15W456 - Walter ALLSTEEL 4.5 Inch Zirconia Flap Disc 60 Grit Type 27

High-Performance Zirconia Alumina Flap Disc for Steel

The Walter Surface Technologies ALLSTEEL™ flap disc (SKU: 15W456) represents a significant advancement in general-purpose abrasive solutions for industrial environments. Designed specifically for use on steel, this 4-1/2 inch disc utilizes a proprietary blend of Zirconia Alumina grain. This abrasive material is engineered to fracture under pressure, a process known as self-sharpening, which exposes fresh, sharp cutting edges throughout the life of the disc. This mechanism ensures a consistent removal rate and prevents the glazing often associated with lower-quality abrasives.

One of the standout features of the ALLSTEEL™ line is the trimmable backing. In standard flap discs, the abrasive cloth often wears down to the backing plate, leaving unused abrasive material near the center that must be discarded. The ALLSTEEL™ backing can be trimmed down, allowing the operator to utilize the full diameter of the flaps. This feature significantly extends the service life of each disc, reducing the frequency of changeovers and lowering overall consumable costs. The Type 27 profile provides a flat grinding surface, ideal for blending and finishing operations where control and surface consistency are paramount.

Constructed in Germany to rigorous quality standards, these discs are optimized for angle grinders and offer a balance of aggression and finish. The 60 grit configuration provides a versatile medium-coarse texture, suitable for both substantial stock removal and preparing surfaces for finer finishing steps. Whether used for heavy deburring, edge chamfering, or blending fillet welds, the 15W456 delivers reliable performance in demanding fabrication settings.

By integrating a high-performance grain blend with an economical design structure, Walter provides a solution that meets the needs of high-volume shops. The disc requires less pressure to cut effectively, reducing operator fatigue during extended grinding sessions. This efficiency, combined with the extended life provided by the trimmable backing, makes the ALLSTEEL™ an excellent choice for MRO and fabrication departments looking to optimize their abrasive inventory.
