The CGW CGW51059 5-inch diameter sanding disc is a premium PSA (pressure-sensitive adhesive) abrasive designed for film-based applications. The disc uses aluminum oxide grain on a film backing, offering a consistent, smooth finish for dry or wet sanding tasks. Its 5" size and PSA mounting make it compatible with standard disc-adhesive hubs, enabling quick changes during surface prep or finishing work. The film backing is described as strong yet pliable with a .003 inch Mylar layer, which helps resist tearing and provides rigidity for even sanding pressure. This construction is positioned to deliver longer disc life and more stable performance than traditional paper-backed discs, contributing to lower disc consumption in appropriate applications.
This product is specified as 320-grit on a 5" disc, with the film hardness and design intended to extend wear life and improve finish consistency. The packaging indicates a unit count of one disc with a box quantity of 100 discs per package, suitable for bulk use in maintenance, repair, and operations environments where frequent disc changes are common. When selecting discs, users should consider the wet/dry capability of film-backed abrasives and the need for a finish-grade surface, especially on softer substrates where film backing can reduce loading and heat buildup.
In practice, this disc suits general surface preparation, deburring, and finishing tasks on metal or prepared substrates where 320-grit is appropriate. Proper handling includes inspecting adhesive backing for secure attachment prior to operation and selecting the correct pad or backing system to ensure even contact with the workpiece. For those ordering in bulk, note the 100-disc box quantity to plan inventory and cost per disc accordingly.
