O-1 tool steel is a general-purpose oil hardening grade known for its ease of machining in the annealed state and its ability to hold a precise ground diameter after heat treat. This rod is used as raw stock for fabricating punches, dies, dowel pins, arbors, and other precision tooling components. Machinists, toolmakers, and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill rod is appropriate for job shop, maintenance, and production toolroom applications where tight dimensional tolerances on bar stock are required before or after heat treatment. The 36-inch length provides a full working blank suitable for single-piece or short-run tooling. It is well suited to both manual and CNC lathe operations where the ground OD serves as a reference surface for chucking or steady-rest support.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eO-1 oil hardening tool steel grade for predictable heat treat response and minimal distortion\u003c\/li\u003e\n\u003cli\u003eGround outer diameter held to 0.3280 inches for close-tolerance fitment in tooling applications\u003c\/li\u003e\n\u003cli\u003e36-inch overall length provides ample stock for multiple tooling blanks per bar\u003c\/li\u003e\n\u003cli\u003eAnnealed condition allows conventional machining before final hardening and tempering\u003c\/li\u003e\n\u003cli\u003eSold as a single rod with no minimum order beyond one piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O-1 tool steel drill rod blank for use wherever a 21\/64-inch diameter ground rod is required in toolmaking, maintenance machining, or repair applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and grinding of tool steel rod should be performed with appropriate coolant to prevent localized overheating that can affect material properties. Heat treatment including hardening and oil quench should be carried out by a qualified toolmaker or heat treat technician following established practice for O-1 grade steel. Always use proper workholding and eye protection when parting or turning drill rod stock on a lathe or mill.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter (Fraction)\u003c\/strong\u003e: 21\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter (Decimal)\u003c\/strong\u003e: 0.3280 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTempering Medium \/ Grade\u003c\/strong\u003e: O-1 Oil Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.861 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: O1D21646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691786600754,"sku":"O1D21646","price":20.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f4a2fd908bb024fb89a44070a99d4b2.jpg?v=1788289660","url":"https:\/\/voomisupply.com\/products\/value-collection-o1d21646-o-1-drill-rod-21-64-in-36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
