CGW 39464 4-1/2" X 7/8" Type 29 60-Grit XL A3 Aluminum Oxide Flap Disc

The CGW 39464 flap disc is designed for rapid material removal and finishing on a variety of substrates. With a 4-1/2 inch diameter and a 7/8 inch arbor, this Type 29, 60-grit disc uses premium aluminum oxide grain bonded to a polyester backing to deliver efficient grinding action on ferrous and non-ferrous metals, as well as plastics and wood. The XL formulation indicates an extended life construction intended for higher productivity applications, while the A3 designation reflects a versatile shape suitable for contour grinding and material removal in tight or angled spaces.

The combination of aluminum oxide grain and a sturdy backing supports consistent performance under demanding use. This disc is compatible with standard angle grinders that accept 4-1/2 inch flap discs and is designed for high RPM operation, rated up to 13,300 RPM, which aligns with common performance expectations in metalworking and fabrication environments. The 60-grit size provides a balance between material removal rate and surface finish, making it suitable for lighter deburring, edge shaping, and rust or paint removal on a variety of substrates.

Practical considerations include using the disc with compatible grinders and ensuring correct mounting to avoid wobble or vibration. Each package contains multiple discs, with a box quantity of 10, supporting bulk purchases for shop floors or job sites. Because performance is influenced by workpiece material and tool speed, verify that your application is appropriate for aluminum oxide grain on the chosen substrate to achieve the intended finish and efficiency.
