15W708 - Walter ALLSTEEL 7-Inch Flap Disc 80 Grit Zirconia with Trimmable Backing

Industrial-Grade Zirconia Flap Disc for Steel Applications

The Walter 15W708 ALLSTEEL™ Flap Disc represents a high-efficiency solution for industrial grinding and finishing operations. Engineered specifically for steel surfaces, this 7-inch abrasive disc utilizes a premium Zirconia Alumina grain structure. This abrasive material is renowned in the MRO and fabrication sectors for its self-sharpening properties; as the grains fracture during use, they expose new, sharp cutting edges. This mechanism ensures that the disc maintains a consistent removal rate and finish quality throughout its service life, preventing the glazing and dulling often associated with lower-quality aluminum oxide discs.

A defining feature of the Walter ALLSTEEL™ line is the trimmable backing. In standard flap discs, the backing plate often prevents the operator from utilizing the inner portion of the abrasive flaps once the outer edge wears down. Walter’s innovative design allows the backing to be trimmed down, exposing fresh abrasive material that would otherwise be discarded. This feature significantly extends the usable life of the product, translating to lower consumable costs and reduced downtime for disc changes in high-volume production environments.

With an 80 grit rating, this specific SKU is optimized for intermediate finishing tasks. While coarser grits are used for heavy stock removal, the 80 grit configuration is ideal for blending fillet welds, smoothing out sharp corners after cutting, and preparing steel surfaces for painting or coating. The 7-inch diameter provides a large contact area, making it suitable for heavy-duty angle grinders and larger workpieces where speed and coverage are critical. The disc mounts securely via a standard 7/8-inch arbor, ensuring compatibility with most industrial angle grinders on the market.

Operators in structural steel fabrication, general manufacturing, and maintenance will find the 15W708 to be a reliable workhorse. It delivers the aggressive cut needed for steel while offering the control required for finishing, all within an economical package that does not compromise on safety or durability.
