15W458 - Walter ALLSTEEL 4.5 Inch x 7/8 Inch 80 Grit Zirconia Flap Disc

Walter ALLSTEEL™ 15W458 Flap Disc Overview

The Walter ALLSTEEL™ 15W458 is a high-performance 4-1/2" x 7/8" flap disc designed to deliver exceptional results on steel surfaces. Engineered with a specialized zirconia alumina abrasive grain blend, this disc is the ideal choice for industrial operators seeking a balance between aggressive removal rates and economic value. The 80 grit configuration makes it perfect for intermediate finishing, blending, and smoothing out rough surfaces after heavy grinding.

One of the standout features of the ALLSTEEL™ series is its self-sharpening capability. Unlike standard abrasives that dull quickly, the zirconia alumina grains fracture under pressure to reveal new, sharp cutting edges. This mechanism ensures that the disc maintains a high removal rate throughout its lifespan while requiring less physical pressure from the operator. This reduces fatigue during extended use and increases overall shop productivity.

Durability is further enhanced by the innovative trimmable backing. As the abrasive material wears down on the outer edge, the backing can be trimmed back to expose fresh abrasive cloth that would otherwise go unused. This feature significantly extends the service life of each disc, making the 15W458 a highly economical choice for high-volume fabrication environments. Whether you are performing heavy deburring, blending sharp corners, or working within tight fillet welds, the ALLSTEEL™ flap disc provides consistent, reliable performance.

Manufactured in Germany, this product represents Walter's commitment to quality and safety in abrasive technologies. It is compatible with standard 4-1/2 inch angle grinders featuring a 7/8 inch arbor. For maintenance, repair, and operations (MRO) professionals who demand efficiency and longevity from their consumables, the Walter ALLSTEEL™ 15W458 is a superior solution for all general purpose steel applications.
