Flap Disc Sanding Wheel , Iran
Flap discs consist of radially arranged abrasive cloth or non-woven flaps. They are manufactured using aluminum oxide or silicon carbide grains in grit sizes 80 to 600. Standard diameters range from 40 to 150 mm, matching tool rotational speeds. The central connection typically uses replaceable M10 or M14 arbors. Each disc contains 30 to 100 flexible flaps with variable density. The recommended operating speed is between 4500 and 12000 RPM for different diameters. This product is designed for surface finishing, edge blending, and rust removal.
The disc structure creates an effective contact area with the workpiece. The flexibility of each flap reduces localized heat and increases product life. These discs can be mounted on hand drills and stationary machines. Optimal working pressure is adjusted between 3 and 10 Newtons per square centimeter. Uniform flap wear ensures finishing precision up to Ra 0.8 microns. The tensile strength of the flaps typically exceeds 50 Megapascals. Premium grades feature heat-resistant epoxy resin adhesive rated up to 200 degrees Celsius.You can order and buy Flap Disc Sanding Wheel from Iran by contacting us through whatsaap and email.

Grit Grades of Flap Discs
The grit grade hardness degree of a flap disc is determined by the size and density of abrasive grains. The main grades include Coarse, Medium, Fine, and Very Fine/Extra Fine. Coarse Grit 40-80 is used for rapid removal of heavy material, weld seams, and large burrs on metals. Medium Grit 100-150 is applied for surface preparation, leveling, and removing coarse grind marks. Fine Grit 180-240 is suitable for final finishing, removing fine scratches, and creating a smooth surface before painting. Very Fine Grit 320 and above is used for polishing and final gloss on metal surfaces and some polymers. Selecting the appropriate grade depends on the material type, preceding and subsequent operations, and desired surface quality. Combining different grits in a single flap disc is also available for progressive efficiency.
