Built from solid carbide and coated with titanium carbonitride (TiCN), it delivers extended tool life in ferrous and non-ferrous materials. The 4-flute, right-hand flute geometry produces 1-8 UNC internal threads with a cutting diameter of 0.6210 inches and a length of cut of 1.9370 inches. Overall length is 4.2520 inches, and the 0.6250-inch shank seats directly into a standard milling chuck or collet holder. This tool is installed and operated by machinists and CNC programmers working in precision machining environments.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for CNC machining centers performing internal thread milling on workpieces requiring 1-8 UNC threads with a minimum nominal bore diameter of 1.0000 inch. Thread milling is preferred over tapping in hard materials, blind holes where chip evacuation is critical, or applications requiring close thread tolerance control. The helical flute design and TiCN coating support use in steel, alloy steel, cast iron, and similar materials at appropriate cutting parameters. Coolant-through capability is not available on this tool; flood or mist coolant applied externally at the cutting zone is recommended.\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\u003eTiCN coating reduces friction and extends tool life compared to uncoated carbide\u003c\/li\u003e\n\u003cli\u003e4 right-hand helical flutes for efficient chip evacuation during internal thread milling\u003c\/li\u003e\n\u003cli\u003eCuts 1-8 UNC internal threads in a single helical interpolation pass\u003c\/li\u003e\n\u003cli\u003e0.6250-inch shank diameter for compatibility with standard ER or milling chuck toolholders\u003c\/li\u003e\n\u003cli\u003eSeries 4128 designation for straightforward replacement and reorder identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct equivalent for Series 4128 helical flute thread mills producing 1-8 UNC internal threads with a 0.6250-inch shank.

Power down and lock out the machining center spindle before loading or unloading the tool from the toolholder. Secure the shank to the full recommended gauge length in the collet or chuck before tightening to manufacturer torque specifications for the toolholder type in use. Program helical interpolation at conservative entry feed rates and verify thread pitch and lead in the CAM output before first-part cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.6210 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.9370 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.2520 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 1.0000 inch\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eSeries\u003c\/strong\u003e: 4128\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.251 pounds\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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9041280254000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732771471666,"sku":"9041280254000","price":957.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1009dc4a661168b09744ec95d0e92874.jpg?v=1788746585","url":"https:\/\/voomisupply.com\/products\/guhring-9041280254000-thread-mill-1-8-unc-internal-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
