Moderately Aggressive for Lighter-Weight Applications Our Standard Abrasives™ Buff and Blend Hook and Loop GP Vacuum Disc is a great multi-purpose product for general-duty industrial applications. The dust holes assist with removal of dust and debris for applications such as paint removal or finishing of soft metals such as aluminum or brass. Among the four Standard Abrasives™ Buff and Blend materials, the GP material is the least aggressive and most suitable for light-weight applications. Use it to remove light oxidation, blend minor surface imperfections, clean surfaces prior to coatings, remove small burrs, and perform basic equipment cleanup. This aluminum oxide disc comes in grades of medium (MED) and very fine (VFN). Versatile and multi-purpose, Standard Abrasives™ Buff and Blend GP products work well on a variety of substrates, including ferrous and non-ferrous metals, aluminum, high nickel/chrome alloys and stainless steel. Non-woven construction makes this disc spongy and responsive so that it conforms to workpiece contours or irregularities. When the job requires additional toughness for higher-pressure applications, we recommend using a Standard Abrasives™ Buff and Blend HP or HS Disc. Using a Hook and Loop GP Vacuum Disc Designed with exposed dust holes for use on portable sanders with a vacuum system, the GP Vacuum Disc helps keep the air and workpiece free of dust for a cleaner work environment and work surface. Dust and debris is extracted through symmetrically placed holes in the disc and drawn into a vacuum system connected to the sander (available separately). Hook and loop vacuum discs mount to a hook and loop style holder pad that has compatible dust holes and is the same diameter as the disc. The holder pad (available separately) provides convenient attachment to a random orbital sander. For use with other tools, Buff and Blend discs are also available with quick change and center hole attachments. The Many Benefits of Standard Abrasives™ Non-Woven Products Standard Abrasives™ Buff and Blend non-woven products offer many benefits. Varying Buff and Blend materials help distinguish Buff and Blend products from each other, but all Buff and Blend products have an open web. The open web combines abrasive mineral and non-woven nylon fibers with a resin-reinforced bond. The resin bond securely anchors mineral to the fibers, making for a strong, durable abrasive. Gaps between fibers allow swarf to escape, so the abrasive does not get clogged with debris. Minimizing swarf and debris prolongs abrasive service life and keeps minerals cutting sharper for longer. Nylon fibers won't splinter during grinding, offering a good alternative to steel wool. Moreover, as the fibers break down and fresh mineral is exposed, it reduces the likelihood of the disc smearing the surface. Standard Abrasives™ Buff and Blend products deliver a consistent cut and finish - part after part.
