It features a solid carbide construction with 3 flutes and a bright finish, producing clean thread forms at 32 teeth per inch (TPI). The 1\/4-inch shank diameter keeps it compatible with standard collet toolholding systems. A cutting diameter of 0.126 inches and a length of cut of 0.512 inches make it well-suited for threading smaller-diameter holes, while the 2.244-inch overall length provides adequate reach in typical machining setups. Machinists and CNC operators use this tool where tapping is impractical or where a single tool must produce multiple thread sizes.\u003c\/p\u003e\u003cp\u003eThis thread mill is intended for internal thread applications in ferrous and non-ferrous materials where UNC or UNF thread standards are required. It is suited for use in CNC machining centers capable of helical interpolation. The minimum nominal thread diameter supported is No. 8 (number 8). Typical applications include precision components requiring clean, accurate internal threads without the breakage risk associated with solid taps in difficult materials or blind holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003e3 straight flutes for efficient chip evacuation during internal thread milling\u003c\/li\u003e\n\u003cli\u003e32 TPI for UNC and UNF thread standard compatibility\u003c\/li\u003e\n\u003cli\u003e0.126-inch cutting diameter with 0.512-inch length of cut for small-diameter internal threads\u003c\/li\u003e\n\u003cli\u003eBright finish  -  no coating  -  suitable for applications where coatings are not required or preferred\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design; external coolant or cutting fluid applied at the spindle\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for internal thread milling operations conforming to UNC and UNF thread standards, compatible with CNC machining centers using helical interpolation and standard 1\/4-inch collet or toolholder systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation of this tool should be performed by a qualified machinist or CNC operator. Ensure the tool is properly seated and secured in a 1\/4-inch collet or toolholder before spindle engagement. Verify that the CNC program uses the correct helical interpolation path and feed rate for the target thread size and material. Inspect the cutting edges for wear or chipping before each use, as solid carbide tooling can chip if subjected to interrupted cuts or excessive runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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 (TPI)\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.126 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.512 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.244 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: No. 8\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStaggered Tooth\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: 80250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67907347579186,"sku":"80250","price":251.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9fb98941d5ee4b633e51eaddb628b4d.jpg?v=1791177930","url":"https:\/\/voomisupply.com\/products\/vargus-80250-internal-thread-mill-32-tpi-1-4-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
