12C211 - Walter 2-Inch Type 18R Grinding Plug with 5/8-11 Thread

Heavy-Duty Material Removal for Industrial Applications

The Walter 12C211 Type 18R Grinding Plug is an industrial-grade abrasive tool engineered for the most demanding material removal tasks found in steel mills, foundries, and heavy fabrication shops. Measuring 2 inches in diameter and 3 inches in length, this plug features a Type 18R geometry, characterized by a cylindrical body with a rounded nose. This specific shape allows operators to aggressively grind internal contours, heavy fillets, and irregular surfaces that are inaccessible to standard grinding wheels or flap discs.

Constructed with a high-performance abrasive matrix, this plug is formulated to maintain a high cut rate throughout its lifespan while resisting glazing, even under heavy pressure. The internal 5/8"-11 threaded arbor is a critical safety and efficiency feature, allowing for direct mounting onto straight grinders without the need for separate adapters or collets. This direct connection ensures concentricity, significantly reducing vibration and run-out. Lower vibration levels not only improve the surface finish but also reduce mechanical stress on the power tool and physical fatigue for the operator during extended shifts.

Designed primarily for steel and stainless steel applications, the Walter 12C211 excels in deburring large castings, smoothing out heavy weld seams in confined spaces, and preparing surfaces for subsequent finishing. Its robust resinoid bond structure ensures structural integrity at high rotational speeds, making it a reliable choice for aggressive stock removal operations where safety and performance are paramount.
