CGW 49793 5" Dia 100-Grit Gold Aluminum Oxide PSA DWT Sanding Disc

The CGW 49793 5" Dia 100-Grit Gold Aluminum Oxide PSA DWT Sanding Disc is a pressure-sensitive adhesive (PSA) abrasive disc designed for fast, efficient material removal on a variety of metal and alloy surfaces. This 5-inch disc utilizes a gold-weight, tear-resistant backing paired with stearated paper and a heat-treated aluminum oxide grain, all bonded with a full phenolic resin. The combination creates a uniform scratch pattern while delivering a consistent cut across the disc’s life, helping maintain smooth finishing characteristics on workpieces.

Key construction features include an open coat design, which exposes more abrasive grains to the workpiece for aggressive initial cutting and extended life, and a C-weight grade backing that supports durability during routine sanding and stock removal tasks. The 100-grit size is suitable for medium-fine finishing and deburring operations, offering a balance between material removal rate and surface finish. The PSA backing enables quick, tool-free attachment to compatible hubs and sanding machines, reducing downtime between discs.

Typical applications encompass general metal fabrication, maintenance and repair tasks, and light deburring where a uniform scratch pattern and reliable cut rate are valued. Consider pairing with appropriate 5" sanding plates and compatible dust collection systems to manage debris generated during operation. Each disc is packaged individually, with the ability to order larger quantities in box sets for bulk use in maintenance shops or production environments. The disc specifications provided here—size, grit, grain type, and PSA format—define compatibility and expected performance within standard 5" PSA sanding systems.
