CGW 49779 is a 6-inch diameter PSA sanding disc designed for fast, efficient material removal on metal and similar substrates. The disc features a 120-grit aluminum oxide grain bonded with a full phenolic resin system and a heat-treated formulation, all mounted on a tear-resistant gold-weight paper backing. The open-coat construction promotes rapid cutting and extended life by reducing heat buildup and clogging during use. This combination supports consistent scratch patterns and a stable cut rate across the disc’s life, making it suitable for applications requiring uniform finishing and predictable disc behavior.
The 6" PSA configuration ensures quick, tool-free attachment to compatible orbital sanders, with the adhesive backing providing reliable adhesion during normal operation. The product is described as C-weight (a grading reference for the backing stiffness) with a DOR (Durable Open Residual) characteristic intended to balance resilience and flexibility under typical dry sanding conditions. Each disc is packaged individually, with box quantities listed at 100 discs per box, aligning with production and maintenance stocking needs. The construction specifics—aluminum oxide grain, heat-treated processing, and a full phenolic bond—are cited as contributing factors to the disc’s early cut rate and long service life under standard grinding tasks.
When selecting this disc, users should consider the 120-grit texture as a medium-fine finish suitable for deburring, surface preparation, and blending tasks on metal surfaces. The PSA (pressure-sensitive adhesive) backing requires a clean, smooth sanding pad surface for optimal adhesion and safe removal of spent discs. Maintain appropriate sanding speeds and pressure to avoid heat buildup that can affect finish quality and disc longevity. The disc is sized for common 6" sanding systems, and the 100-count box provides inventory efficiency for fabrication shops or field maintenance teams that routinely service equipment with 6" sanders.
