CGW 42734 7" X 5/8"-11 Type 29 60-Grit Z3 Zirconia Flap Disc

The CGW 42734 is a 7 inch diameter flap disc designed for heavy-duty metal finishing and aggressive stock removal. Built with zirconia alumina grain on a durable poly/cotton backing, this Type 29 flap disc balances fast material removal with a workable finish on steel surfaces. The zirconia concentration provides high stock removal rates, while the poly/cotton backing adds flexibility and durability to withstand demanding grinding conditions. An active grinding aid is included to promote cooler cutting under light pressure, helping to reduce heat build-up during extended use.

Key construction features include a 60-grit zirconia grain and a 5/8-11 inch arbor, making it compatible with common high-speed angle grinders operating up to approximately 8600 RPM. The Type 29 angle construction supports grinding and blending at a slightly inclined face, which is well-suited for contouring weld seams, deburring, and material finishing on flat and contoured surfaces. This disc is packaged as a single unit with a box quantity of 10, facilitating bulk purchases for shop workflows.

When selecting this disc, consider its aggressive stock-removal performance and the need for proper personal protective equipment. Use with appropriate guards and ensure grinder RPM does not exceed the rated 8600 RPM for the disc to maintain performance and safety. The product is intended for steel applications where fast material removal and a finishing touch are both desired, and it aligns with standard 7 inch, 5/8-11 arbor tooling commonly found in many facility maintenance and metal fabrication settings.
