CGW 42871 4-1/2" x 7/8" Type 29 40-Grit XL PSG Ceramic Extreme II Flap Disc is designed for high-performance grinding on metal surfaces. The disc uses Precision Shaped Grain (PSG) Ceramic technology, which is engineered to stay sharper longer, delivering cooler operation and faster material removal compared with conventional abrasive grains. This results in improved productivity and durability during extended use. The Type 29 flap arrangement provides a conical profile suitable for aggressive grinding at recessed edges and contours, making it a versatile choice for metal fabrication and maintenance tasks.
The 4-1/2 inch diameter with a 7/8 inch arbor size fits common right-angle grinders and similar tools used in workshop and field settings. With a 40- grit rating, the disc is intended for general purpose grinding, deburring, and surface finishing on ferrous and non-ferrous metals where aggressive material removal is required while maintaining a relatively fine finish for subsequent steps. The XL construction denotes extra-large flap coverage, which can contribute to longer wheel life and consistent performance across the disc surface, particularly important during batch or repetitive tasks.
When selecting this disc, consider the workpiece material and desired finish. The PSG Ceramic composition and Type 29 profile are optimized for metal grinding applications that benefit from higher cut rates and lower heat buildup, potentially reducing warping on heat-sensitive parts. Ensure compatibility with your grinder’s arbor size and mounting configuration, and follow standard safety practices for flap discs, including proper disc inspection and personal protective equipment during operation.
