CGW 41764 4-1/2" X 7/8" Type 29 60-Grit XL ZPC Zirconia Flap Disc

The CGW 41764 4-1/2 inch by 7/8 inch Type 29 zirconia flap disc is designed for reinforced material removal and finishing on ferrous metals. This disc features zirconia grain bonded to a poly/cotton backing, which contributes both durability and finish strength during high-pressure grinding tasks. The Type 29 profile provides an angled grinding surface that can effectively reach contours and uneven surfaces, making it a practical choice for shaping, deburring, and finishing welds on steel components. The 60-grit designation targets faster material removal with a controlled surface finish, while the XL construction suggests an extended life compared with standard-density offerings. Operation at a maximum RPM around 13,300 supports efficient workflow in heavy-duty metalworking environments.

In terms of construction, zirconia grain is known for its self-sharpening properties and durability under grinding pressure, and the poly/cotton backing adds resilience to the flap structure. This combination helps maintain consistent cutting performance while resisting tearing and heat buildup in demanding applications. The 4-1/2 inch diameter and 7/8 inch arbor/shank size align with common grinding tools used in fabrication, metal fabrication shops, and maintenance operations that require aggressive material removal on steel. As with all flap discs, expected results depend on proper selection, mounting, and technique, including applying the disc to the workpiece at an appropriate angle and using compatible grinders.

Packaging details indicate the product is sold as individual discs, with a box quantity of 10, suitable for stocking and replenishment in maintenance depots and workshops. Maintain standard safety practices, verify grinder compatibility and speed ratings, and inspect the disc for damage before use to ensure consistent performance.
