CGW 42335 4-1/2" X 5/8"-11 Type 29 80-Grit Z3 Zirconia Flap Disc

CGW 42335 4-1/2" x 5/8"-11 Type 29 80-Grit Z3 Zirconia Flap Disc is designed for aggressive material removal on steel surfaces. This flap disc features a premium zirconia alumina grain bonded to a durable poly/cotton backing, combining robust stock removal with a smoother finish. The zirconia concentration aids cutting efficiency, while the backing material helps maintain disc integrity under heavy use. The incorporation of an active grinding aid supports cooler cutting under light to moderate pressure, which can help manage heat during extended grinding sessions.

Constructed as a Type 29 disc with a 4-1/2" diameter and a 5/8"-11 arbor, this disc is suitable for right-angle grinders commonly used in metal fabrication and maintenance tasks. The 80-grit sizing provides a balance between material removal and surface finish, making it appropriate for aggressive shaping, deburring, and stock-removal workflows on steel components. The product is packaged as individual discs with a box quantity of 10, facilitating ready-to-use stock for shops that perform regular metal grinding tasks.

When selecting this flap disc, ensure your grinder supports a 5/8"-11 arbor and that the workpiece is clamped and secured to prevent kickback. Regular inspection for wear and disc integrity is advised to maintain consistent performance. The combination of zirconia grain and active cooling features may influence heat generation and wear patterns relative to other grain types; users should adjust pressure and feed rate accordingly to optimize material removal while preserving part tolerances.
