Built from micrograin solid carbide and coated with TiCN for extended tool life and heat resistance, this four-flute mill produces right-hand internal threads at 24 teeth per inch. With an overall length of 2.9920 inches and a cutting diameter of 0.2910 inches, it is sized for tight-tolerance thread milling on CNC machining centers. Licensed machinists and CNC operators install this tool in precision metalworking and manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for internal thread milling operations on CNC mills and machining centers where a single tool must produce clean, accurate 3\/8-24 UN internal threads. It is typically used in aerospace, automotive, and general manufacturing settings where thread quality and tool longevity are critical. The helical flute geometry promotes chip evacuation during cutting. Coolant-through is not supported on this tool, so external coolant or air blast is the standard approach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating extends tool life and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003eFour helical flutes promote efficient chip evacuation during internal thread milling\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction for standard CNC thread milling programs\u003c\/li\u003e\n\u003cli\u003eCuts 3\/8-24 UN internal threads at 24 TPI\u003c\/li\u003e\n\u003cli\u003eNo coolant-through channels  -  compatible with external coolant or air blast setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation for internal thread milling operations in the 3\/8-24 UN thread standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation of this tool is performed by qualified CNC machinists or tooling specialists. Secure the shank in a precision collet or tool holder rated for the shank diameter before use. Verify spindle speed and feed rate settings in the CNC program against the material being threaded before running the tool. External coolant or air blast should be directed at the cutting zone since this tool does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\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: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 24 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.2910 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9920 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2.9920 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VARGUS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 80541\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67912293155122,"sku":"80541","price":235.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4af45bb783fdd97bc1e8a4a5fdc35470_cd6b4cf6-baaa-4d6b-8377-956aa1b56d0f.jpg?v=1791232099","url":"https:\/\/voomisupply.com\/products\/vargus-80541-thread-mill-3-8-24-internal-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
