Built from submicron-grade solid carbide and coated with AlTiN+, it delivers consistent thread form and extended tool life in ferrous and high-hardness workpiece materials. With 4 flutes, a 0.290-inch cutting diameter, and a 0.775-inch length of cut, this tool is suited for CNC machining centers running rigid tapping or helical interpolation cycles. It is installed and operated by machinists and CNC programmers working in production, job shop, or toolroom environments.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is configured for internal UNC thread applications at 16 teeth per inch. The 5\/16-inch shank diameter and 3.5-inch overall length make it compatible with standard ER or shrink-fit toolholders on vertical and horizontal machining centers. It is a practical choice for shops threading blind holes, through-holes, or materials where tap breakage is a concern. No coolant-through capability is present, so flood or mist coolant delivery at the spindle is the appropriate approach for chip evacuation and heat management.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStraight flute geometry optimized for internal 3\/8-16 UNC thread milling\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide substrate for wear resistance and rigidity\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating for elevated-temperature performance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e4 flutes with 16 teeth per inch for clean thread form and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003e0.775-inch length of cut accommodates a range of thread depths in a single pass\u003c\/li\u003e\n  \u003cli\u003eNon-staggered tooth configuration for straightforward programming and predictable chip load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread milling tool for internal 3\/8-16 UNC applications on CNC machining centers equipped with helical interpolation.

Secure the shank in a balanced, runout-minimized toolholder  -  excessive runout will degrade thread quality and reduce tool life. Program the helical interpolation cycle to match the 3\/8-16 UNC pitch before spindle engagement. Apply flood or mist coolant externally, as this tool does not have coolant-through capability.\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\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: 0.290 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 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\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN+\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\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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: TM290-16A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52079973826866,"sku":"TM290-16A","price":233.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e2de09eaec281579e79e0f172a0d5cb_2b1997ff-59e1-4402-aa6e-049b09b0ede3.jpg?v=1790055225","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tm290-16a-thread-mill-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
