06W504 - Walter Allsteel 5-Inch 40 Grit Zirconia Flap Disc with Spin-On Hub

Aggressive Grinding with Maximum Comfort

Welders know that time is money, and the Walter Allsteel™ 5-Inch Flap Disc (06W504) is built to save you both. With a coarse 40 grit zirconia alumina formulation, this disc is designed to chew through steel rapidly, making short work of heavy weld beads and slag. Unlike cheaper alternatives that require you to lean hard into the grinder, the Allsteel disc cuts freely with minimal pressure. This reduces operator fatigue during long shifts and helps prevent heat buildup that can warp your workpiece.

The 06W504 features Walter's convenient Spin-On hub system. Forget hunting for a pin wrench every time you need to swap grits or replace a worn disc; simply spin the old one off and the new one on by hand. This secure, vibration-free connection improves safety and comfort, allowing for more precise control during delicate blending tasks. The 5-inch diameter provides excellent coverage for larger surfaces while remaining maneuverable enough for tight spaces.

Durability is a hallmark of the Walter brand, and this flap disc is no exception. It features a unique trimmable backing plate. As the flaps wear down on the outside, you can trim the plastic backing to reveal unused abrasive material underneath, effectively giving the disc a second life. This feature makes the Allsteel 06W504 one of the most economical choices for professional welders who demand consistent performance on carbon steel projects.
