CGW 42512 5" X 5/8"-11 Type 27 40-Grit Z3 Zirconia Flap Disc

The CGW 42512 5" x 5/8"-11 Type 27 40-Grit Zirconia Flap Disc is designed for aggressive material removal on steel surfaces. It features premium zirconia alumina grain bonded to a durable poly/cotton backing, combining robust stock removal with a reasonable finish. The zirconia concentration and the Type 27 wheel shape are optimized for grinding at angles that maximize material removal while maintaining a productive work rate. An active grinding aid is included to help promote cooler cutting action under light pressure, which can help manage heat buildup during extended grinding sessions.

This flap disc is specified for use at up to 12,200 RPM and accepts a 5/8-11 threaded arbor, making it compatible with common angle grinders in industrial and workshop settings. The combination of grit size and abrasive material targets efficient removal of material from steel, supporting aggressive use and heavy-duty applications. The disc is packaged in a standard quantity suitable for shop inventory and repeat purchases, with the 5" diameter and Type 27 configuration aligning with typical surface grinding operations where a flatter contact surface is desired.

When selecting this disc, ensure compatibility with your grinder’s arbor and verify the intended surface finish requirements, as Type 27 discs are shaped for contour grinding on flat and mildly curved surfaces. Regular inspection of the flap segments for wear and orderly replacement scheduling will help maintain consistent performance across cycles.
