12C421 - Walter 2-Inch Type 17 Grinding Cone 5/8-11 Thread

Heavy-Duty Industrial Grinding Plug

The Walter 12C421 is a premium Type 17 abrasive plug engineered for the most demanding industrial environments. Designed specifically for heavy stock removal, this 2-inch by 4-inch cone is an essential tool for foundries, steel mills, and heavy fabrication shops where material removal speed and tool life are critical. The Type 17 shape—a cone with a flat tip—allows operators to grind effectively in confined spaces, corners, and internal diameters that standard grinding wheels cannot reach.

One of the standout features of this product is its integrated internally threaded arbor (5/8"-11). This design eliminates the need for separate mounting hardware or adapters, allowing for direct, secure attachment to straight grinders. This not only simplifies the setup process but also ensures the abrasive runs true, minimizing vibration and enhancing operator safety. The robust bonding matrix holds the abrasive grain securely, providing a consistent cut rate throughout the life of the plug.

Constructed to withstand the rigors of aggressive grinding, the Walter 12C421 excels at smoothing weld seams, cleaning castings, and deburring heavy metal parts. It is formulated for compatibility with both steel and stainless steel, making it a versatile addition to any industrial abrasive inventory. Whether removing gates and risers in a foundry or blending heavy welds in a structural steel shop, this plug delivers the performance professionals demand.
