The CGW 39920 is an aluminum oxide flap wheel designed for grinding, blending, and finishing on metal surfaces. It measures 1.5 inches in diameter by 1 inch wide with a 0.25 inch shank, making it compatible with standard die grinders and rotary tools. The 40-grit aluminum oxide abrasive delivers aggressive stock removal on steel, cast iron, and other ferrous metals. The firm backing maintains wheel integrity under consistent pressure. Each box contains 10 wheels, suited for shop use or field applications where multiple consumables are needed per job. Metalworkers, fabricators, and maintenance technicians are the primary users of this type of abrasive tooling.
This flap wheel is well suited for weld blending, surface preparation, and deburring in fabrication shops, manufacturing facilities, and maintenance environments. The 0.25 inch shank fits standard die grinder collets, making it a practical consumable for work in tight spaces or on contoured surfaces where flat discs cannot reach. The 40-grit cut is appropriate for initial material removal before stepping to finer grits for finish work.
Designed for use with standard die grinders and rotary tools accepting a 0.25 inch shank. Suitable for grinding, blending, and finishing on steel, cast iron, and similar ferrous metal workpieces.
Flap wheels of this type are installed by inserting the shank into a die grinder collet and tightening securely before operation. Always verify the tool RPM rating meets or exceeds the wheel's rated speed before use. Wear appropriate PPE including eye protection and gloves when operating abrasive tooling. Inspect each wheel for damage before mounting and do not use wheels that show cracking or missing flaps.
