CGW 70121 4-1/2" X 5/8"-11 Type 29 Brown Coarse Non-Woven Surface Conditioning Flap Discs

CGW 70121 4-1/2" x 5/8"-11 Type 29 Brown Coarse Non-Woven Surface Conditioning Flap Discs are designed for aggressive surface conditioning tasks on steel and stainless steel. These brown coarse discs use non-woven conditioning material to blend, deburr, and clean surfaces, helping to prepare a substrate for finishing or coating. The product family includes three grit options within the same overall disc size and configuration: 120 grit brown coarse discs for heavy material removal, 180 grit maroon discs for intermediate finishing, and 320 grit blue discs for very fine finishing. This makes the set suitable for progressive smoothing or spot blending depending on the job requirements.

Constructed to operate at 3,000 RPM, the discs are intended for applications that require efficient material removal while maintaining control over the workpiece surface. The Type 29 flap design provides a more aggressive edge profile, which can enhance contact with contoured surfaces and edge work compared with flat surface conditioning products. The 4-1/2" diameter with a 5/8"-11 arbor ensures compatibility with common angle grinders and standard mounting hardware used in metal fabrication and maintenance tasks.

The discs are specified as non-woven conditioning media, and the available grit options enable users to select an appropriate level of aggressiveness for deburring, blending, or cleaning tasks on steel and stainless steel substrates. When selecting and using these discs, ensure the backing surface and grinder are suitable for 3,000 RPM operation and that the arbor size matches the tool’s spindle. Each package contains discs sized for standard tool compatibility, with a typical box quantity of 10 units per set, designed to integrate into routine maintenance and fabrication workflows.
