Drill blanks are precision-ground cylindrical rods used as the raw stock for custom toolmaking, gage pins, punches, and special-purpose tooling. At 0.3680 inch in decimal diameter and 5 inches overall length, this blank gives machinists and tool-and-die tradespeople the material they need to grind or lap a finished tool to exact specifications. The bright finish indicates no additional heat or chemical coating has been applied, preserving the as-ground surface and dimensional integrity of the steel.\u003c\/p\u003e\n\u003cp\u003eThis drill blank is suited for tool rooms, machine shops, and manufacturing maintenance departments where custom tooling is fabricated in-house. It is appropriate for applications requiring a Letter U diameter, including jig boring, precision punching, and fixture tooling. Machinists working in both general metalworking and close-tolerance production environments use blanks of this type as starting stock for grinding operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter U size — 0.3680 inch decimal diameter for standard letter-series applications\u003c\/li\u003e\n  \u003cli\u003e5 inches overall length provides sufficient stock for most single-tool grinding operations\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction offers good hardness and wear resistance for toolmaking use\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish preserves as-ground surface dimensions\u003c\/li\u003e\n  \u003cli\u003eSold individually — no minimum bundle required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Letter U drill blank compatible with standard toolroom grinding and fabrication workflows requiring a 0.3680 inch diameter HSS blank at 5 inches overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDrill blanks are raw stock and require grinding or lapping before use as finished tools. Machining and grinding of high speed steel should be performed by qualified tool-and-die or machine shop personnel using appropriate wheel speeds and coolant to prevent overheating and loss of hardness. Secure the blank properly in a tool-and-cutter grinder or surface grinder fixture before any material removal. Inspect the blank for surface defects before beginning grinding operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Blank Size (Letter)\u003c\/strong\u003e: U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Blank Size (Decimal Inch)\u003c\/strong\u003e: 0.3680 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1583 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242100\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: 63323240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703326409010,"sku":"63323240","price":22.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9afec1c2e46c788c9c88e80df34b628.jpg?v=1788416063","url":"https:\/\/voomisupply.com\/products\/value-collection-63323240-drill-blank-letter-u-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
