Mounted Flap Wheels
Advantages of Mounted Flap Wheels
Versatile Access to Complex Areas
Mounted flap wheels are designed to reach tight spots, internal holes, grooves, and contours that flat discs cannot, making them ideal for detailed grinding, deburring, and finishing in hard-to-reach areas.
Consistent & Uniform Material Removal
The radial or circumferential flap arrangement provides even pressure across the surface, reducing the risk of uneven wear, scratches, or gouging, ensuring predictable and high-quality results.
Flexible & Conformable Design
The flaps adapt easily to irregular shapes, edges, corners, and curves, allowing smooth blending, polishing, and finishing on both flat and contoured surfaces without switching tools.
Efficient Heat Dissipation
The open and flexible flap structure promotes airflow during grinding, reducing heat buildup, minimizing surface discoloration, oxidation, or warping, and extending the life of both the tool and the workpiece.
Various Abrasive Grains
Flap discs are available in a wide range of abrasive grains, each designed to handle different materials and applications effectively. By selecting the right abrasive grain for your application, you can optimize the performance, lifespan, and efficiency of the flap disc.
Zirconia
Zirconia provides longer life and higher stock removal than aluminum oxide. Its self-sharpening feature maintains cutting power during heavy use, making it ideal for grinding, weld removal, and surface prep on steel, stainless steel, and alloys.
Ceramic
Ceramic is durable, self-sharpening, and ideal for aggressive stock removal. It withstands high heat and pressure, maintaining performance longer than other grains—perfect for stainless steel and tough alloys in demanding applications.
Aluminum Oxide
Aluminum oxide is a common, versatile abrasive ideal for general grinding, light deburring, and finishing on mild steel, alloys, and non-ferrous metals. Its low cost and wide usability make it a popular choice.
Calcined Aluminum Oxide
Calcined Aluminum Oxide is a heat-treated Aluminum Oxide with improved sharpness, toughness, and grain density, offering smoother grinding, longer life, and greater durability.
Silicon Carbide
Silicon carbide is sharp and brittle, enabling efficient grinding and smooth finishes on non-ferrous materials. It’s ideal for delicate work on ceramics, glass, stones, brass, bronze, and other soft metals.
Non-woven Abrasive Grit Guide
Learn the differences between coarse, medium, and fine non-woven abrasives. Find the best grit for rust removal, surface cleaning, and precision polishing on stainless steel, aluminum, and other metals.
Coarse_Brown
Coarse non-woven abrasives are ideal for heavy-duty cleaning and surface preparation. They efficiently remove rust, oxide layers, paint, and welding discoloration from metal surfaces. With strong cutting power and durable fiber structure, they maintain stable performance without clogging. Perfect for initial surface treatment, weld cleaning, and pre-polishing on stainless steel, carbon steel, and other metals.
Medium_Red
Medium-grit non-woven abrasives provide the perfect balance between cutting and finishing. Suitable for general-purpose cleaning, deburring, and light grinding, they remove light rust or oxidation while maintaining surface integrity. The flexible design ensures even contact and consistent finish, making them a great choice for intermediate surface preparation before painting or coating.
Fine_Blue
Fine non-woven abrasives are designed for precision finishing and polishing. They deliver smooth, satin-like finishes, effectively enhancing the appearance and surface quality of metals such as stainless steel and aluminum. Ideal for final finishing, blending, and decorative polishing, fine-grit pads help achieve a professional look before the final coating or assembly stage.
Interleaved
Interleaved non-woven abrasives combine layers of abrasive cloth (sandpaper) and non-woven material, offering the perfect balance between cutting power and surface finishing. The sandpaper layers provide strong aggressiveness and fast material removal, while the non-woven layers ensure cool, consistent, and smooth finishing. This hybrid design enhances efficiency—making it ideal for applications that require both effective stock removal and refined surface quality, such as cleaning welds, removing rust, or blending metal surfaces.
Grain Sizes: from Coarse to Ultra Fine
Flap discs are available in a range of abrasive grain sizes, from coarse grains for heavy stock removal to ultra-fine grains for polishing and smooth finishing. The right grain size will help ensure optimal results, whether you're grinding, blending, deburring, or finishing.
Coarse Grains (16-60 grit)
Coarse grains are designed for aggressive grinding. These discs are ideal for tasks that require heavy stock removal, such as removing heavy welds, cleaning rust or heavy corrosion, shaping rough surfaces or edges, and pre-grinding or heavy-duty grinding tasks on steel and other hard metals.
Medium Grains (80-120 grit)
Medium grains offer a balance between aggressive stock removal and surface finishing, leaving a smoother finish than coarse grains.These excel in tasks such as removing burrs and imperfections, blending weld seams and smoothening rough surfaces, general grinding on steel, stainless steel, and non-ferrous metals.
Fine Grains (180-320 grit)
Fine grains are suitable for smoothing surfaces and achieving a finer finish. They are ideal for smoothing weld seams, polishing and finishing on stainless steel, aluminum, and other non-ferrous materials, final surface preparation before painting or coating.
Ultra Fine Grains (400+ grit)
Ultra fine discs are designed for the highest levels of precision and smoothness. They provide an exceptional finish for high-end polishing work, removing the smallest imperfections without affecting the underlying material, leaving a mirror-like finish.
