CGW 43094 4-1/2" X 5/8"-11 Type 27 60-Grit Calcium Stearate Coated Flap Disc For Aluminum

The CGW 43094 flap disc is engineered for healthier, cooler metal finishing on aluminum and other non-ferrous materials. This 4-1/2 inch diameter disc features a 5/8-11 threaded arbor and Type 27 configuration, delivering aggressive material removal with a 60-grit aluminum oxide surface and a calcium stearate coating. The calcium stearate treatment helps keep the disc cooler and reduces loading when working with soft metals, which can improve control and reduce smear during grinding. This combination is designed to balance material removal with smoother operation on non-ferrous substrates.

In practice, the aluminum oxide grains are bonded to ensure consistent wear across the disc while the calcium stearate coating provides lubricity to minimize heat buildup and clogging. The Type 27 profile offers a favorable grinding angle for flat to slightly curved surfaces, making it suitable for cleaning, deburring, and light material shaping on aluminum parts and similar alloys. The disc is sized for standard 4-1/2 inch grinder wheels and installs on a compatible 5/8-11 spindle, with a typical RPM rating around 13,300, aligning with common portable grinder performance ranges.

For purchasing, note the package configuration is a single disc with ten discs per box, which supports routine maintenance or batch replacements in a workshop setting. Proper use includes matching abrasive speed with the tool’s rated RPM and avoiding excessive pressure to prevent loading and heat buildup, especially on aluminum. While the data does not specify additional compatibility or certifications, selecting this disc informs non-ferrous-focused finishing jobs that benefit from cooler operation and reduced loading during grinding tasks.
