Cgw 42402 Ceramic Flap Disc 4-1/2x7/8 in 40 Grit 10 Pack

Product Description

The CGW 42402 is a C3 compact ceramic flap disc designed for aggressive material removal and long service life on metal fabrication applications. Measuring 4-1/2 inches in diameter with a 7/8-inch arbor hole, this disc runs on standard angle grinders used daily in welding shops, fabrication facilities, and job-site metalwork. The 40-grit ceramic abrasive cuts fast on hard metals and maintains a consistent cut rate longer than conventional aluminum oxide or zirconia flap discs. Each box contains 10 discs, making it a practical stocking unit for professional users who run through abrasives at volume.

This flap disc suits grinding, blending, and stock removal on carbon steel, stainless steel, and hard alloys. The 4-1/2-inch diameter is the most common angle grinder wheel size in trade use, fitting a wide range of 4-1/2-inch and 5-inch grinders with a standard 7/8-inch arbor. It is well suited for weld seam removal, surface preparation before coating, and edge deburring in both residential fabrication and light industrial settings. The C3 ceramic grain construction is manufactured in the USA.

Installation Notes

Flap discs are installed and replaced by metalworkers, welders, and fabricators using standard angle grinders. Before changing a disc, disconnect the grinder from its power source and allow any rotating disc to come to a complete stop. Inspect the backing plate and flange for damage before mounting a new disc, and confirm the grinder RPM rating meets or exceeds the disc RPM rating. Always wear appropriate PPE including a face shield when operating angle grinders.
