The CGW 42712 7" x 5/8"-11 Type 27 Zirconia flap disc is designed for aggressive material removal on ferrous metals. This flap disc combines premium zirconia alumina grain with a durable poly/cotton backing to balance stock removal with a finishing tendency. Zirconia concentration is chosen to provide efficient material removal while maintaining a workable edge geometry, making it suitable for heavy-duty grinding tasks commonly encountered in fabrication and maintenance environments.
Construction features include a Type 27 profile that delivers a flatter contact angle for more consistent grinding on curved and flat surfaces, and a 7" diameter with a 5/8"-11 arbor to fit standard high-speed grinders used in metalworking. The discs are sized and packaged for easy inventory and replacement, with a grit rating of 40 and an RPM rating of 8600 to support robust workflow demands. The active grinding aid incorporated into the formulation aims to reduce heat buildup during use, which can help minimize glazing and prolong disc life under heavy cuts when used with light to moderate pressure.
Ideal use scenarios include aggressive stock removal on steel and similar substrates where high material removal rates are valued. Operators should resist applying excessive pressure to avoid glazing and to maximize disc efficiency. Compatibility is defined by the 7" diameter and 5/8"-11 threaded arbor common to many high-speed grinders; ensure the grinder's RPM rating aligns with the disc’s 8600 RPM limit. Each package contains ten discs, enabling scalable replenishment for shops with regular metalworking throughput.
