It features a 3-flute helical geometry that produces clean thread forms while reducing cutting forces compared to single-point threading methods. The tool runs a 0.150-inch cutting diameter with a 0.500-inch length of cut, making it well suited for through and blind hole threading in tight bores. With a bright uncoated finish and 32 teeth per inch, it delivers consistent thread geometry in a range of workpiece materials. Installed by machinists and tool and die professionals, this mill is a direct replacement for tap-based threading in CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis thread mill is intended for internal threading operations on CNC machining centers where helical interpolation is available. It targets 10-32 UNF thread forms in materials where solid carbide tooling is preferred, including steel, aluminum, and stainless. The 3\/16-inch (0.1875-inch) shank diameter keeps the tool compact for small-bore work. A minimum nominal bore diameter of 0.190 inches applies, so verify bore clearance before use. No coolant-through capability is present; flood or mist cooling is recommended at the spindle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in metalworking applications\u003c\/li\u003e\n\u003cli\u003e3-flute helical design reduces cutting forces and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003e0.150-inch cutting diameter suits small-bore internal threading\u003c\/li\u003e\n\u003cli\u003e0.500-inch length of cut accommodates standard thread depth requirements for 10-32 UNF\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a broad range of base materials\u003c\/li\u003e\n\u003cli\u003e32 TPI matches 10-32 UNF thread specification exactly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for internal 10-32 UNF thread milling on CNC machining centers capable of helical interpolation; requires a minimum nominal bore diameter of 0.190 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists on CNC machining centers using helical interpolation cycles — confirm your CAM or controller supports this before programming. Power down the spindle and secure the tool with the correct collet or tool holder rated for the 0.1875-inch shank before tightening. Do not use this tool in manual or non-interpolating drilling operations. Apply flood or mist coolant externally, as this tool does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 32\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: 0.1500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.1900 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 987136\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51731039977778,"sku":"987136","price":273.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85d8b871c9949fea967463ff6e1d8ec6.jpg?v=1788726167","url":"https:\/\/voomisupply.com\/products\/harvey-tool-987136-thread-mill-10-32-internal-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
