CGW 39444 4-1/2" X 7/8" Type 27 60-Grit XL A3 Aluminum Oxide Flap Disc

CGW 39444 4-1/2" x 7/8" Type 27 60-Grit XL A3 Aluminum Oxide Flap Disc is designed for material removal and shaping on a variety of substrates. The disc features premium aluminum oxide grain bonded to a durable polyester backing, delivering consistent cutting action and extended life for metalworking and related applications. The Type 27 profile provides an angled configuration suitable for flat surfaces and edge work, enabling efficient grinding and smoothing on larger areas as well as curved contours.

This flap disc uses XL construction for higher material removal capability and longer service life relative to standard discs. The A3 designation indicates versatility across ferrous and non-ferrous metals, as well as plastics and wood, making it a flexible option for multi-material projects where occasional material blending or deburring is required. The 60-grit size targets mid-range material removal with a balance of aggressiveness and surface finish, while the 4-1/2" diameter and 7/8" arbor/shank size ensure compatibility with common angle grinders and accessory kits. The maximum operating speed is indicated at 13,300 RPM, which should be observed to maintain performance and safety.

For practical use, ensure the disc is properly mounted and aligned with the grinder arbor to prevent vibration and heat buildup. The packaging quantity is 10 discs per box, offering ample supply for project runs or shop-wide usage without frequent reorders. This disc is suitable for metal fabrication, maintenance, and general shop tasks where deburring, edge rounding, or blending of welded joints is needed, while also accommodating plastics and wood in mixed-material workflows where appropriate.
