1-1/2" x 2-1/2" Type 18 Grinding Plug, 3/8"-11 Thread

Aggressive Metal Removal for Hard-to-Reach Spaces

When your grinding job takes you into tight corners, inside pipes, or deep into metal castings, standard grinding wheels just won't cut it. The Walter 1-1/2" x 2-1/2" Type 18 Grinding Plug is the professional's choice for internal grinding and snagging applications. Built to tackle the toughest steel and metal fabrication challenges, this plug combines aggressive cutting power with the durability needed for heavy industrial use. Its cylindrical shape with a flat face allows you to grind the bottom and sides of blind holes or smooth out internal welds with precision and control.

Built for Performance and Safety
Equipped with a standard 3/8"-11 threaded arbor, this grinding plug spins on quickly and securely to your straight grinder or die grinder. The direct-thread mount eliminates the slippage often associated with shank-mounted points, ensuring maximum power transfer from your tool to the workpiece. The coarse 16-grit abrasive grain bites into metal fast, rapidly removing excess material, weld spatter, and casting flash without bogging down. It is the ideal solution for foundries, shipyards, and structural steel shops where efficiency is key.

Smooth Operation
Vibration is the enemy of precision and comfort. Walter Surface Technologies engineers these plugs to be perfectly balanced, ensuring smooth rotation even at high speeds. This attention to detail means less chatter on the workpiece and less strain on your hands and arms. Whether you are cleaning up a flame-cut edge or prepping a surface for final finishing, this Type 18 plug provides the consistency and longevity you expect from a top-tier abrasive brand. Add the Walter 12C302 to your abrasive arsenal and experience the difference in quality and speed.
