The block is 3 inches long and ground to 55 HRC hardness, which provides durability and resistance to wear during repeated use. Accuracy is rated to 20 arc seconds, making this block suitable for tight-tolerance setups. Machinists, toolroom technicians, and quality control personnel use angle blocks to establish precise angular reference surfaces when grinding, milling, or inspecting workpieces.\u003c\/p\u003e\u003cp\u003eThis angle block is sized for benchtop and surface plate use in toolrooms, job shops, and manufacturing environments. The 15-degree angle covers a common setup requirement for chamfered parts, angled surfaces, and compound fixtures. Its compact 3-inch length fits standard vises and magnetic chucks without overhang issues. The hardened steel construction holds its geometry under clamping loads and normal shop-floor conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15-degree fixed angle for repeatable angular setups\u003c\/li\u003e\n\u003cli\u003e55 HRC hardness resists wear and maintains accuracy over time\u003c\/li\u003e\n\u003cli\u003e20 arc-second accuracy for tight-tolerance machining and inspection\u003c\/li\u003e\n\u003cli\u003e3-inch overall length suits most benchtop and surface plate applications\u003c\/li\u003e\n\u003cli\u003eCompact single-piece construction with no moving parts to go out of adjustment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose angle block for use with surface plates, sine bars, magnetic chucks, and milling vises in standard toolroom and machining setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAngle blocks are set up by toolroom machinists and quality technicians — no power tools or trade licenses are required. Clean the reference surfaces of both the angle block and the workholding device before use to remove chips, oil, and debris that could affect angular accuracy. Do not use the block as a striking surface or clamp against it with excessive force, as this can alter ground surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 15 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: 55 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: 630-4315\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700509606194,"sku":"630-4315","price":31.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa28135e56b74599735ba75f807893cf.jpg?v=1788391304","url":"https:\/\/voomisupply.com\/products\/value-collection-630-4315-angle-block-15-degree-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
