CGW 41004 3" X 1" X 1/4"-20 Threaded Shank 40-Grit Straight Aluminum Oxide Flap Wheel

The CGW 41004 flap wheel is a 3-inch diameter, 1-inch wide, 1/4-20 threaded shank aluminum oxide flap wheel designed for versatile material removal and finishing tasks in tight spaces. Its construction features a firm aluminum oxide-coated abrasive material with flaps arranged around the shaft in a fan-like pattern, which supports a consistent cutting action, extended life, and steady performance across use. This configuration helps maintain an even surface as you work through contours and corners, making it suitable for a range of applications where reach and control are important.

The wheel is rated for use on common metals and other materials, including steel, stainless steel, iron, brass, aluminum, as well as plastic, fiberglass, wood, and glass. The 40-grit specification provides a balance between material removal and surface finish, enabling effective deburring, blending, and light shaping on varied substrates. The 20,000 RPM rating conveys the high-speed capability appropriate for small-diameter flap wheels and requires compatible tooling to ensure safe operation. Packaging is listed as each with box quantities of 10, which may influence procurement planning and inventory handling.

When selecting this accessory, verify that your tool accepts a 1/4-20 threaded shank and that the workpiece geometry allows access for a 3-inch diameter wheel. The 1-inch wheel width supports generous contact area for controlled material removal, while the aluminum oxide abrasive is a common, general-purpose option for multi-material finishing tasks. Routine inspection of the flaps for wear and replacing the wheel when coverage declines will help maintain consistent performance between uses.

Features:

• Firm, quality Aluminum Oxide coated abrasive material. The flaps, arranged like a fan around the shaft of the tool, provide for consistent cutting action, maximum performance and long life.
• Use on steel, stainless steel, iron, brass, aluminum, plastic, fiberglass, wood and glass. Excellent for working in small, difficult to reach places.
