Constructed from submicron-grade solid carbide with a bright, uncoated finish, this tool delivers rigidity and wear resistance in small-diameter threading applications. It features a 0.05-inch cutting diameter, a 0.028-inch neck diameter, and a 0.15-inch neck length, making it well suited for fine-pitch, miniature thread work where dimensional accuracy is critical. With 3 flutes and a 1\/8-inch shank, it is compatible with standard CNC machining centers and milling spindles.\u003c\/p\u003e\u003cp\u003eThis thread mill is intended for use in precision machining environments where both internal and external threads must be produced in a single tool setup. Typical applications include small fastener threads, instrument components, and miniature hardware in aerospace, medical device, and electronics manufacturing. The single-profile design allows one tool to cover the full 64 to 80 TPI range without a tool change, reducing setup time in multi-thread-size jobs. It is installed and operated by CNC machinists and tooling specialists working with small-diameter features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts both internal and external threads from 64 to 80 TPI with a single tool\u003c\/li\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for rigidity in fine-pitch applications\u003c\/li\u003e\n\u003cli\u003e0.05-inch cutting diameter suited for miniature and small-diameter thread forms\u003c\/li\u003e\n\u003cli\u003e0.028-inch neck diameter and 0.15-inch neck length for access in tight bore profiles\u003c\/li\u003e\n\u003cli\u003e3-flute geometry for chip clearance in both through and blind hole threading\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with a range of cutting fluids and coolants\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNC milling machines and machining centers accepting a 1\/8-inch shank diameter.

Confirm runout at the spindle before engaging the cut, as small-diameter carbide tools are sensitive to excessive runout. Use manufacturer-recommended feeds, speeds, and cutting fluid for the workpiece material. Handle solid carbide tooling carefully to avoid chipping the cutting edges during setup and storage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size Range\u003c\/strong\u003e: 1-64 to 1-80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 64 to 80\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: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.05 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.028 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SPTM050L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52112130834738,"sku":"SPTM050L","price":77.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7c580be067de1935b9cfa39ab0325c7.jpg?v=1790077460","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-sptm050l-thread-mill-64-80-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
