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

Economical and Durable Grinding Solution

Welders and fabricators looking for a hardworking abrasive that won't break the bank turn to the Walter ALLSTEEL™ Flap Disc. This 4-1/2 inch, 80 grit disc is built to handle the daily grind of the welding shop. Whether you are cleaning up a messy weld, taking down sharp edges on cut steel, or prepping a surface for final finishing, the 06W458 is up to the task. The 80 grit abrasive is perfect for when you need to remove material but also want to leave a relatively smooth surface profile, bridging the gap between heavy grinding and fine sanding.

What sets this disc apart is its smart design focused on longevity and ease of use. The Spin-On hub is a favorite among welders because it eliminates the need for locking nuts and pin wrenches—just spin it on your angle grinder and you are ready to work. Inside the disc, the special zirconia alumina grain blend does the heavy lifting. It self-sharpens as you grind, meaning you don't have to push as hard to get the metal moving. This keeps the heat down and speeds up your work, especially on tough materials like stainless steel.

Stop throwing away flap discs that still have life in them. The Walter ALLSTEEL™ features a trimmable backing pad. As the abrasive flaps wear down, you can trim the plastic backing to expose fresh abrasive that sits closer to the center of the disc. This feature alone can drastically extend the life of each disc, giving you more grind time for your money. Ideal for blending fillet welds and working in tight corners, this disc is a versatile addition to any welder's arsenal.
