CGW 39462 4-1/2" X 7/8" Type 29 40-Grit XL A3 Aluminum Oxide Flap Disc

CGW 39462 is a 4-1/2 inch diameter, 7/8 inch arbor Type 29 flap disc designed for versatile material removal and finishing tasks. This disc uses premium aluminum oxide grain bonded to a polyester backing, which provides good balance between aggressive cutting action and long life on a variety of substrates. The Type 29 profile is wheel-like with a conical face that facilitates access to angled surfaces and concave contours, helping create a smooth finish on both flat and contoured workpieces. The XL designation indicates an extra-long flap arrangement, contributing to a broader contact surface for efficient material removal. With a maximum operating speed of 13300 RPM, the disc is intended for high-speed grinders and compatible power tools within standard workshop settings.

Constructed to handle ferrous and nonferrous metals as well as plastics and wood, this flap disc offers flexibility across metal fabrication, maintenance, and light fabrication tasks. The 40-grit rating signals a relatively aggressive grain size suitable for substantial material removal and deburring, though care should be taken to maintain even pressure and use appropriate dressing to achieve the desired finish. Practically, operators should select this disc when shaping edges, smoothing welds, or removing rust and scale from metal surfaces. Proper use requires secure mounting on a compatible grinder and adherence to tool speed ratings, personal protective equipment, and manufacturer guidelines.

Package information indicates each disc is sold individually with a box quantity of 10, supporting bulk stocking without mixing different sizes. When selecting replacement discs, confirm the 4-1/2" diameter, 7/8" arbor size, Type 29 configuration, and 40-grit Aluminum Oxide on polyester backing to ensure proper fit and performance on your grinder setup.
