Flap discs are an excellent alternative to grinding wheels when your project requires a nicer finish. While grinding wheels can gouge the metal and leave an uneven surface that may show through plating or painting, flap discs produce a smoother finish for a more polished finished product.

Unlike traditional flat sheets, flap discs are made of layered abrasive flaps. This means that as the flaps wear away they reveal new grain underneath, increasing productivity and diminishing grinding and finishing time and costs by combining grinding, blending, and finishing into one step. They are also easy to use, quieter, and offer reduced vibration, minimizing operator fatigue.

SAIT provides an entire line of flap discs in a number of varieties from backing shape and type to density. Conical shape discs feature a built-in angle for increased contact area and are best used for edgework and contoured surfaces while flat shape discs are better for miter joints and corners and leave a smoother finish. SAIT fiberglass backings put their flap discs among the safest on the market due to custom engineering using more fiberglass than competitors to create backings that are lighter and will not splinter or smear. Their plastic backings are non-scratching, resistant to extreme temperatures, and, depending on the type of plastic, are able to be trimmed to expose more abrasives material.

SAIT has worked to develop their flap discs into an industry-leading product through careful testing and research. By implementing more and larger flaps than market competitors as well as formulating a special adhesive system, SAIT offers flap discs that increase both performance and safety while outlasting opponents’ product life.

As with any welding project, certain materials may require different discs. Do your research carefully and be sure to visit Weldfabulous.com for all your welding supply and equipment needs!
