Durable and Heat-Resistant

Ideal for light deburring and blending applications where the final finish is important, the Standard Abrasives Surface Conditioning Flap Disc offers a fast cut and consistent finish in just one step. This flap disc is made from a non-woven nylon material that is highly durable and resistant to loading, ensuring a long-lasting performance. Its heat-resistant open web design makes it an excellent choice for use on aluminum, stainless steel, and titanium.

Recommended Applications

This non-woven aluminum oxide product provides an excellent solution for various applications such as deburring, edge breaking, blending, cleaning, finishing, and polishing. It is particularly effective after traditional grinding with a Resin Fiber or Flap Disc. Use it to deburr milled surfaces and edges, prepare for anodizing, blend weld seams, remove flash and parting lines, and eliminate scratches or weld discoloration.

Engineered for Single-Step Efficiency and Extended Utility

Surface conditioning flap discs are three-dimensional discs with overlapping layers of non-woven, scrim-reinforced flaps that fan out from a central hub. This unique design ensures that fresh abrasive mineral is continually exposed for a fast cut, while the cushioning of the flaps creates a consistent and blended finish. Unlike coated discs, flap discs can deburr and finish in just one step, saving time and costs in various applications. Additionally, their overlapping construction allows for more abrasive material to be loaded onto the cutting surface, resulting in a longer lifespan compared to typical discs. The flexibility of flap discs enables them to easily follow curves and contours, reducing gouging and enhancing operator comfort.

Using a Flap Disc

Flap discs are designed to be used on a right angle grinder. Those with a 7/8 center hole can be securely attached to a right angle sander using a compatible disc retainer nut (sold separately). Alternatively, flap discs with a 5/8-11 internal thread can be mounted directly onto tools with 5/8-11 EXT threaded shafts.

The Standard Abrasives Surface Conditioning Flap Disc features a Type 29 conical profile. The angled flaps provide more aggressive cutting action, making this profile ideal for stock removal and achieving faster results on edge work, flats, and contours.
