Flap discs BDX grit size 120

Flap discs wear evenly and release new abrasive grain, making their design ideal for sanding contours and uneven surfaces. They deliver an even finish with a uniform removal rate, especially on aluminum and stainless steel workpieces. Fan sanders adapt to contours and uneven surfaces. They are made of abrasive cloth flaps arranged in a radial pattern around a plastic core and offer flexibility for a smooth surface. For flap sanders, a working speed of 38 – 42 m/s is recommended for the best results. At this speed, only the blade ends touch the workpiece due to the centrifugal force. The result is an improved removal rate and surface quality as well as a reduction in heat generation and tool wear.
