The CGW 52820 is a 20-inch diameter PSA sanding disc designed for heavy-duty material removal on cast iron, nickel, and stainless steel. This Y-Weight resin-bond polyester cloth disc features two coatings of grinding aid, which help manage heat buildup and improve abrasive performance on ferrous and non-ferrous alloys when used with compatible grinding tools. The 40-grit zirconia grain provides a balance of rapid material removal with a relatively long service life, suitable for cleaning and deburring operations on larger workpieces.
Constructed as a PSA (pressure-sensitive adhesive) disc, it is intended for quick application and easy changes on compatible backing pads. The 20-inch diameter format is appropriate for wide, high-efficiency grinding tasks, and the Y-Weight cloth construction offers durability and dimensional stability under grinding pressure. The combination of zirconia grain and grinding aid is selected to enhance cut rates while helping to control heat, which can impact workpiece surface integrity and finish when machining metals like stainless steel and nickel alloys.
For best results, use with appropriate tool speed and pressure settings recommended for PSA discs and the specific alloy being processed. The package configuration notes a box quantity of 25 discs, with each disc intended for individual use prior to replacement. Maintain clean backing surfaces and store discs in a dry environment to preserve adhesive performance and grain integrity.
