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

Smooth Blending and Long Life for Steel Fabrication

As a welder, you know that the quality of your finish is just as important as the strength of your weld. The Walter 15W708 ALLSTEEL™ 7-inch Flap Disc is designed to help you achieve that professional finish on steel projects without breaking the bank. Whether you are cleaning up spatter, blending a fillet weld, or deburring a freshly cut steel plate, this disc provides the consistency and control you need. The 80 grit abrasive is the sweet spot for welders who need to smooth out rough areas but leave a surface finish that is refined enough for final inspection or painting.

One of the biggest frustrations in the shop is throwing away a flap disc that still has good abrasive in the center just because the edge is worn out. Walter solves this problem with their trimmable backing technology. When the flaps wear down to the edge of the backing plate, you can simply trim the plastic backing to expose unused abrasive layers. This means you get more grinding time out of every single disc, saving you trips to the tool crib and keeping money in your pocket. It is a smart design choice that makes a real difference in daily shop life.

The Zirconia Alumina grain used in the ALLSTEEL™ series is tough and aggressive. Unlike standard sanding discs that can clog or heat up quickly, these grains fracture cleanly to keep cutting cool and fast. This is particularly important when working on larger steel assemblies where heat buildup can be an issue. The 7-inch size covers more ground quickly, making it perfect for long seams and large structural beams. It fits standard 7-inch grinders with a 7/8-inch arbor, so you can slap it on and get straight to work.

Choose the Walter ALLSTEEL™ for your general-purpose steel grinding needs. It offers the bite you need to remove material efficiently and the finesse required for a clean blend, all backed by Walter’s reputation for quality and safety. It is the economical choice that doesn't feel 'cheap' when you are behind the grinder.
