Abrasive wheels are tools used for cutting, grinding and polishing various materials. Unmounted flap wheels have multiple overlapping flaps of abrasive material arranged radially around a central hub. These abrasive wheels are suitable for blending, deburring and finishing tasks on irregular or contoured surfaces. Unmounted flap wheels come in various grit sizes, allowing for different levels of aggressiveness and surface finish. They are versatile and can be used on metal, wood and plastic. Unmounted flap wheels are typically mounted on a bench grinder or handheld grinder for precision and controlled abrasion.
