With a 0.302-inch cutting diameter, a 0.407-inch length of cut, and a 0.313-inch shank diameter, this tool handles tapered pipe thread profiles with consistent accuracy. The 4-flute, right-hand configuration combined with an EgiAs coating improves tool life and chip evacuation in demanding machining environments. It is intended for use by machinists and tool-and-die professionals working in CNC milling operations where NPT thread forms are required.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for shops producing or servicing components that require NPT pipe thread connections, including fittings, manifolds, valve bodies, and hydraulic or pneumatic housings. The helical flute geometry allows the tool to interpolate threads in a single pass using standard CNC circular interpolation cycles, making it practical for both production runs and low-volume precision work. The compact cutting diameter and short length of cut make it appropriate for tight-clearance bores common in fluid-system components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/8-27 NPT thread form for tapered pipe thread applications\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eEgiAs coating extends tool life in abrasive and hard materials\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand helical design for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eHandles both internal and external thread milling in a single tool\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup on standard machining centers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CNC machining centers capable of helical interpolation.

Ensure the tool holder is properly torqued and the shank is fully seated before running the spindle. Program the tool path using circular interpolation (G02 or G03) per the machine control requirements for the NPT thread helix angle. Verify workpiece fixturing is secure and spindle runout is within tolerance before cutting, as carbide tooling is sensitive to lateral deflection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8-27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 27 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.302 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.407 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: EgiAs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16630\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1663000117\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730549244210,"sku":"1663000117","price":262.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9b17beafb22a147a80f0ff47baff9f9_1394ac01-e40a-470b-82d2-fdbe79b4884c.jpg?v=1788719411","url":"https:\/\/voomisupply.com\/products\/osg-1663000117-thread-mill-1-8-27-npt-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
