Walter A-25 Grinding Stone for Steel

Smooth Control for Fitting and Finishing

When you are fitting up a joint or cleaning out a tight corner, you need a grinder bit that doesn't bounce around. The Walter A-25 Mounted Point (12D076) is built for welders and fabricators who demand control. Designed specifically for tough steel and cast iron, this grinding stone bites into the metal without the aggressive chatter found in cheaper alternatives. It is the perfect companion for your die grinder when you need to enlarge a bolt hole, prep a bevel in a tight spot, or smooth out a jagged edge on a flame-cut part.

The "Tough Steel" formulation means this stone is aggressive enough to remove stock quickly but durable enough to hold its shape. The A-25 ball shape is incredibly versatile—you can use it to grind radii, clean up inside pipes, or deburr complex shapes where a flap wheel or burr just won't fit. Because Walter balances these points so well, you get a smooth operation that reduces hand fatigue during long shifts.

Stop fighting with vibrating stones that ruin your finish and wear out your tools. Upgrade to the Walter 12D076 for a smoother grind. It is ideal for prep work before welding or cleaning up difficult-to-reach areas after the pass. Whether you are working on mild steel, heavy structural plate, or cast repairs, this mounted point delivers the performance professional welders expect.
