CGW 49626 4-1/2" X 7/8" Type 29 60-Grit Brown Aluminum Oxide Red Fiber Backing Semi-Flex Disc

The CGW 49626 is a semi-flex resin-bonded abrasive disc designed for 4-1/2-inch angle grinders, featuring a Type 29 profile with a 7/8-inch arbor/shank and 60-grit aluminum oxide grain. This configuration supports aggressive material removal while maintaining control on curved or contoured surfaces, making it suitable for both metalworking and certain non-ferrous applications. The red fiber backing provides a balance of durability and conformity for deburring, grinding, and finishing tasks on a variety of substrates.

Construction details identify aluminum oxide as the primary grain, chosen for its versatility across common metals such as cold-rolled steel, stainless steel, bronze, aluminum, and iron. The disc is specified at a 4-1/2-inch diameter with a 7/8-inch arbor, Type 29 configuration, and is rated for use up to the indicated RPM, ensuring appropriate speed matching for compatible grinders. The product is packaged as individual discs, with a box quantity of 25, which can influence stocking and project planning in maintenance and fabrication settings.

Practical use considerations include selecting 60-grit aluminum oxide for material removal and surface preparation where a balance between aggressiveness and surface finish is desired. While the data notes the materials and abrasive type, users should verify compatible equipment RPM and mounting to ensure safe operation. This disc is appropriate for tasks such as deburring, smoothing rough edges, and light finishing on ferrous metals, non-ferrous materials, and some coated surfaces, depending on the workpiece and finish requirements. When replacing worn discs, confirm the Type 29 profile and center arbor size to maintain proper contact and grinding efficiency.
