For use in power or hand sanding applications, sanding disks come in a multitude of options. Their various sizes to suit different tools or project applications makes allows flexibility when sanding either large areas or smaller detailed works. Sanding pads typically have a hook and loop backing for easy change in and out on both hand pads and power sanders. Other pads may feature an adhesive backing for use with benchtop disk sanders or a locking system for more specific tools.The abrasive grit size on sanding discs relates to the size of grit particle on the pad. This value directly relates to how aggressive the sanding will be when it is used. For rough heavy sanding a lower value is required and for a smoother finish sanding a higher grit value is required. Sanding disc grit materials vary but typically feature glass, metal or ceramic particles.
