These hardened steel blocks serve as a reliable reference tool for setting up workpieces on mills, drill presses, and surface plates. The standardized 1-inch by 2-inch by 3-inch dimensions make them a go-to for squaring parts, supporting workholding fixtures, and establishing parallel or perpendicular reference planes. Machinists, tool and die workers, and fabricators rely on 1-2-3 blocks as a fundamental shop measurement and setup aid. The included plastic case keeps the blocks protected and organized between uses.\u003c\/p\u003e\n\u003cp\u003e1-2-3 blocks are a standard setup tool in machine shops, fabrication facilities, and metalworking environments. They are used when milling, drilling, grinding, or performing layout work that requires a known, repeatable reference surface. The plastic case makes this set practical for tool crib storage or transport between work areas. This set is appropriate for both production and maintenance machining applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStandardized 1-inch by 2-inch by 3-inch block dimensions for predictable, repeatable setups\u003c\/li\u003e\n  \u003cli\u003eHardened construction for resistance to wear and deformation under clamping pressure\u003c\/li\u003e\n  \u003cli\u003ePlastic carrying case included for organized storage and block protection\u003c\/li\u003e\n  \u003cli\u003eSold as a set for immediate use in paired or stacked configurations\u003c\/li\u003e\n  \u003cli\u003eSuitable for use on mills, drill presses, surface plates, and welding fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose precision setup tool compatible with standard machining and fabrication workholding applications where 1-2-3 block references are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003e1-2-3 blocks are a hand-placed setup tool and do not require permanent installation. Machinists and fabricators should inspect block faces for burrs or debris before use to ensure accurate seating against reference surfaces. Keep blocks clean and lightly oiled when stored to prevent surface corrosion. Handle with care to avoid dropping, which can chip hardened surfaces and compromise dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: JET\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 630400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JET","offers":[{"title":"Default Title","offer_id":51342982349106,"sku":"630400","price":84.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310501053.jpg?v=1782012732","url":"https:\/\/voomisupply.com\/products\/jet-630400-1-2-3-block-set-plastic-case","provider":"Voomi Supply","version":"1.0","type":"link"}
