It features a 0.138-inch cutting diameter paired with a 1\/4-inch shank diameter and a 2.5-inch overall length, making it well-suited for threading operations in tight bores and confined workspaces. The tool cuts a 24-pitch UN thread form and is built for use in CNC machining centers where repeatability and insert changeability reduce downtime. Machinists and tool-and-die professionals who need consistent thread geometry without dedicated single-purpose taps will find this format efficient for low-to-medium volume runs.\u003c\/p\u003e\n\u003cp\u003eThis thread mill fits into standard milling operations on CNC machining centers running UN-thread specifications. The 24-pitch designation covers fine-thread applications common in precision mechanical assemblies, instrumentation, and tight-tolerance fastener work. The compact 0.138-inch cutting diameter allows entry into small-diameter bores where full-profile thread mills with larger shanks cannot reach. This tool does not require coolant-through capability, making it compatible with a broad range of standard spindle setups without special coolant adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.138-inch cutting diameter for threading in small-bore and tight-clearance applications\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch shank diameter fits standard collets and tool holders on CNC machining centers\u003c\/li\u003e\n  \u003cli\u003e2.5-inch overall length provides reach while maintaining rigidity in the spindle\u003c\/li\u003e\n  \u003cli\u003e24-pitch UN thread form for fine-thread precision machining applications\u003c\/li\u003e\n  \u003cli\u003eMaximum cutting length of 0.42 inches supports thread depth requirements in typical fastener engagement zones\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup and broadens compatible spindle types\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an indexable thread mill for CNC machining center applications requiring a 1\/4-inch shank and 24-pitch UN thread form milling capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this tool should be performed by a qualified machinist or CNC operator familiar with thread milling cycles and toolpath programming. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool from the holder. Verify collet or tool holder runout is within acceptable limits before beginning a thread milling operation, as excessive runout directly affects thread quality. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool offsets and cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.138 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Length\u003c\/strong\u003e: 0.42 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (2-1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Milling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.044 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291800\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: MTSH0250C4224UN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51992079106354,"sku":"MTSH0250C4224UN","price":254.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16cc60212a096ed0618be559a46d5933.jpg?v=1789990099","url":"https:\/\/voomisupply.com\/products\/carmex-mtsh0250c4224un-indexable-thread-mill-24-pitch-un","provider":"Voomi Supply","version":"1.0","type":"link"}
