Up to 4 times better dust extraction than standard sandpaper. Dust can cover everything and makes the sandpaper practically unusable. It penetrates the entire room and is the biggest disadvantage when sanding. However, the Particle Control system has largely solved this problem. Bosch Particle Control ensures that all dust particles are sucked into your vacuum or filter. The Bosch Expert M480 mesh sanding blade is at the forefront of this system: particles move through the open mesh instead of clogging the surface or contaminating the air. This ensures a high level of efficiency and a very long service life. Many experts find it hard to believe that the biggest problem with grinding has been eliminated. It wasn't easy, but it's done. Dust-free sanding with the Bosch Expert M480 sanding net. Simple attachment with Velcro fastener. Disc diameter: 125 mm, grit: 180.
