Flap wheels 80 x 50 x 6 mm, P 40, made of standard corundum. These flap wheels are designed for machining profiled workpieces, internal surfaces, and narrow, hard-to-reach places. They are especially suitable for radial use and ideal for smoothing, derusting, fettling, and deburring. They are also effective for rough grinding and surface treatment of steel, as well as matting and surface grinding.
