PRECISION ABRASIVES 1" X 1" X 1/4" 40 GRIT FLAP WHEEL - 30,000RPM

A flap wheel is an abrasive wheel made from abrasive strips (flaps) radiating from a center hub. Flap wheels come in many different shapes and sizes. The outside diameter of the wheel can range form 1" to 24" and sometimes larger. The hub helps hold the flaps together at the periphery and defines the arbor of the wheel at its center. There are various methods used in holding these flaps to the hub, probably the most common is a glue/adhesive that bonds the flaps together as well as to the hub. There are two basic components to a flap wheel: the hub of the wheel, and the abrasive used in the wheel.
