Standard Abrasives™ Buff and Blend HP Disc, 850508, 4-1/2 in x 1/2 in A VFN, 10/Pac, 100 ea/Case

The Standard Abrasives™ Buff and Blend HP Disc efficiently performs 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, making it a good starting point 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.

The 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, you may upgrade to one of our Standard Abrasives™ Buff and Blend High Strength (HS) Discs. Quick Change discs are available separately.

?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.

• Tough HP material is stiffer and more tear-resistant than GP material and is well-suited for edge deburring and metal removal
• Aluminum Oxide cuts sharp, helps produce a consistent scratch pattern, and works well on ferrous and non-ferrous metals
• Pliable open web removes burrs and surface contaminants without gouging the substrate
• Open web is load resistant, limiting buildup of debris that can clog the abrasive center hole discs come in a range of medium to large sizes to meet many different project specifications
• Red discs contain aluminum oxide, very fine (VFN) grade abrasive
