CGW 42362 4-1/2" x 7/8" Type 29 40-Grit XL Zirconia Flap Disc is designed for aggressive material removal on steel surfaces. This flap disc combines premium zirconia alumina grain with a poly/cotton backing to balance durability and finish quality while maintaining effective stock removal. The zirconia abrasive concentration is intended to sustain high material removal rates and heat resistance, supporting longer usability between changes when working on demanding applications.
The Type 29 profile provides an inclined operating surface that helps maintain an aggressive cut while reducing gouging on flat workpieces. The XL format offers extended disc life by distributing wear across more abrasive flaps, which can translate to fewer disc changes in heavy-duty tasks. An active grinding aid is included to aid cool cutting under light pressure, contributing to improved control and reduced heat buildup during use on steel components.
This flap disc is specified for use with standard 4-1/2" right-angle grinders requiring a 7/8" arbor. It is packaged with multiple discs per box for efficiency in shop environments, and the 40-grit rating indicates a coarse surface intended for fast material removal rather than fine finishing. When selecting this disc, confirm compatibility with your grinding equipment, ensure correct application technique to maximize the benefits of the abrasive mix, and observe appropriate personal protective equipment and workpiece mounting practices to avoid gouging or disc separation during operation.
