CGW 31014 4-1/2" X 7/8" Type 27 60-Grit ZS Zirconia Flap Disc

The CGW 31014 flap disc is a 4-1/2 inch diameter grinding accessory designed for metal surface finishing and material removal. It features a Type 27 recessed design and a 7/8 inch arbor/shank, optimized for grinding and blending on contoured edges and curved surfaces. The disc uses a premium blend of zirconia and aluminum oxide grains with a grinding aid, which provides efficient material removal while helping to manage heat generation during use. This construction is particularly noted for its effectiveness on stainless steel applications and in heat-sensitive operations, where controlling temperature can help preserve part dimensions and finish quality.

The zirconia-alumina blend in the 60-grit size enables robust cutting action while maintaining a relatively cool operating temperature compared with finer grits, contributing to smoother finishes on stainless steels and similar alloys. The 60-grit specification indicates a balance between material removal rate and the ability to generate a finer surface, making it suitable for deburring, blending, and light stock removal in fabrication and maintenance tasks. Operating at up to 13,300 RPM, users should select compatible power tools and ensure proper guard and PPE use to manage sparks, dust, and heat. The disc is packaged as an individual unit within a box quantity of 10, facilitating stocking for service and maintenance environments.

This product is compatible with standard 4-1/2 inch angle grinders and non-caline arbor configurations that support a 7/8 inch shank. Maintenance considerations include inspecting the flap disc for wear and disc integrity before each use and replacing when grit exposure becomes uneven or backing material shows signs of damage. For best results, use as part of a controlled grinding process on metal surfaces, avoiding excessive pressure that could cause overheating or breakage.
