CGW 39990 2" X 1" X 1/4"-20 Threaded Shank 80-Grit Straight Aluminum Oxide Flap Wheel

The CGW 39990 is a 2 inch by 1 inch by 1/4 inch-20 threaded shank flap wheel designed for precise material removal and finishing in tight spaces. This straight-flap wheel uses aluminum oxide abrasives arranged around the shaft to deliver a consistent cutting action and extended wheel life, making it suitable for a variety of metals and non-metallic materials. The 80-grit grade provides a balance between material removal rate and surface finish, which is helpful for deburring, blending, and light finishing tasks on small components and hard-to-reach areas.

Construction features a firm aluminum oxide coated abrasive, chosen for its durability and versatile performance across steel, stainless steel, iron, brass, aluminum, as well as plastics, fiberglass, wood, and glass. The shank enables direct mounting on compatible rotary tools or drill-powered devices, accommodating use in restricted cavities where larger wheels cannot reach. Proper selection of grit and wheel geometry supports controlled material removal while helping minimize heat buildup and gouging in delicate applications.

When planning use, verify that your tool accepts a 1/4-20 threaded shank and that the RPM rating aligns with the tool’s capabilities. Each wheel is packaged individually with a common 10-per-box configuration, facilitating easy inventory management for shops that regularly service small parts or fit-out jobs requiring frequent, precise touch-ups. Regular inspection for wear and proper mounting can help maintain consistent performance and prolong wheel life.
