Angle blocks are hardened reference tools used in metrology, inspection, and machining setups to establish or verify precise angular relationships between workpiece surfaces or inspection fixtures. This block is hardened to 56 HRC, providing the surface durability required for repeated use in production and quality-control environments. An accuracy rating of 20 arc seconds makes it suitable for close-tolerance layout and inspection work. Machinists, tool-and-die makers, and quality technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis angle block is suited for use in machine shops, tool rooms, and inspection departments where small, precise angular offsets are needed for setups, sine plate work, or surface plate inspection routines. Its compact 3-inch length fits standard setups without overhanging critical reference surfaces. The 0.25-degree angle addresses fine-offset applications common in precision grinding and milling fixture work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFixed 0.25-degree angle for consistent, repeatable angular reference\u003c\/li\u003e\n\u003cli\u003e3-inch overall length fits standard machine and inspection setups\u003c\/li\u003e\n\u003cli\u003e56 HRC hardness resists wear and surface deformation with regular use\u003c\/li\u003e\n\u003cli\u003e20 arc-second accuracy rating supports close-tolerance inspection and layout\u003c\/li\u003e\n\u003cli\u003eSingle-piece solid construction with no moving parts to drift or loosen\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose precision angle block for use on surface plates, sine plates, and magnetic chucks in standard metrology and machining fixture applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAngle blocks are positioned and used by machinists or quality technicians — no power source or licensed trade certification is required for typical use. Clean the reference surfaces of both the block and the mating surface plate or fixture before each use to prevent burrs or debris from introducing angular error. Do not drop or impact the block against hard surfaces, as shock can alter hardness characteristics or introduce surface damage that degrades accuracy. Store in a protective case or on a padded surface when not in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 0.25 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 56 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 20 arc seconds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 630-0025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720594522418,"sku":"630-0025","price":31.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64d8eb8754ab0c0e6faf1af674b14005.jpg?v=1788566633","url":"https:\/\/voomisupply.com\/products\/value-collection-630-0025-angle-block-0-25-degree-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
