The CGW 43104 flap disc is a 4-1/2 inch diameter, 7/8 inch arbor Type 29 flap disc designed for aluminum and other non-ferrous metals. Its 60-grit configuration uses aluminum oxide abrasive with a calcium stearate treatment. This specialized coating helps keep the disc cooler during use and reduces loading from soft materials, which can improve consistency and reduce glazing when working on aluminum surfaces.
The disc features a unique construction intended to optimize performance on non-ferrous metals. The combination of aluminum oxide grain and the calcium stearate finish provides continued cutting action while mitigating heat buildup and clogging, making it suitable for applications where overheating and material buildup may be a concern. The product is sized for standard 4-1/2 inch grinding systems with a 7/8 inch arbor, and it is specified to operate at up to 13,300 RPM, aligning with typical high-speed flap disc usage patterns.
This item is sold in box quantities of 10 and is intended for use on aluminum and similar non-ferrous materials. When selecting discs and setup, confirm compatibility with your grinder’s arbor size and maximum RPM, and follow safe grinding practices to maintain disc integrity and workpiece finish. Proper mounting, speed control, and grinding pressure help maximize the disc’s cooling and anti-loading benefits, especially on aluminum tasks where heat management is important.
