CGW 70125 4-1/2" X 5/8"-11 Type 29 Blue Very Fine Non-Woven Surface Conditioning Flap Discs

CGW 70125 4-1/2" x 5/8"-11 Type 29 blue very fine non-woven surface conditioning flap discs are designed for surface preparation on steel and stainless steel substrates. These Type 29 flap discs deliver a blend of deburring, cleaning, and finishing through a three-grit system, enabling users to perform material removal and finishing in a single step. The very fine blue discs correspond to 320 grit, providing a fine finish suitable for final cleanup and light blending tasks when paired with the correct metalworking setup.

Constructed as non-woven conditioning discs, they incorporate a matrix that combines abrasive grains with flexible, durable backing to maintain conformability across contoured or irregular surfaces. The 4-1/2" diameter and 5/8"-11 arbor size align with common right-angle grinders, allowing broad compatibility with standard workshop tooling. Operating at approximately 3,000 RPM, these discs are intended to balance material removal rates with surface quality, emphasizing control on delicate finishes.

This product line uses a color-coded disc system to indicate grit: blue for very fine (320 grit), maroon for medium (180 grit), and brown for coarse (120 grit). The packaging is specified as individual discs with a box quantity of 10, which helps manage stocking and replacement cycles in maintenance environments. When selecting these discs, consider the substrate and desired finish; the blue 320 grit is best for light finishing tasks on steel or stainless steel after deburring or blending is initiated with coarser grits.
