CGW 39202 4" X 5/8" Type 27 40-Grit A3 Aluminum Oxide Flap Disc

The CGW 39202 4" x 5/8" Type 27 flap disc is designed for versatile abrasive finishing on ferrous and non-ferrous metals, as well as plastics and wood. It features premium aluminum oxide grain bonded to a durable polyester backing, delivering a balance of cut-rate and longevity suitable for deburring, blending, and surface finishing tasks on a range of materials commonly encountered in facility maintenance and fabrication environments. The Type 27 construction provides a right-angle grinding profile that can produce curved or contoured surfaces, while the 40-grit grade offers a coarse finish that facilitates material removal without excessive heat buildup when used at appropriate speeds.

The disc is sized for standard 4-inch tooling with a 5/8-11 arbor, enabling compatibility with common grinders and sanders used in shop floors and maintenance bays. It is rated for up to 15,300 RPM to accommodate high-speed operation typical of power tools in industrial settings. Each disc is packaged individually or in box quantities of 10, supporting either single-use replacement or bulk stocking for maintenance inventories. When selecting this flap disc, ensure proper wheel mounting and guard coverage, and match grit and disc type to your specific material and finish goal to avoid gouging or uneven wear.

This CGW product is identified by CGW39202, aligning with standard cataloging for reuse and replacement in maintenance workflows. The combination of aluminum oxide grain, Type 27 configuration, and 40-grit sizing offers a practical option for efficient material removal and surface preparation across metals and compatible substrates, with attention to proper speed ratings and arbor fit to maintain spindle integrity and tool life.
