drills, impact wrenches, or handheld rotary tools. T27 flat shape mainly used for grinding flat surfaces, most efficient when used at a 0-15 degree angle T29 Conical shape provides an excellent angle for contonur and edge grinding, best at a wider angle of 15 to 25 degree We p…
