It cuts right-hand threads with a 60-degree profile angle, covering a range of 36 to 48 threads per inch (TPI) with a minimum threading diameter of 0.1575 inches. The tool has an overall length of 1.1811 inches and a cutting depth of 0.5906 inches. A TiCN and TiN dual-layer coating provides wear resistance and lubricity during high-speed threading passes. This tool is intended for use by machinists and toolroom professionals working on precision internal threading applications.\u003c\/p\u003e\u003cp\u003eThis threading tool is suited for internal threading of small bores in ferrous and non-ferrous materials on CNC lathes and machining centers. The 0.1575-inch minimum threading diameter makes it appropriate for fine-pitch, tight-bore applications common in precision component manufacturing, instrument parts, and threaded insert preparation. The right-hand thread direction and 60-degree profile angle are standard for unified and metric thread forms in this pitch range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in internal threading\u003c\/li\u003e\n\u003cli\u003eCovers 36 to 48 TPI range with a 60-degree profile angle\u003c\/li\u003e\n\u003cli\u003eTiCN and TiN coating for extended tool life and reduced friction\u003c\/li\u003e\n\u003cli\u003e0.1575-inch minimum threading diameter for small-bore applications\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, standard for unified and metric fine-pitch threads\u003c\/li\u003e\n\u003cli\u003e0.02-inch projection from edge for controlled depth placement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit threading tool for CNC lathes and machining centers that accept solid carbide single point threading inserts with a 4.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before mounting or changing the tool. Verify shank diameter compatibility with the toolholder bore before seating the tool. Coolant-through is not supported on this tool; use external coolant or cutting fluid directed at the cutting zone as needed per shop practice.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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: 0.1575 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch Range\u003c\/strong\u003e: 36 to 48 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 0.5906 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.1811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection from Edge\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection from Center\u003c\/strong\u003e: 0.0591 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlat Width\u003c\/strong\u003e: 0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN and TiN\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: 0.02 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6402444\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51747433939250,"sku":"6402444","price":82.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d68e60b50bef5480ed5bbc496f4e316c.jpg?v=1788880134","url":"https:\/\/voomisupply.com\/products\/iscar-6402444-internal-single-point-threading-tool","provider":"Voomi Supply","version":"1.0","type":"link"}
