It handles a thread range of 18 to 56 threads per inch (TPI) with a minimum threading diameter of 0.18 inches and a cutting depth of 0.75 inches. The 60-degree profile angle suits standard thread forms. At 2.5 inches overall length with a 0.25-inch shank, this tool mounts in standard boring bar holders and CNC lathe turrets. It is used by machinists and toolroom technicians working on precision internal threading operations in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis tool is suited for internal threading on CNC lathes and manual engine lathes where tight bore diameters and fine-to-coarse thread ranges are required. The solid carbide construction supports harder workpiece materials and higher cutting speeds compared to high-speed steel alternatives. The bright uncoated finish keeps the tool ready for use as supplied and is appropriate for threading aluminum, brass, mild steel, and similar materials. A projection of 0.04 inches from the edge provides the clearance geometry needed for accurate thread chasing in confined bore conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal threading tool with 60-degree profile angle for standard thread forms\u003c\/li\u003e\n  \u003cli\u003eThread range: 18 to 56 TPI\u003c\/li\u003e\n  \u003cli\u003eMinimum threading diameter of 0.18 inches for small-bore applications\u003c\/li\u003e\n  \u003cli\u003e0.75-inch cutting depth for reaching threads inside deep bores\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish  -  no additional prep required before use\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design; external coolant application applies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for standard 0.25-inch shank boring bar holders used in CNC lathe and manual lathe turret setups requiring internal single point threading capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Secure the 0.25-inch shank in a compatible tool holder and confirm proper tool height alignment to centerline before threading. Power down and lock out the spindle before inserting or removing the tool. Do not exceed the tool manufacturer recommended depth of cut or feed rate for the workpiece material being threaded.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfile Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Threading Diameter\u003c\/strong\u003e: 0.18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Threads Per Inch\u003c\/strong\u003e: 18 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Threads Per Inch\u003c\/strong\u003e: 56 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection from Edge\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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: 0.01 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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TT180750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51971197632818,"sku":"TT180750","price":54.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c904fb088555021b0fe988d3767f588f_5975c575-bfcf-4149-82b8-db5923bb3242.jpg?v=1789954523","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tt180750-threading-tool","provider":"Voomi Supply","version":"1.0","type":"link"}
