Product Spotlight: FLAP WHEELS & BELTS


Small abrasive flaps are projected and bonded to a central hub to create Flap Wheels. Available in mounted or unmounted, Flap Wheels are designed for light finishing, deburring, and flash removal. Most wheels are X-weight aluminum oxide cotton cloth. Exceptions to this would be J-weight cloth for increased flexibility, and silicon carbide for special applications.

Mounted flap wheels are available with a ⅛” or ¼” straight shank or a ¼-20″ male threaded shank. They are generally 3” or less in diameter and used on portable tools.

Unmounted flap wheels flaps radiate outwards from a central core, have an arbor hole, and are mounted onto a spindle with flanges. They are 4″+ in diameter and used on stationary tools.

ARC’s flap wheels add additional margin to your bottom line with their exceptional value-to-performance ratio.



Belts are used in multiple applications from fine finishing of stainless steel coil to heavy stock and weld removal. In general heavy weight Y-weight are used for stock removal whilst flexible J-weight is used for fine finishing and contour work.
