Made from high-speed steel, it handles the heat and wear demands of production and maintenance threading work. This die cuts a 1-3\/8-18 thread profile to the UNEF (Unified Extra Fine) standard with a right-hand thread direction. The adjustable design allows the operator to fine-tune the fit and compensate for minor wear over the life of the die. Machinists, toolmakers, and maintenance mechanics use round dies like this one for chasing damaged threads or cutting new threads on rod, bolt blanks, and custom fastener stock.\u003c\/p\u003e\n\u003cp\u003eThis die is suited for threading operations in machine shops, maintenance facilities, and manufacturing environments where UNEF thread profiles are specified. The 1-3\/8-18 size is common in precision mechanical assemblies, instrumentation hardware, and aerospace-adjacent work where finer thread pitch is needed on larger-diameter stock. It is used with a standard round die stock holder sized for the die's outer diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/8-18 thread size in the UNEF (Unified Extra Fine) standard\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction — standard for most fastener applications\u003c\/li\u003e\n  \u003cli\u003eAdjustable die body allows thread fit tuning and compensates for wear\u003c\/li\u003e\n  \u003cli\u003eRound die profile fits standard die stock holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for use with round die stock holders that accept dies of this profile.

Secure the die in the holder using the set screws before beginning any threading operation. Apply cutting oil to the workpiece before and during threading to reduce heat buildup and extend die life. Do not force the die over stock that exceeds the nominal thread diameter without first confirming the workpiece is properly sized.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/8-18\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\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: 315-1563\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723045634354,"sku":"315-1563","price":135.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e477f5ef65cbd40e7eeb3e29abe0f4f5.jpg?v=1788599769","url":"https:\/\/voomisupply.com\/products\/value-collection-315-1563-round-die-1-3-8-18-hss-unef","provider":"Voomi Supply","version":"1.0","type":"link"}
