Built from submicron-grade solid carbide, it delivers the rigidity and wear resistance required for consistent thread form across production runs. The tool features 4 flutes, a cutting diameter of 0.29 inches, and a length of cut of 0.775 inches. A bright finish is applied to the flute geometry. Shank diameter is 5\/16 inches, and overall length is 3.5 inches. This mill is installed and operated by machinists and CNC programmers working in metalworking, toolroom, and production machining applications.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for internal thread milling of 3\/8-16 UNC threads in materials compatible with solid carbide tooling, including steel, stainless steel, aluminum, and cast iron. It is appropriate for use in vertical and horizontal machining centers where helical interpolation is available. The straight flute design makes it a practical choice for through-hole and blind-hole threading operations where chip evacuation requirements are moderate. No coolant-through capability is present, so external coolant or misting strategies should be planned accordingly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts internal 3\/8-16 UNC threads with a 16 TPI profile\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for extended tool life\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes with bright finish for clean thread form\u003c\/li\u003e\n  \u003cli\u003e0.29 inch cutting diameter with 0.775 inch length of cut\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch shank diameter for standard ER or precision collet chucks\u003c\/li\u003e\n  \u003cli\u003e3.5 inch overall length provides clearance for most standard setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for internal thread milling of 3\/8-16 UNC threads on CNC machining centers capable of helical interpolation.

Confirm runout on the tool holder before running to avoid thread form errors. Power down and lock out the spindle before making any tool changes. Consult the tool manufacturer or a speeds-and-feeds reference for appropriate cutting parameters for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 16 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.29 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.775 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStaggered Tooth\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM.290-16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51973424611634,"sku":"TM.290-16","price":231.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06201252ae1822a60b096b1b9013b958.jpg?v=1789973260","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tm-290-16-thread-mill-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
