06W458 - Walter ALLSTEEL 4-1/2 Inch 80 Grit Zirconia Flap Disc Spin-On

High-Performance Zirconia Alumina Flap Disc

The Walter ALLSTEEL™ Flap Disc (SKU: 06W458) is engineered to provide industrial operators with a reliable and economical solution for heavy-duty metalworking tasks. This 4-1/2 inch disc features an 80 grit abrasive surface, making it an excellent choice for intermediate finishing and blending applications where a balance between material removal and surface finish is required. The disc utilizes a proprietary blend of zirconia alumina abrasive grains. This advanced material is designed to self-sharpen under pressure, fracturing to reveal fresh cutting edges. This mechanism ensures that the disc maintains a high removal rate throughout its lifespan, reducing operator fatigue and increasing throughput on the shop floor.

One of the standout features of the ALLSTEEL™ series is the trimmable backing. Unlike standard flap discs where the backing plate can interfere with the workpiece as the flaps wear down, the ALLSTEEL™ backing can be trimmed away. This unique design feature significantly extends the usable life of the disc, allowing operators to consume more of the abrasive material before discarding the unit. This translates to direct cost savings and fewer disc changes during long shifts. The Spin-On hub system further enhances efficiency by allowing for tool-free mounting and dismounting, minimizing downtime between abrasive changes.

Designed for versatility, this flap disc is optimized for use on both steel and stainless steel. It excels in demanding applications such as blending sharp corners, heavy deburring, and smoothing out fillet welds. The 80 grit configuration provides a smoother finish compared to coarser grits, preparing surfaces for painting or further finishing steps. Whether used in structural fabrication, tank manufacturing, or general maintenance and repair, the Walter ALLSTEEL™ 06W458 delivers consistent, industrial-grade performance.
