OVERVIEW

Achieve Flawless Finishes with Walter ALLSTEEL™

For welders who demand both speed and finish quality, the Walter 15W512 ALLSTEEL™ 5" Flap Disc is a workshop essential. This 120 grit abrasive disc is designed to take your steel projects from a rough weld to a smooth, professional finish in record time. Built with a high-performance zirconia alumina grain blend, it offers a superior cut rate compared to traditional sanding discs, making it ideal for blending welds, cleaning up spatter, and preparing surfaces for final aesthetic treatments.

The 120 grit rating places this disc in the finishing category, perfect for the final stages of fabrication where surface appearance matters most. The zirconia grains are tough and durable, fracturing under pressure to maintain a sharp cutting edge. This self-sharpening action means you don't have to push as hard to get the job done, saving your arms from fatigue during long grinding sessions. It excels on steel, cutting cool and fast without gouging the base metal, ensuring that your workpiece retains its structural integrity and dimensional accuracy.

Value is a critical factor for any welder, and the ALLSTEEL™ series delivers with its innovative trimmable backing. Standard flap discs often get thrown away with plenty of abrasive left because the backing plate gets in the way. With this Walter disc, you can simply trim the backing to expose more of the 120 grit flaps, effectively giving you a "second life" for the same disc. This smart design feature means fewer disc changes, less downtime, and more money kept in your pocket.

Compatible with standard 5-inch angle grinders using a 7/8-inch arbor, the 15W512 is versatile enough for a wide range of applications. From smoothing out fillet welds to deburring cut edges, it provides a consistent, scratch-free finish. If you are looking for a flap disc that works as hard as you do and helps you achieve that perfect showroom shine on steel fabrications, the Walter ALLSTEEL™ is the tool for the job.
