CGW 42873 is a snap-on style flap disc designed for high-speed material removal on rotary tools. This 4-1/2 inch diameter, 7/8 inch arbor/flange size Type 29 disc features 80-grit PSG Ceramic grains, which are engineered to stay sharper longer for cooler cutting and extended performance. The PSG Ceramic formulation is aimed at delivering faster material removal with improved durability compared to conventional aluminum oxide and zirconia options, making this disc suitable for demanding grinding applications on metal surfaces. The XL construction implies an expanded abrasive surface area, which can contribute to sustained productivity in professional settings where consistent cut rates are important.
The disc is sized for compatibility with common 4-1/2 inch angle grinders and similar compact tools that use 7/8 inch arbors. Type 29 concave faces are typically preferred for beveling and edge work, while the 80-grit rating indicates a balance between material removal and surface finish. As with all flap discs, performance depends on appropriate mounting, tool speed, and workpiece stability. It is important to verify the grinder’s RPM compatibility with the disc’s specifications and to follow standard PPE and safety practices during use. The packaging indicates a per-disc quantity with box quantities of 10, which may affect procurement planning and inventory turnover.
