Each block measures 1 inch wide, 2 inches long, and 3 inches tall, with a squareness tolerance of 0.0003 inches and an overall dimensional tolerance of 0.0001 to 0.0007 inches. The blocks are hardened to 58-60 HRC for long-term wear resistance and dimensional stability. Machinists, tool and die makers, and precision grinders rely on 1-2-3 blocks as fundamental workholding and referencing tools.\u003c\/p\u003e\u003cp\u003eThese blocks are used in milling, grinding, drilling, and layout operations where accurate right-angle reference and workpiece support are required. Common applications include setting up vises and fixtures, supporting workpieces on surface plates, checking squareness, and acting as gauge references during precision grinding operations. Sold as a matched pair, they are suited for use together when parallel support or mirrored setups are needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSquareness tolerance of 0.0003 inches for accurate right-angle referencing\u003c\/li\u003e\n\u003cli\u003eOverall dimensional tolerance of 0.0001 to 0.0007 inches\u003c\/li\u003e\n\u003cli\u003eHardened steel construction at 58-60 HRC for durability and wear resistance\u003c\/li\u003e\n\u003cli\u003eStandard 1 x 2 x 3 inch format compatible with common fixturing and workholding setups\u003c\/li\u003e\n\u003cli\u003eSold as a matched pair for parallel or mirrored setup applications\u003c\/li\u003e\n\u003cli\u003eSuitable for layout work and precision grinding operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1-2-3 block format for use in general machining, toolroom, and inspection environments where hardened steel setup blocks are required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of 1-2-3 blocks is typically performed by machinists and toolroom professionals. Always deburr and clean mating surfaces before placing blocks to ensure accurate contact. Handle hardened steel blocks with care to avoid edge chipping. Store blocks in a protective case or on a clean, dry surface to maintain surface integrity and dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlock Type\u003c\/strong\u003e: 1-2-3 Block\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Tolerance\u003c\/strong\u003e: 0.0001 to 0.0007 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 58 to 60 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Matched Pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.6 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 6630-4008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689656516914,"sku":"6630-4008","price":69.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f70b3024bd4e9606befa67338b2f979.jpg?v=1788262528","url":"https:\/\/voomisupply.com\/products\/value-collection-6630-4008-1-2-3-setup-block-hardened-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
