CGW 43853 4-1/2" X 5/8"-11 Type 29 80-Grit PSG Ceramic Extreme II Flap Disc

The CGW 43853 4-1/2" x 5/8"-11 Type 29 80-Grit PSG Ceramic Extreme II Flap Disc is designed for high-efficiency material removal on angle grinders. This flap disc features Precision Shaped Grain (PSG) Ceramic, which stays sharper longer for faster cutting and cooler operation, contributing to sustained productivity in tough grinding tasks. The 4-1/2 inch diameter with a 5/8-11 arbor makes it compatible with common right-angle grinders used in industrial maintenance, fabrication, and workshop settings. The Type 29 profile provides a depressed center that helps maintain aggressive grinding angles on curved or irregular surfaces, supporting smoother material removal with controlled grind lines.

PSG Ceramic grains are formulated to deliver longer lifespan and higher performance than conventional abrasive chemistries, translating to fewer disc changes during lengthy repair, deburring, or stock-removal work. This Extreme II variant emphasizes durability and versatility across a range of metals and finishes, allowing operators to work efficiently without sacrificing control. The disc is intended for use with appropriate guard and PPE, and operators should follow standard grinding best practices to manage heat generation and surface finish.

Package details indicate the disc is sold per piece with boxed quantities of 10, aiding inventory planning and stocking. When selecting this disc, ensure the grinder’s RPM capability aligns with the rated 13,300 RPM to maintain performance and safety. The 4.5" diameter and 0.625"-inch arbor size are typical for compact to mid-range grinders, making this option suitable for smaller fabrication tasks, deburring, edge chamfering, and finishing operations where aggressive material removal is required without excessive heat buildup.
