Added Stiffness for Lightweight Deburring and other Moderate Applications We designed the Standard Abrasives™ Buff and Blend HP Disc to efficiently perform light deburring and aggressive cleaning on a variety of metal substrates: ferrous and non-ferrous metals, aluminum, high nickel and stainless steel. The tough nylon web offers sustained performance and leaves a consistent finish on the workpiece, resulting in little to no rework. The very fine (VFN) grade abrasive contributes to a nice clean finish. This disc features aluminum oxide mineral, which cuts sharp and is friable, fragmenting under heat and pressure to reveal sharp cutting edges during use. Among the four Standard Abrasives™ Buff and Blend materials, HP material is moderately stiff, durable and aggressive, and we recommend starting here for deburring applications. Its non-woven construction responds to contours and extrusions while minimizing gouging or marring of the part. If desired, discs may be ganged on a shaft to form a wheel. Durable Disc Accommodates Edges and Extrusions Our HP Disc is a smart choice when you need to remove part lines from small castings, small burrs from threaded pipes, burrs from aluminum extrusions or die cast flashing, or heavy surface oxidation. Its durability results in a long service life, helping to reduce the need for replacements. Moreover, the sturdy material stands up to edges and extrusions, minimizing edge fraying and grain shedding. If greater durability is desired for heavier-duty applications such as edge deburring, we recommend that you upgrade to one of our Standard Abrasives™ Buff and Blend High Strength (HS) Discs. Quick Change discs are available separately. 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 dull or blunt mineral. Standard Abrasives™ Buff and Blend products deliver a consistent cut and finish - part after part.
