CGW 41722 4-1/2" x 7/8" Type 29 40-Grit Zirconia Flap Disc is designed for metalworking applications, specifically on steel surfaces. This flap disc combines zirconia grain with a poly/cotton backing to deliver a durable cutting and finishing action while maintaining a consistent finish on the workpiece. The Type 29 configuration provides a depressed center profile suitable for grinding at more aggressive angles, helping to remove material efficiently in roughing and blending tasks.
The zirconia abrasive grain is known for self-sharpening properties and high heat resistance, which can contribute to sustained performance on steel parts. The poly/cotton backing enhances the disc’s durability and finish integrity, supporting longer life under typical shop conditions. The 4-1/2" diameter with a 7/8" arbor size matches common angle grinder tooling, and the disc is rated for up to 13,300 RPM, which informs appropriate tool selection and guarding requirements in standard metal fabrication workflows. Package details indicate individual discs, with a box quantity of 10, aiding stocking and procurement planning.
When selecting this disc, ensure compatibility with your grinder’s arbor size and guard clearance, and follow manufacturer safety recommendations for flap discs. This product is intended for steel applications and should be used in appropriate grinding, deburring, and finishing operations where a Type 29 depressed-center flap disc is indicated.
