The Walter Surface Technologies 12C321 is a high-performance Type 18 grinding plug designed for the rigors of industrial metalworking. Measuring 2 inches in diameter and 3 inches in length, this abrasive tool is engineered to tackle heavy stock removal in confined spaces where traditional grinding wheels cannot reach. It features a coarse 24-grit aluminum oxide composition, making it exceptionally effective for grinding steel and stainless steel components.<\/p>\n
One of the standout features of this product is its integrated 5\/8″-11 internal threaded arbor. This design allows the plug to be mounted directly onto the spindle of compatible angle grinders and die grinders, bypassing the need for separate collets, chucks, or adapters. This direct mounting system not only saves setup time but also ensures a more secure connection, reducing run-out and vibration during high-speed operation. The result is a smoother grinding experience that enhances operator control and safety.<\/p>\n
Ideally suited for foundries, fabrication shops, and maintenance departments, this grinding plug excels at smoothing rough castings, removing flashing, cleaning internal pipe diameters, and blending weld seams in corners. The resinoid bond structure provides excellent structural integrity, allowing the plug to maintain its shape and cutting aggression throughout its service life. With a maximum speed rating of 15,800 RPM, it delivers rapid material removal rates, helping to optimize workflow efficiency in demanding production environments.<\/p>\n
