CGW 42534 5" X 5/8"-11 Type 29 60-Grit Z3 Zirconia Flap Disc

The CGW 42534 5" X 5/8"-11 Type 29 60-Grit Z3 Zirconia Flap Disc is designed for efficient metal grinding and material removal. This flap disc combines premium zirconia alumina grain with a poly/cotton backing to deliver a durable abrasive surface and a fine finish. The zirconia concentration supports higher stock removal rates compared with standard aluminia blends, making it well-suited for aggressive grinding on steel applications. An active grinding aid is included to help maintain cooler cutting under light pressure, which can extend disc life and reduce heat buildup during extended use.

Construction details focus on performance and versatility: the Type 29 profile provides an angled grinding surface that can reach into corners and awkward profiles, while the 5" diameter and 5/8-11 inch arbor ensure compatibility with common portable grinders used in maintenance and fabrication settings. The 60-grit rating indicates a balance between material removal and surface finish, suitable for shaping, deburring, and blending operations on ferrous metals. This disc is intended for heavy-duty applications where faster stock removal is a priority, and its design supports continued use with proper technique and appropriate workholding.

Practical considerations include using moderate pressure and maintaining appropriate wheel speed to maximize the benefits of the zirconia blend. The disc is packaged as individual units within a box containing multiple pieces, facilitating inventory management for maintenance and facility teams. When selecting tooling, verify grinder compatibility with a 5/8-11 arbor and ensure the operating RPM rating (up to 12,200 RPM) aligns with the tool being used to avoid over-speed conditions. The product supports standard maintenance workflows that require robust metal-removal abrasives for fabricating, deburring, and finishing tasks.
