The CGW 42344 4-1/2" x 7/8" Type 27 60-Grit XL Zirconia Flap Disc is engineered for aggressive material removal on steel and related metals. Built with premium zirconia alumina grain bonded to a durable poly/cotton backing, this disc combines robust stock removal with a smoother finish, leveraging zirconia’s high grain hardness and heat tolerance to maintain cutting efficiency under heavy-duty use. The XL configuration expands abrasive surface area, supporting faster material removal while helping to extend cycle life compared with standard flap discs.
Key features include a zirconia grain formulation optimized for durability and consistent cutting action, plus an active grinding aid designed to dissipate heat and reduce clumping during use. This combination enables cooler cutting with light pressure, which can help lessen workpiece heat-affected zones and improve overall control in grinding operations. The Type 27 profile is shaped for grinding angles and contour work, making it suitable for curved surfaces and edge blending while maintaining efficient stock removal.
Use this flap disc on compatible 4-1/2 inch right-angle grinders for aggressive deburring, shaping, and surface finishing on steel and similar metals. The product is specified with a 7/8 inch arbor/shank size and a maximum operating speed of 13,300 RPM, which informs compatible tool selection and safe operation. Each package contains ten discs, aligning with continuous production or maintenance workflows where multiple discs are needed for extended jobs. Maintain appropriate PPE and follow standard wheel and disc safety practices during grinding operations.
