The CGW 43111 flap disc is a 4-1/2 inch diameter, 5/8-11 arbor, Type 29 configuration designed for aluminum and other non-ferrous materials. It features 36 grit aluminum oxide abrasive with a calcium stearate coating intended to keep heat generation down and reduce loading when working with soft metals. This coating helps dissipate heat and minimizes clogging, which can help maintain grinding efficiency and finish consistency on non-ferrous workpieces.
The disc’s construction aligns with a typical Type 29 profile, providing a flatter working face for aggressive stock removal while still delivering corrective grinding action. The calcium stearate treatment is specifically noted as a feature to help manage temperature and material buildup, which can be advantageous when finishing aluminum that is prone to loading with softer materials. The disc is positioned for use on standard 4-1/2" angle grinders configured with a 5/8"-11 mounting thread, and its 36-grit rating indicates a balance between material removal rate and surface finish quality for aluminum and similar metals.
When planning use, consider that this disc is rated for up to 13,300 RPM, which should be matched to the tool’s maximum operating speed to avoid overspeed conditions. Each package contains ten discs, suitable for batch replacement in maintenance environments. For best results, verify compatibility with your grinder and ensure proper clamping to prevent runout or imbalance during operation. The design emphasizes non-ferrous applications and may deliver improved performance where aluminum loading and heat buildup are concerns, helping maintain process efficiency during material removal and finishing tasks.
