Built from solid carbide, this toolholder accepts five 3UI-style inserts held in place by screw clamping, delivering repeatable thread form accuracy across production runs. With a cutting diameter of 2.09 inches and a maximum hole depth capacity of 11.811 inches, it handles deep-bore internal threading where rigidity and coolant delivery are critical. Through-coolant capability keeps the cutting zone clear and helps extend insert life during extended passes. This tool is installed and operated by machinists and CNC programmers in job shop, aerospace, and industrial manufacturing settings.\u003c\/p\u003e\u003cp\u003eThe 67751 is suited for internal threading applications on CNC milling centers and machining cells where a TMSC-D toolholder style is specified. Its right-hand cutting direction and five-flute configuration support efficient material removal in a range of workpiece materials. The 0.75-inch arbor hole diameter and 1.77-inch neck diameter define the spindle interface and clearance envelope, making it important to confirm fitment with the target machine spindle and workholding setup before programming. Typical applications include threading large-bore holes in structural components, fixtures, and heavy industrial assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide toolholder construction for rigidity in deep-bore threading\u003c\/li\u003e\n\u003cli\u003eAccepts five 3UI indexable inserts secured by screw clamping for fast changeover\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design directs fluid to the cutting zone to manage heat and chip evacuation\u003c\/li\u003e\n\u003cli\u003e2.09-inch cutting diameter with 11.811-inch maximum hole depth capacity for deep internal threading\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with five-flute geometry for balanced thread milling passes\u003c\/li\u003e\n\u003cli\u003eTMSC-D toolholder style with 0.75-inch arbor hole for standardized machine interface\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3UI-style indexable threading inserts with a 0.375-inch insert size in TMSC-D toolholder configurations on CNC milling machines capable of helical interpolation for internal thread milling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread mills must be installed and programmed by qualified machinists familiar with helical interpolation cycles on CNC milling equipment. Confirm spindle taper, arbor diameter, and toolholder projection before setup. Power down and lock out the machine spindle before changing inserts or adjusting the toolholder. Do not exceed the tool's rated maximum hole depth, and verify through-coolant pressure is within the machine and toolholder specifications before running.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 2.09 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Hole Depth\u003c\/strong\u003e: 11.811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.58 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 1.77 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3UI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Threading Inserts\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: TMSC-D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: 11.51 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291800\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: 67751\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67911750844722,"sku":"67751","price":769.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04bbdb8a310fbb34864e6107ec650a55.jpg?v=1791218700","url":"https:\/\/voomisupply.com\/products\/vargus-67751-indexable-thread-mill-2-09in-internal-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
