06W504 - Walter Allsteel 5-Inch 40 Grit Zirconia Flap Disc with Spin-On Hub

Industrial Grade Zirconia Flap Disc for Steel

The Walter 06W504 Allsteel™ Flap Disc is a premium abrasive solution engineered specifically for the rigorous demands of industrial steel fabrication. Designed with a proprietary blend of zirconia alumina abrasive grains, this 5-inch disc delivers an exceptional removal rate while maintaining a consistent surface finish throughout its lifespan. The self-sharpening properties of the grain ensure that the disc remains aggressive, cutting through heavy scale, weld seams, and rough surfaces without glazing over, even under heavy pressure.

One of the standout features of the Allsteel series is the innovative trimmable backing. Unlike traditional fiberglass-backed discs that must be discarded once the outer edge wears down, the Allsteel backing can be trimmed to expose fresh abrasive material closer to the center. This design significantly extends the usable life of the product, offering a better cost-per-weld ratio for high-volume shops. The backing is durable yet flexible enough to absorb vibration, providing a smoother operation that protects both the tool and the operator.

Efficiency is further enhanced by the integrated Spin-On mounting system. This 5/8"-11 threaded hub allows for rapid, tool-free disc changes, minimizing downtime between tasks. Whether used for heavy deburring, edge chamfering, or blending fillet welds, the Walter 06W504 provides a reliable, high-performance solution for working with structural steel and other ferrous metals. It is optimized for use with 5-inch angle grinders and is rated for safe operation at high RPMs.

Key Applications:

• Heavy stock removal on steel surfaces
• Blending and finishing fillet welds
• Deburring sharp edges and corners
• Surface preparation and scale removal
