Can these felt polishing discs be washed and reused for multiple projects or should they be discarded after one use?
We recommend replacing these felt polishing discs regularly to maintain optimal performance. While they can technically be washed and reused, doing so may compromise their effectiveness over time.
The Standard Abrasives™ Quick Change Felt Polishing Disc is a sanding disc made with nonwoven felt fibers. These fibers are soft, pliable, and elastic, similar to cotton. The spongy and responsive nature of these felt fibers prevents the abrasive from gouging or denting the substrate. This makes it a great option for the final step in a sequence, as it helps the workpiece shine without significantly altering its dimensions. Its light scratch requires light pressure, so users can achieve a desirable finish without too much operator fatigue.
When working with a rough or scratched metal part, users will often begin with an aggressive abrasive, like a Surface Conditioning Disc, to remove unwanted burrs and contaminants from the substrate. The Standard Abrasives™ Quick Change Felt Polishing Disc helps seal the job by delivering a final polish. It's great for polishing a variety of metals like aluminum, stainless steel, brass, and chrome. In addition to the nonwoven felt fibers offering superior flexibility, gaps between the fibers allow swarf to escape. This added benefit prevents the abrasive from clogging with debris, prolonging abrasive service life.
Sometimes, users will apply a buffing compound to help smooth out the surface. Gaps between nonwoven fibers on the Standard Abrasives™ Quick Change Felt Polishing Disc help hold buffing compounds and distribute the substance evenly over the surface. It's important for operators to use compounds sparingly and follow accompanying instructions, because too much compound could saturate the workpiece and impede abrasive effectiveness. Striking a good balance between abrasive and compound is key.
Quick Change AttachmentAvailable in a range of sizes, the small diameters of some of these polishing discs render them useful for tight surface areas – nooks and crannies that might otherwise be hard to tackle. The Standard Abrasives™ Quick Change Felt Polishing Disc features Quick Change TS and TR fastening systems. TS is a standard metal eyelet and TR is a nylon threaded male (screw type) hub. These attachment systems help speed the process and make for easy swap out of discs. Once the disc is attached to its matching holder pad, it can be used with a rotary tool.
Altogether, this Standard Abrasives™ Quick Change Felt Polishing Disc is a good abrasive for final polishing and finishing. It helps revitalize lackluster surfaces and makes the workpiece shine.
