Built from submicron-grade solid carbide and finished with an AlTiN+ coating, it delivers consistent thread quality in ferrous and non-ferrous materials across high-cycle production environments. The tool runs on a 1\/4 inch shank, measures 2.5 inches in overall length, and carries a 0.235 inch cutting diameter with a 0.669 inch length of cut. Three straight flutes provide clean chip evacuation in blind and through-hole applications. Licensed machinists and CNC operators install this tool in milling centers for precise internal thread generation.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for precision machining operations requiring UNEF internal threads at 5\/16-32. Typical applications include aerospace, automotive, and industrial component manufacturing where thread tolerance and surface finish are critical. The tool is appropriate for CNC vertical and horizontal machining centers capable of helical interpolation. The straight flute geometry makes it a practical choice for short-chipping materials where staggered tooth designs are unnecessary. Coolant-through is not supported; flood or mist coolant applied externally is standard practice for this tool class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-32 UNEF internal thread profile in a single helical pass\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide substrate for extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating provides heat resistance and reduced friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eThree straight flutes for efficient chip evacuation in blind and through holes\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank diameter compatible with standard ER and end mill holders\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup on machines without internal coolant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread mill for CNC machining centers capable of helical interpolation, accepting a 1\/4 inch shank tool holder and programmed for 5\/16-32 UNEF internal thread cycles.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified CNC machinists or tooling setup technicians. Secure the 1\/4 inch shank in a properly sized collet or end mill holder and verify runout before cutting. Program the machining center for helical interpolation using the 0.235 inch cutting diameter and 32 TPI pitch values provided by the manufacturer. Do not use this tool in manual milling operations or in machines that do not support helical interpolation, as improper motion will damage the thread form and the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-32\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: UNEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 32 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.235 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.669 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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\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\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\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: TM235-32A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52086614786354,"sku":"TM235-32A","price":167.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6a4a49b13f5e33885c2d6a7a1165fea.jpg?v=1790059789","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tm235-32a-thread-mill-5-16-32","provider":"Voomi Supply","version":"1.0","type":"link"}
