It targets right-hand internal threads from 36 to 48 TPI with a 60-degree profile angle, making it suitable for fine-pitch work in confined geometries. The minimum threading diameter is 0.1181 inches, the cutting depth reaches 0.315 inches, and the overall length is 0.8661 inches. A TiAlN coating provides heat and wear resistance during dry or semi-dry machining. This tool is used by machinists and toolroom technicians working on CNC lathes, mills, or screw machines where small internal thread forms are required.\u003c\/p\u003e\n\u003cp\u003eThis tool is suited for internal threading operations in small-bore components found in precision machining environments including aerospace, medical device, and general manufacturing applications. The 0.1181-inch shank diameter matches the threading diameter, allowing it to enter tight bores. The 0.01-inch projection from edge and 0.0118-inch projection from center allow controlled engagement in restricted clearance situations. Right-hand thread direction is standard for the majority of conventional threading setups encountered in production machining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and dimensional stability in small-diameter threading\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for elevated heat resistance and extended tool life in dry or minimal-coolant conditions\u003c\/li\u003e\n  \u003cli\u003e60-degree profile angle covers unified and metric fine-pitch thread forms\u003c\/li\u003e\n  \u003cli\u003e36 to 48 TPI range targets fine-pitch internal threads in small-bore work\u003c\/li\u003e\n  \u003cli\u003e0.1181-inch minimum threading diameter suits micro and miniature component applications\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design; compatible with external coolant delivery setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide threading tool for internal right-hand thread applications requiring a 60-degree profile, 36 to 48 TPI range, and a minimum bore diameter of 0.1181 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this tool should be performed by a qualified machinist familiar with CNC or manual threading operations. Ensure the machine spindle and toolholder are powered down and locked out before mounting or removing the tool. Verify shank-to-holder concentricity and runout before engaging the workpiece, as small-diameter carbide tooling is sensitive to misalignment and prone to fracture under lateral load. Do not exceed the recommended depth of cut for the workpiece material, and confirm thread direction programming matches the right-hand designation of this tool before initiating a threading cycle.\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: 0.1181 inches (3.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Threads Per Inch\u003c\/strong\u003e: 36 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Threads Per Inch\u003c\/strong\u003e: 48 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1181 inches (3.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.8661 inches (22.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection from Edge\u003c\/strong\u003e: 0.01 inches (0.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection from Center\u003c\/strong\u003e: 0.0118 inches (0.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlat Width\u003c\/strong\u003e: 0.002 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: TiAlN\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: 0.025 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6403941\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51743291474226,"sku":"6403941","price":81.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79f25b46f58ddf61fad3b6d9b7276006.jpg?v=1788845170","url":"https:\/\/voomisupply.com\/products\/iscar-6403941-single-point-threading-tool-internal-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
