CGW 42853 4-1/2" x 7/8" Type 29 80-Grit PSG Ceramic Extreme II Flap Disc is designed for heavy material removal and finishing on metal surfaces. This flap disc uses Precision Shaped Grain (PSG) Ceramic grains, which are engineered to stay sharper longer, delivering a cooler, faster cut with improved durability compared to conventional aluminum oxide or zirconia discs. The Type 29 configuration provides a trapezoidal grinding angle suitable for contour finishing and blending, helping users achieve smoother profiles on curved or contoured workpieces. The 4-1/2" diameter and 7/8" arbor size fit common right-angle grinders and compatible mounting setups, supporting efficient workflow in fabrication, maintenance, and repair tasks where metal surface preparation is required.
PSG Ceramic grains contribute to extended tool life and consistent performance by maintaining sharpness through multiple passes, which can reduce cycle times and downtime. The 80-grit rating offers a balance between material removal rate and surface finish, making it suitable for deburring, blending welds, and cleanup work on ferrous and non-ferrous metals. This disc is part of CGW’s Extreme II line, indicating a focus on durable construction and reliable performance under demanding shop conditions. Users should verify grinder compatibility with the 7/8" arbor and observe standard safety practices when operating flap discs at full RPM.
Packaging specifies that each disc is sold individually, with box quantities available in sets of 10, which can help with stocking and reorder planning for maintenance operations. For best results, mount discs securely, follow grinder manufacturer torque recommendations, and use appropriate PPE to protect against dust and debris during grinding operations.
