It features a 0.075 inch cutting diameter, a 0.25 inch shank diameter, and a 0.2 inch length of cut, making it a mini thread mill suited for small-diameter internal threading operations. The TiAlN coating provides thermal resistance during high-speed cutting. With 3 flutes and 48 teeth per inch, it produces accurate thread profiles in a single helical pass. Licensed machinists and CNC programmers install this tool in vertical or horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used in precision machining environments where small internal threads must be cut in hard or abrasive materials. It is appropriate for production and job-shop settings machining components that require number 3 or number 4 UNC or UNF internal threads. The left-hand and right-hand flute direction compatibility and mini thread mill classification make it suitable for tight-clearance bore applications in both prototype and production runs. Material grade MT7 supports use in a range of workpiece materials common to general and precision machining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with TiAlN coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eCuts number 3 and number 4 UNC and UNF internal threads at 48 TPI\u003c\/li\u003e\n  \u003cli\u003eMini thread mill classification for small-diameter and tight-clearance bores\u003c\/li\u003e\n  \u003cli\u003e3-flute design supports chip evacuation in confined internal features\u003c\/li\u003e\n  \u003cli\u003eCompatible with left-hand and right-hand helical flute directions\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies toolholder setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for internal thread milling of number 3 and number 4 UNC and UNF threads in CNC machining center applications.

The machine spindle must be stopped and the tool changer in a safe state before loading or unloading the tool. Verify runout with a dial indicator after seating in the collet or toolholder before running a program. Follow the tool manufacturer and machine builder guidelines for feed rate and spindle speed based on workpiece material and thread size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3 and 4 (Inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC, UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 48 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.075 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Left Hand, Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: MT7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Mill Type\u003c\/strong\u003e: Mini\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: CARMEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S0250C2048UN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51980057575730,"sku":"S0250C2048UN","price":266.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6101dcbed15a18295bc96d857c1a4e4e.jpg?v=1789981272","url":"https:\/\/voomisupply.com\/products\/carmex-s0250c2048un-thread-mill-3-4-internal-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
