06W456 - Walter ALLSTEEL 4.5 Inch 60 Grit Zirconia Spin-On Flap Disc

Walter ALLSTEEL™ 4-1/2" Spin-On Flap Disc - 60 Grit

The Walter ALLSTEEL™ 4-1/2" Flap Disc (SKU: 06W456) represents a high-performance, economical solution for industrial grinding and finishing applications. Designed by Walter Surface Technologies, a leader in abrasive innovation, this disc is engineered to provide a superior removal rate on both steel and stainless steel surfaces. The 60 grit configuration makes it an excellent middle-ground choice, capable of substantial stock removal while leaving a manageable finish that prepares the surface for subsequent steps or final coating.

At the core of the ALLSTEEL™ performance is a special zirconia alumina abrasive grain blend. Unlike standard aluminum oxide discs that can dull quickly, zirconia alumina is known for its self-sharpening properties. As the disc is used, the abrasive grains fracture to reveal new, sharp cutting edges. This mechanism allows the operator to maintain a high cut rate with less pressure, reducing fatigue during long shifts. This specific blend is optimized for general-purpose metal fabrication, making it a versatile tool for workshops handling diverse materials.

One of the most practical features of this product is the Spin-On mounting system. The integrated 5/8"-11 threaded hub allows for rapid attachment to standard angle grinders without the need for locking nuts or pin wrenches. This not only speeds up disc changes but also reduces vibration, resulting in a smoother operation. Furthermore, the ALLSTEEL™ line features a trimmable backing. As the abrasive flaps wear down, the plastic backing can be trimmed back to expose unused abrasive material near the center of the disc. This unique design feature significantly extends the usable life of the product, ensuring you get the maximum value out of every disc in the box.

Whether you are blending sharp corners, performing heavy deburring, or smoothing out fillet welds, the Walter ALLSTEEL™ provides consistent, industrial-grade results. It is the economical choice for professionals who refuse to compromise on quality and safety.
