Engineered with a premium Zirconia Alumina grain structure, this Type 18R plug delivers exceptional stock removal rates while maintaining a long service life. The coarse 16-grit composition makes it ideal for hogging off material, smoothing rough castings, and leveling heavy welds where speed and efficiency are paramount.<\/p>\n<p>One of the standout features of this grinding plug is its integrated 5\/8&#8243;-11 internal threaded arbor. This design allows for direct mounting onto straight grinders and die grinders without the need for separate collets or adapters, ensuring a secure fit and optimal concentricity. The direct mount system significantly reduces vibration, protecting both the tool bearings and the operator from fatigue during extended use. The 1-1\/2&#8243; diameter and 3&#8243; length provide a substantial surface area for working inside pipes, cylinders, and other confined spaces that are inaccessible to standard grinding wheels.<\/p>\n<p>Constructed with a robust resinoid bond, the 12C201 is formulated to withstand high pressure and heat generation. It is versatile enough to perform effectively on both mild steel and stainless steel, making it a staple in foundries, fabrication shops, and heavy manufacturing environments. Whether used for deburring, shaping, or heavy cleaning, this plug offers the aggressive bite required for rapid material removal.<\/p>\n<h3>Technical Specifications<\/h3>\n<ul>\n<li><strong>Dimensions:<\/strong> 1-1\/2&#8243; Diameter x 3&#8243; Length<\/li>\n<li><strong>Arbor:<\/strong> 5\/8&#8243;-11 Threaded Insert<\/li>\n<li><strong>Grain Type:<\/strong> Zirconia Alumina (ZA)<\/li>\n<li><strong>Grit:<\/strong> 16 (Extra Coarse)<\/li>\n<li><strong>Shape:<\/strong> Type 18R (Square End Plug)<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"Popular in foundaries, steel mills and fabricating shops for heavy stock removal in hard to reach areas.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[2000,2014],"product_tag":[],"class_list":["post-1750723","product","type-product","status-publish","product_cat-abrasives","product_cat-plugs-and-mounted-items","pa_arbor-in-5-8","pa_brand-walter","pa_diameter-in-1-5","pa_grit-6166","pa_item-brush","pa_length-in-4901","pa_packaging-description-1-in-a-pack","pa_used-to-grind-steel-or-stainless","first","onbackorder","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Walter 1-1\/2&quot; x 3&quot; Zirconia Grinding Plug 5\/8&quot;-11 Arbor - Josef Gas<\/title>\n<meta name=\"description\" content=\"Walter 12C201 Grinding Plug. 1-1\/2 inch x 3 inch Type 18R with 5\/8-11 threaded arbor.
