CGW 70123 4-1/2" X 5/8"-11 Type 29 Maroon Medium Non-Woven Surface Conditioning Flap Discs

The CGW 70123 flap discs are a 4-1/2" diameter, 5/8-11 threaded arbor Type 29 textured maroon medium non-woven surface conditioning discs designed for metal prep on steel and stainless steel. These discs use a non-woven conditioning material arranged in a three-grit system to support blending, deburring, and cleaning tasks in a single wheel configuration, helping users address common metal finishing needs with varied aggressiveness.

Three distinct grits are represented within the same product family: brown (120 grit) for coarser material removal, maroon (180 grit) for medium finishing, and blue (320 grit) for very fine finishing. This arrangement provides versatility for surface conditioning workflows without swapping discs, while the Type 29 wheel profile helps maintain an aggressive cut on irregular surfaces and edges. The discs are intended to operate at approximately 3,000 RPM to balance material removal with control for typical shop and fabrication environments.

Practical use considerations include selecting the appropriate grit based on the target finish and material condition prior to final polishing or coating. Each disc is manufactured in a 4-1/2" size with a 5/8-11 arbor to fit compatible right-angle grinders commonly used in metal fabrication, automotive, and maintenance tasks. The package quantities indicate individual discs with a box quantity of 10 parts, enabling easy stocking and replacement in busy maintenance settings. When using these surface conditioning discs, ensure proper PPE and follow tool and grinder manufacturer guidelines for mounting and RPM limits.
