15F804 - Walter 3-Inch Mounted Flap Wheel 40 Grit

Industrial-Grade Finishing and Deburring

The Walter 15F804 Flap Wheel is a precision-engineered abrasive tool designed for demanding industrial environments. Measuring 3 inches in diameter with a 1-1/2 inch width, this wheel is constructed from premium industrial-grade abrasive cloth that ensures consistent wear and longevity. The 40 grit composition makes it an aggressive yet controlled option for stock removal, shaping, and heavy deburring tasks across a variety of metallurgies.

One of the defining characteristics of this Walter abrasive product is its exceptional balance. The flaps are securely bonded to the core, ensuring that the wheel spins true even at high rotational speeds (up to 20,000 RPM). This balance is critical for achieving a uniform surface finish, as it eliminates the chatter and vibration often associated with lower-quality flap wheels. The result is a smooth, refined satin finish that requires less rework and secondary processing.

Engineered for versatility, the 15F804 is compatible with steel, stainless steel, and aluminum workpieces. Its mounted design, typically featuring a standard 1/4" shaft, allows for easy integration with die grinders and rotary tools, making it indispensable for accessing internal diameters, contours, and irregular surfaces that rigid grinding wheels cannot reach. Whether used for blending weld seams or general surface conditioning, this flap wheel delivers reliable, professional-grade performance.

Operators will appreciate the linear finishing action provided by the flap configuration. As the wheel wears, new abrasive grain is constantly exposed, maintaining the cut rate and finish quality throughout the life of the product. This self-sharpening effect, combined with the durable backing cloth, maximizes the cost-efficiency of the abrasive by extending intervals between replacements.
