Built from micrograin solid carbide and coated with TiCN, it delivers extended tool life and thermal resistance in demanding machining environments. The three-flute design balances chip evacuation and surface finish on internal thread forms. Coolant-through capability supports high-speed applications where heat and chip buildup are concerns. This tool is used by machinists and toolmakers working on CNC machining centers where thread milling is preferred over tapping for precision, tool life, or access reasons.\u003c\/p\u003e\u003cp\u003eThread mills like the 80307 are suited for production and job-shop environments where a single tool must produce a range of thread depths, or where threading into blind holes requires controlled chip removal. The 5\/8-18 UNF thread specification makes it applicable to aerospace, hydraulic, and precision mechanical assemblies. Right-hand flute direction and a 5\/8 inch shank diameter are compatible with standard ER and other CNC toolholding systems. The TiCN coating provides hardness and lubricity advantages over uncoated carbide when working in ferrous and nonferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts 5\/8-18 UN internal threads at 18 TPI in a single helical interpolation pass\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves wear resistance and reduces friction in ferrous and nonferrous materials\u003c\/li\u003e\n\u003cli\u003eCoolant-through design aids chip evacuation and thermal control in deep internal thread applications\u003c\/li\u003e\n\u003cli\u003eThree right-hand flutes balance cutting forces and surface finish on internal thread forms\u003c\/li\u003e\n\u003cli\u003e1.25 inch length of cut accommodates typical thread depths for 5\/8-18 fastener engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers with standard toolholding systems accepting a 5\/8 inch shank diameter.

Verify toolholder runout and clamping torque per toolholder manufacturer specifications before use. Always confirm spindle speed, feed rate, and helix pitch in the CAM program match the tool geometry before cutting. Handle carbide tooling carefully to avoid chipping the cutting edges during setup and storage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\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: 18\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\u003eCutting Diameter\u003c\/strong\u003e: 0.5550 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.6220 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.418 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: VARGUS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 80307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67909910036786,"sku":"80307","price":396.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2079778192a24603011961797e4b0877_837cf796-80ee-4d92-9eef-90291d5bcfd5.jpg?v=1791193838","url":"https:\/\/voomisupply.com\/products\/vargus-80307-thread-mill-5-8-18-internal-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
