The CGW 35831 is a 4-1/2 inch by 7/8 inch Type 29 semi-flex grinding disc designed for versatile surface material work. This 24-grit disc pairs brown aluminum oxide grains with a red fiber backing to deliver efficient material removal on a range of substrates, including metals and non-ferrous materials. The Type 29 shape provides an angled contact for aggressive yet controlled grinding and finishing, making it suitable for contour work and edge work where a flatter disc would be less effective.
Construction details indicate aluminum oxide grains favored for metalworking tasks such as refining rough castings and deburring, while the semi-flex backing supports conforming to slight contours and flat surfaces alike. The combination aims to balance material removal with a smoother finish on challenging surfaces, helping to reduce cycles on longer grinding projects.
Typical applications include deburring and finishing on cold-rolled steel, stainless steel, bronze, and aluminum, as well as removal of coatings, mastics, and other non-ferrous contaminants from fiberglass, quartz, terrazzo, and similar substrates. Operators should consider the disc’s 4-1/2
