Built from submicron-grade solid carbide and finished with a TiN coating, this tool delivers consistent thread geometry and extended tool life in demanding machining environments. It produces 27 TPI threads and covers two common NPT pipe thread sizes: 1\/16-27 and 1\/8-27. With a cutting diameter of 0.222 inches and a 0.461-inch length of cut, it is suited for compact bore profiles where precision thread engagement is critical. Machinists and tool and die professionals use this tool on CNC machining centers running helical interpolation cycles.\u003c\/p\u003e\u003cp\u003eThis thread mill is used in precision machining shops producing fittings, manifolds, instrumentation housings, and fluid system components that require NPT pipe threads. The ability to cut both internal and external threads with a single tool reduces tooling inventory and changeover time. The 1\/4-inch shank diameter allows mounting in standard collet chucks and shrink-fit holders commonly found on vertical and horizontal machining centers. Right-hand flute direction suits standard spindle-forward helical interpolation programming.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts both 1\/16-27 NPT and 1\/8-27 NPT threads with one tool\u003c\/li\u003e\n\u003cli\u003eSubmicron-grade solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e3 right-hand helical flutes for smooth chip evacuation and stable cutting action\u003c\/li\u003e\n\u003cli\u003e0.222-inch cutting diameter suited for small-bore NPT thread applications\u003c\/li\u003e\n\u003cli\u003e2.5-inch overall length provides clearance for typical fixture and workpiece setups\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 1\/4-inch shank compatible with standard ER collet chucks, milling chucks, and shrink-fit toolholders.

Secure the 1\/4-inch shank in a properly sized collet or toolholder to the manufacturer-recommended clamping torque for the holder type in use. Verify spindle speed, feed rate, and helical interpolation radius match the thread mill diameter and target thread class before cutting. Coolant-through is not supported on this tool; apply flood or mist coolant externally as appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Sizes\u003c\/strong\u003e: 1\/16-27, 1\/8-27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 27 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.222 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.461 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eBrandstrong\u0026gt;: SCIENTIFIC CUTTING TOOLS\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TMX222-27-HC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52067051176242,"sku":"TMX222-27-HC","price":181.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a88a8b79c593f8436076e23d59edc5e1.jpg?v=1790045986","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmx222-27-hc-npt-thread-mill-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
