With a cutting diameter of 0.098 inches, a shank diameter of 0.1875 inches (3\/16 inches), and an overall length of 2 inches, this tool is built for precision threading in tight bores and shallow profiles. The 4-flute geometry and bright uncoated finish make it suitable for a range of workpiece materials where coating buildup or heat sensitivity is a concern. Machinists and toolroom operators use this cutter where a single tool must handle multiple thread pitches without a tool change.\u003c\/p\u003e\u003cp\u003eThis thread mill is used in CNC machining centers for generating unified 6-32 and 6-40 thread forms in both through and blind holes, as well as on external bosses. The single profile design allows one tool to produce a range of pitches by adjusting the programmed helical path, reducing tooling inventory for shops running mixed thread specifications. The 0.050-inch neck diameter and 0.625-inch neck length provide the reach and clearance needed for internal threading applications where axial access is limited.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts internal and external threads from 6-32 to 6-40 (32 to 40 TPI) with a single tool\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003e4-flute design for balanced cutting forces during helical interpolation\u003c\/li\u003e\n\u003cli\u003e0.098-inch cutting diameter suited for small-diameter thread milling\u003c\/li\u003e\n\u003cli\u003e0.050-inch neck diameter with 0.625-inch neck length for reach into confined bores\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation, with a 3\/16-inch straight shank compatible with standard collet chucks and end mill holders of the appropriate bore size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation of this tool should be performed by qualified machinists familiar with CNC thread milling cycles and helical interpolation programming. Confirm spindle speed, feed rate, and radial depth of cut against the manufacturer published speeds and feeds before running. Ensure the tool holder is properly torqued and the collet bore matches the 0.1875-inch shank diameter to prevent runout. Inspect the cutting edges before each use, as solid carbide thread mills are sensitive to chipping from interrupted cuts or improper entry moves.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size Range\u003c\/strong\u003e: 6-32 to 6-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 32 to 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\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: 0.098 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.050 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\u003eWeight\u003c\/strong\u003e: 0.03 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: 993920\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51742123163954,"sku":"993920","price":161.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec502d8d4b5342249c77fa446c3a5366_e9279e6f-9d0e-4d03-88f5-ae640e62674a.jpg?v=1788835399","url":"https:\/\/voomisupply.com\/products\/harvey-tool-993920-thread-mill-6-32-to-6-40-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
