CGW 42332 4-1/2" X 5/8"-11 Type 29 40-Grit Z3 Zirconia Flap Disc

The CGW 42332 is a 4-1/2 inch diameter, 5/8-11 thread-on Type 29 flap disc designed for aggressive material removal on steel surfaces. Featuring premium Zirconia Alumina grain on a durable poly/cotton backing, this disc combines resilience with a fine surface finish. The Zirconia concentration provides high stock removal, while the active grinding aid helps maintain cooler cutting temperatures under light pressure, contributing to extended wheel life and steadier performance during heavy-duty grinding tasks.

Key construction details include a Type 29 profile for versatile flattening and contour grinding, and a 40-grit size that balances rapid material removal with a relatively smooth finish. The disc is rated for up to 13,300 RPM, suitable for high-speed grinding applications common in metal fabrication, maintenance, and repair environments. Each package contains 10 units, making it practical for bulk use on job sites or shop floors. This flap disc should be used with compatible angle grinders that accept 5/8-11 threaded accessories and appropriate safety equipment to manage heat and debris during operation.

When selecting this disc, consider the project demands: its aggressive grain and profile are intended for heavy-duty steel work where fast material removal is prioritized. The poly/cotton backing supports extended disc life and helps sustain consistent contact with the workpiece, while the zirconia composition contributes to longevity in demanding grinding conditions. Ensure proper mounting and torque specifications for your grinder, and follow standard PPE guidelines to protect against sparks, flying particles, and dust.
