The 90-degree V-angle accommodates round stock and cylindrical workpieces ranging from 1\/8 inch minimum to 19\/32 inch maximum capacity. V parallelism is held to 0.0002 inch and squareness to 0.0002 inch, making this block suitable for layout, grinding, drilling, and inspection setups where close tolerances matter. A clamp and wooden storage case are included. Machinists, toolmakers, and metrology technicians are the primary users of this type of precision workholding accessory.\u003c\/p\u003e\n\u003cp\u003eThis V-block suits bench-level workholding applications in precision machining and inspection environments. It handles cylindrical parts such as shafts, pins, and round stock within the stated capacity range. The compact overall footprint of 1-3\/8 inches long by 1-3\/8 inches wide by 1-3\/16 inches tall makes it practical for smaller-diameter workpiece setups. It is sold as an individual unit and is not part of a matched pair. Typical use cases include layout marking, surface plate inspection, drilling setups, and cylindrical grinding operations where a stable, accurate reference surface is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree V-angle for secure seating of round and cylindrical stock\u003c\/li\u003e\n  \u003cli\u003eHardened steel construction for wear resistance and long-term accuracy retention\u003c\/li\u003e\n  \u003cli\u003eV parallelism of 0.0002 inch for tight tolerance workholding and inspection\u003c\/li\u003e\n  \u003cli\u003eSquareness of 0.0002 inch ensuring precise perpendicular reference\u003c\/li\u003e\n  \u003cli\u003eCapacity range of 1\/8 inch minimum to 19\/32 inch maximum\u003c\/li\u003e\n  \u003cli\u003eIncludes clamp and wooden storage case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 90-degree V-block for bench-level precision workholding and inspection setups involving cylindrical workpieces within the 1\/8 inch to 19\/32 inch capacity range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachinists and toolmakers typically seat this V-block on a surface plate or machine table, securing the workpiece with the included clamp before performing layout or machining operations. Clean the mounting surface and block base thoroughly before use to prevent debris from affecting accuracy. Do not exceed the stated maximum capacity of 19\/32 inch, as overloading the V can compromise workpiece stability and block integrity. Store in the included wooden case when not in use to protect precision surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Capacity\u003c\/strong\u003e: 19\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Capacity\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eV Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eV Parallelism\u003c\/strong\u003e: 0.0002 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.0002 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMagnetic\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Clamp, Wooden Case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Individual\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111627\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 420-5421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693768311090,"sku":"420-5421","price":94.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da3d0d6d31ea445b0b2b055559fbd0d9.jpg?v=1788317124","url":"https:\/\/voomisupply.com\/products\/value-collection-420-5421-v-block-90-degree-hardened-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
