Walter 2-Inch Type 18R Grinding Plug with 5/8-11 Thread

Get Into Tight Spots with Aggressive Grinding Power

When you are dealing with a messy root pass inside a pipe or trying to clean up a heavy fillet weld in a tight corner, a standard 4.5-inch grinder just won't cut it. That is where the Walter 2" x 3" Grinding Plug (SKU 12C211) comes in. This Type 18R plug is built for the welder who needs to remove metal fast in places that are hard to reach. The rounded nose lets you dig into corners and curves without gouging the surrounding metal, giving you control where you need it most.

This plug screws directly onto your straight grinder or die grinder with a standard 5/8"-11 spindle. No fiddling with chucks or worrying about the stone slipping in a collet—just spin it on and you are ready to grind. It is designed to eat up steel and stainless steel, making it perfect for cleaning up castings, prepping heavy plate bevels, or smoothing out inside diameters. Walter is known for making abrasives that last, and this plug is no exception; it holds its shape well and keeps cutting even when you lean into it.

Stop struggling with worn-out burrs or undersized mounted points for big jobs. This heavy-duty plug gives you the mass and the grit to hog out material quickly, saving you time on cleanup and prep. Whether you are in a fab shop or out in the field, keeping a few of these 12C211 plugs in your gang box ensures you are ready for those awkward, heavy-grinding scenarios.
