15F004 - Walter 1-1/2 Inch x 3/8 Inch 40 Grit Mounted Flap Wheel

Industrial Precision Finishing with Walter Flap Wheels

The Walter 15F004 1-1/2" x 3/8" x 40 Grit Flap Wheel is an essential abrasive tool for industrial MRO and fabrication environments requiring precision and durability. Engineered with the finest industrial-grade abrasive cloth, this wheel is designed to withstand the rigors of heavy-duty shaping, deburring, and blending applications. Its coarse 40 grit rating makes it particularly effective for removing heavy burrs, flash, and parting lines from castings or machined parts without gouging the workpiece.

One of the defining characteristics of Walter's flap wheel line is the meticulous attention to balance. The flaps are securely arranged around a central hub to ensure concentricity. This design minimizes vibration during high-speed rotation, which is critical when working with handheld die grinders. Reduced vibration not only improves operator comfort and safety but also extends the life of the rotary tool bearings and ensures a consistent, chatter-free finish on the metal surface.

This specific model features a compact 1-1/2 inch diameter and a narrow 3/8 inch width, making it the ideal solution for accessing hard-to-reach areas. Whether you are finishing the inside of a pipe, smoothing out a tight radius, or cleaning up complex contours on a mold, this flap wheel conforms to the workpiece to deliver a uniform satin finish. It is fully compatible with a wide range of materials, including carbon steel, stainless steel, and aluminum, making it a versatile addition to any tool crib.

Professionals trust Walter Surface Technologies for abrasives that deliver consistent results time after time. By maintaining a fresh cutting surface as the flaps wear down, this wheel guarantees that the finish you achieve on the first part is identical to the finish on the last, streamlining your production process and reducing rework.
