The CGW 39474 flap disc delivers a robust finishing and material-removal solution for metalworking and related applications. Designed with a premium aluminum oxide grain on a polyester backing, this 4-1/2 inch, 5/8-11 threaded arbor Type 29 flap disc is suited for aggressive material removal and blend work on ferrous and non-ferrous metals, as well as certain plastics and wood. The 60-grit configuration provides a balance between stock removal and surface finish, making it a practical choice for deburring, edge chamfering, and finishing operations where a flatter contact surface is needed for contour work.
The Type 29 profile exposes the grinding surface at a favorable angle for shaping and de-burring on flat or contoured surfaces, while the XL construction denotes an extended length of abrasive flaps to sustain performance under higher workloads. Aluminum oxide, a versatile and economical abrasive, is well-suited for a range of metals and other substrates, helping to achieve consistent results across multiple passes. The disc runs at up to 13,300 RPM, which supports efficient material removal with controlled heat generation when used with appropriate guards and safety practices.
Typical applications include deburring and finishing of metal edges, weld seams, and profiles, where a stable disc with uniform wear is beneficial. When selecting this disc, ensure compatibility with a 4-1/2 inch tool using a 5/8-11 mounting thread and observe proper speed ratings and guard clearances. Packaged individually with a box quantity of 10, this disc is suitable for shop inventory where replacement discs are needed to maintain continuous workflow.
