Manufactured from high-speed steel (HSS), this die holds a cutting edge under the heat and friction generated during threading operations. The 3-inch outside diameter fits standard die stocks and holders sized for 3-inch round dies. The adjustable design allows the technician to fine-tune thread fit by slightly opening or closing the die body using the set screws in the die stock. This die is used by machinists, pipefitters, and maintenance mechanics working with left-hand threaded fastener applications.\u003c\/p\u003e\n\u003cp\u003eLeft-hand UNF threading dies are used where reverse-rotation service conditions or vibration would loosen a standard right-hand thread. Common applications include industrial machinery components, specialty fastener fabrication, and repair work on equipment with intentional left-hand threaded assemblies. The 1-1\/2-12 thread form is a fine-pitch unified national fine thread, suited for applications requiring greater thread engagement strength or finer adjustment than a coarse-pitch thread provides. This die is appropriate for job shop, maintenance, and production threading work on steel, aluminum, and similar machinable materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-12 UNF thread form for fine-pitch external thread cutting\u003c\/li\u003e\n  \u003cli\u003eLeft-hand thread direction for reverse-thread applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for heat resistance and edge retention during threading\u003c\/li\u003e\n  \u003cli\u003e3-inch outside diameter fits standard 3-inch round die stocks\u003c\/li\u003e\n  \u003cli\u003eAdjustable body allows thread fit fine-tuning without changing tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or new tooling option for standard 3-inch round die stocks and holders that accept 3-inch OD round threading dies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSeat the die securely in the die stock and tighten all holding screws before beginning a threading pass. Apply cutting fluid generously to the workpiece and die to reduce heat buildup and extend tool life. Back off the die periodically during threading to clear chips and prevent galling. Left-hand dies require counter-clockwise rotation to advance the thread cut; confirm thread direction before starting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: 314-4512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697893081394,"sku":"314-4512","price":151.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a215e6be16000b226562cc730c49ed6c.jpg?v=1788355481","url":"https:\/\/voomisupply.com\/products\/value-collection-314-4512-round-die-1-1-2-12-unf-3-in-od-left-hand-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
