06W512 - Walter Allsteel 5-Inch 120 Grit Spin-On Flap Disc

Achieve Flawless Finishes with Walter Allsteel 5" Flap Discs

For welders and fabricators who demand precision and speed, the Walter 06W512 Allsteel™ Flap Disc is a top-tier solution for steel finishing. When your project requires a smooth, professional look after heavy grinding or welding, this 120 grit disc steps in to refine the surface effortlessly. Built with a high-performance zirconia alumina grain blend, the Allsteel disc cuts cool and fast, reducing the risk of heat discoloration on your workpiece while smoothing out ridges and blending weld seams.

The 5-inch diameter provides excellent coverage and control, while the 120 grit is specifically suited for finishing applications. It excels at blending sharp corners, heavy deburring where a finer finish is required, and preparing steel for final coating or polishing. One of the standout features for the busy welder is the Spin-On 5/8"-11 hub. This built-in threaded arbor means you can spin the disc onto your angle grinder in seconds—no hunting for a wrench or losing flange nuts in the shop dust. It centers perfectly every time, reducing vibration and operator fatigue during extended use.

Walter has also solved the common problem of wasted abrasive with their innovative trimmable backing. As the flaps wear down on the edge, you can trim the backing material to expose unused abrasive towards the center of the disc. This not only extends the life of the disc but also allows the flexible flaps to conform better to curved surfaces and reach into fillet welds. Whether you are working on structural steel, automotive frames, or general fabrication, the Walter Allsteel 06W512 delivers the reliability and finish quality professional welders trust.
