Flap Wheels With Shaft

Flap Wheels with shaft are made of multiple abrasive sheets attached to a core for fabricating, deburring, cleaning, polishing, and finishing jobs in metalworking applications. The sheets wear away during jobs, constantly exposing fresh abrasive coating to provide an even finish. Each grit flap comes in contact with the work piece 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 work piece. Flap wheels attach to grinders, drills, impact wrenches,or handheld rotary tools. They are either pre-mounted on a central hub, or unmounted for attaching to a compatible arbor.
