Improved Finish and Dust Control on Radiused and Contoured Parts
A flap wheel comes in handy when you’re faced with the challenge of cleaning up burrs and parting lines on radiused or specially shaped parts where coated discs are not conformable enough or do not have the necessary reach. We designed our Standard Abrasivesâ„¢ Aluminum Oxide Flexible Flap Wheel with radiused flaps that, compared to our standard Flap Wheel, provide greater flexibility for improved finishing. The radiused flaps also brush dust away from the contact area for a cleaner work environment.
We offer our Flexible Flap Wheel in smaller diameters for attachment to hand-held tools, and larger diameters for off-hand applications. Some power tools may require an additional reducer bushing or adapter for attaching the wheel.
A broad selection of grades is available to deburr edges, remove flash and parting lines, blend machine marks, apply a linear scratch pattern, or provide light blending, cleaning, or polishing.
Small Wheels Access Inner Radiuses and Maintain Maximum Control
Our wheels with smaller diameters provide access to smaller and harder-to-access inner radiuses or contours on irregular parts. They are especially useful for deburring or finishing the insides of tubing. For these smaller areas, flexible flap wheels provide a softer touch than rolls or bands, which are suitable when more aggressive material removal is required, and produce a softer finish than standard flap wheels.
Our smaller wheels are 1-3? in diameter have a 1/4? steel mandrel or a 1/4?-20 threaded steel shank to enable fast yet secure product changeouts. In each case the steel attachment runs the full width of the wheel center, reducing chatter in the rotation. As a result, you get a smoother finish and the operator maintains greater control of the tool with less pressure.
Large Wheels Supply Broader Coverage
For larger hand tools or off-hand applications, we provide flap wheels in diameters from 3-1/2? to 8? with 1-2? widths. These sizes have a 5/8? or 1? center hole compatible with larger tool arbors. The larger wheels contain more flaps per wheel for faster cutting, increased productivity and longer life.
Durable Wheel, Fast Cut
Aluminum oxide is a popular choice among industrial professionals because of its versatility on different surfaces, fast cut-rate and long life. It is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives such as garnet quickly wear down with use. Aluminum oxide mineral is suitable for a wide variety of materials including ferrous and non-ferrous metals.
