O-1 tool steel is a general-purpose oil-hardening grade known for its dimensional stability during heat treatment and its ability to hold a sharp cutting edge after hardening and tempering. This drill rod is used by machinists, toolmakers, and die makers as raw stock for fabricating punches, dies, reamers, drill blanks, and other precision tooling components. At 4.35 pounds, the bar offers substantial stock for multiple parts from a single length.\u003c\/p\u003e\u003cp\u003eThis drill rod is suited for job shops, tool rooms, and maintenance shops where custom tooling is produced in-house. The 45\/64-inch diameter fits applications requiring a near-three-quarter-inch round bar with tight dimensional tolerances. It is appropriate for both low-volume prototype work and short-run production tooling. Machinists working with manual or CNC lathes and mills will find this diameter useful for turning down to finished punch or reamer dimensions before heat treatment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eO-1 oil hardening tool steel grade for predictable, controlled heat treatment response\u003c\/li\u003e\n\u003cli\u003e0.703 inch (45\/64 inch) diameter provides near-three-quarter-inch stock with tight tolerance\u003c\/li\u003e\n\u003cli\u003e36-inch length supplies sufficient material for multiple tooling blanks per bar\u003c\/li\u003e\n\u003cli\u003eOil hardening process minimizes distortion and cracking risk compared to water-hardening grades\u003c\/li\u003e\n\u003cli\u003eTool steel composition supports high hardness after quench, suitable for cutting and forming tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as standard O-1 tool steel drill rod stock for use as raw material in fabricating punches, drill blanks, reamers, and other precision tooling where oil hardening grades are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and grinding O-1 tool steel drill rod should be performed by a qualified machinist using appropriate speeds and feeds for tool steel. Hardening requires controlled furnace heating followed by an oil quench — consult published heat treatment data for O-1 before processing. Wear appropriate PPE when cutting, grinding, or heat treating. Handle bar stock with care to avoid surface nicks that can become stress concentrators after hardening.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: O-1 Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTempering Medium\u003c\/strong\u003e: Oil Hardening (O-1)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 0.703 inches (45\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.35 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: O1D45646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51719235502386,"sku":"O1D45646","price":57.63,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e7898603713ab7f0876b8331281c64c.jpg?v=1788558300","url":"https:\/\/voomisupply.com\/products\/value-collection-o1d45646-o-1-drill-rod-45-64-in-tool-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
