It produces a 1-1\/2-18 UNEF (Unified Extra Fine) right-hand thread profile and features an adjustable design that allows the technician to fine-tune thread fit by slightly expanding or compressing the die across its split. High-speed steel construction provides the hardness and heat resistance needed for threading ferrous metals at production feed rates without premature edge breakdown. This die is used by machinists, maintenance mechanics, and tool-and-die tradespeople working on precision assemblies where a fine thread pitch is required.\u003c\/p\u003e\n\u003cp\u003eThe 315-1583 is suited for applications that require a 1-1\/2-inch nominal diameter thread at 18 threads per inch, a pitch commonly found in precision mechanical assemblies, hydraulic fittings, and instrumentation hardware. The extra-fine UNEF thread standard provides maximum thread engagement for thin-walled parts and applications where vibration resistance or fine adjustment is critical. This die is appropriate for use in both job-shop and maintenance environments where consistent, repeatable thread cutting is required on low to medium production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-18 UNEF thread profile for extra-fine pitch external threading\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction resists heat buildup and edge wear during threading operations\u003c\/li\u003e\n  \u003cli\u003eAdjustable split-die design allows thread fit to be dialed in for tolerance control\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction matches standard fastener and fitting conventions\u003c\/li\u003e\n  \u003cli\u003eSingle-piece round die format fits standard die stocks and holders sized for this OD\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard round die stocks and holders that accept dies of the corresponding outer diameter.

Secure the die fully in the holder before beginning a threading pass, and apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Start the die squarely on the workpiece to prevent cross-threading and uneven wear. Follow shop safety practices and relevant OSHA machine-shop guidelines when operating threading tools.\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\/2-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNEF (Unified Extra Fine)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112805\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: 315-1583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695672754482,"sku":"315-1583","price":140.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d00c186ec9d501e09a06ea0d3e817179.jpg?v=1788337321","url":"https:\/\/voomisupply.com\/products\/value-collection-315-1583-round-die-1-1-2-18-unef-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
