Built from powdered metal and finished with a TiCN coating, this tool delivers wear resistance and edge retention across a range of ferrous and non-ferrous materials. The 3-flute geometry produces clean thread forms in a single helical pass. With a 0.115 inch cutting diameter, a 0.325 inch length of cut, and a 2.5 inch overall length, the TM115-32N fits standard CNC machining centers with a 1\/4 inch shank connection. Licensed machinists and CNC operators use this tool in production and job-shop environments where tap breakage risk or blind-hole access are concerns.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for internal threading operations in materials where a straight flute geometry provides adequate chip clearance and process stability. The 8 to 32 UNC specification makes it applicable to fastener holes in light mechanical assemblies, enclosures, fixtures, and instrumentation components. No coolant-through feature is present, so external flood or mist coolant is the standard approach. The 1\/4 inch shank accepts standard ER collet chucks and other common CNC toolholding systems used in vertical and horizontal machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts internal UNC threads from size 8 to 32 TPI in a single pass\u003c\/li\u003e\n  \u003cli\u003ePowdered metal substrate for improved wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e3-flute straight design provides process stability in CNC thread milling operations\u003c\/li\u003e\n  \u003cli\u003e0.115 inch cutting diameter with 0.325 inch length of cut for shallow-to-moderate thread depths\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank compatible with standard ER and shrink-fit toolholding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use thread mill for CNC machining centers equipped with 1\/4 inch shank toolholding systems capable of helical interpolation for internal UNC thread milling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread milling requires a CNC machine capable of helical interpolation  -  confirm controller support before setup. Secure the 1\/4 inch shank in a balanced, precision collet or toolholder to minimize runout, which directly affects thread quality. Apply external flood or mist coolant directed at the cutting zone, as this tool does not have coolant-through capability. Inspect the cutting edges before use and discard the tool at the first sign of chipping or coating wear to avoid thread form errors.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8 to 32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 32 TPI\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.115 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.325 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\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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: 0.04 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: TM115-32N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52004201955634,"sku":"TM115-32N","price":178.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ceb4eed1d8b96c7d19242ce26dcc49b6.jpg?v=1789999366","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tm115-32n-thread-mill-8-32-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
