15E166 - Walter Two-in-One Mounted Flap Wheel 3 Inch Extra Fine

Technical Overview: Walter 15E166 Two-in-One Flap Wheel

The Walter 15E166 is a specialized abrasive tool designed for industrial metalworking applications requiring both material removal and surface conditioning. Part of the renowned Two-in-One series, this 3-inch diameter mounted flap wheel features a unique construction that interleaves flaps of high-quality coated abrasive cloth with flaps of non-woven Blendex material. This hybrid configuration allows the wheel to perform two distinct functions simultaneously: the abrasive cloth cuts down surface imperfections, light welds, or scratches, while the non-woven material blends the surface to a smooth, uniform finish.

With dimensions of 3 inches in diameter and 1-3/4 inches in width, this wheel is mounted on a standard 1/4-inch shaft, making it compatible with most pneumatic and electric die grinders. The "Extra Fine" grade specification indicates its suitability for final finishing stages where a low Ra (Roughness Average) is required. The wheel is engineered to run cool, mitigating the risk of heat buildup that can lead to warping or discoloration, particularly on heat-sensitive alloys like stainless steel. The flexibility of the flap configuration ensures consistent contact with the workpiece, even on irregular or contoured surfaces.

This product is an essential consumable for fabrication shops focused on efficiency. By consolidating the grinding and finishing steps, operators can reduce tool changeover time and inventory requirements. The 15E166 is rated for a maximum speed of 8,000 RPM, ensuring safe and effective operation within standard die grinder parameters. It is compatible with a wide range of materials, including stainless steel, carbon steel, and aluminum, making it a versatile addition to any MRO or fabrication inventory.
