With a 3\/16-inch shank diameter and three right-hand helical flutes, this tool mills UNF and UNEF internal threads at 32 teeth per inch (TPI). The cutting diameter is 0.1500 inches with a length of cut (LOC) of 0.3910 inches and an overall length (OAL) of 1.7720 inches. A bright, uncoated finish keeps the carbide substrate exposed for applications where coating buildup or heat sensitivity is a concern. Coolant-through capability supports chip evacuation and tool life during continuous threading operations.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for job shops, aerospace component machining, and precision manufacturing environments where CNC milling centers perform internal threading in lieu of tapping. It handles three common thread sizes in one tool: 10-32, 12-3\/8, and 8-32, reducing the need for multiple taps or dedicated tooling per size. It is installed and operated by machinists and CNC programmers running interpolated helical milling cycles on vertical or horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in precise thread milling\u003c\/li\u003e\n\u003cli\u003eThree right-hand helical flutes for smooth cutting action on internal threads\u003c\/li\u003e\n\u003cli\u003eCoolant-through design aids chip evacuation and thermal management during threading\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for applications requiring bare carbide performance\u003c\/li\u003e\n\u003cli\u003eMachines 10-32, 12-3\/8, and 8-32 internal threads with a single tool\u003c\/li\u003e\n\u003cli\u003eConforms to UNF and UNEF thread standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for internal thread milling on CNC machining centers capable of helical interpolation; compatible with 10-32, 12-3\/8, and 8-32 UNF and UNEF thread forms as specified in the input data.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread mills of this type are installed in a collet or end mill holder matching the 3\/16-inch shank diameter on a CNC machining center capable of helical interpolation cycles. Verify spindle runout is within acceptable limits before use, as carbide thread mills are sensitive to runout and deflection at small diameters. Confirm correct coolant-through pressure and flow is active before beginning the threading cycle. Always reference the machine tool builder documentation and applicable shop standards when programming helical interpolation paths.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Sizes\u003c\/strong\u003e: 10-32, 12-3\/8, 8-32\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: UNF, UNEF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 32 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.1500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.3910 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.7720 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 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: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\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: 80291\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67906109735218,"sku":"80291","price":189.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3999cc65fcf0fb1ce1cea09d879d732a.jpg?v=1791165034","url":"https:\/\/voomisupply.com\/products\/vargus-80291-helical-flute-thread-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
