Built from solid carbide with an AlTiN+ coating, the tool handles thread pitches from 16 to 40 TPI using a 60-degree profile angle. The 0.2-inch minimum threading diameter and 0.4-inch cutting depth make it suited for small-bore internal threading work where rigidity and edge retention are critical. The AlTiN+ finish provides heat and wear resistance, extending tool life during dry or semi-dry cutting conditions. Machinists and CNC operators working in production or job-shop environments rely on this tool for consistent thread form in tight-tolerance bores.\u003c\/p\u003e\u003cp\u003eThis tool is configured for internal threading applications across a range of materials commonly encountered in precision machining, including steel, stainless steel, and cast iron. The 1\/4-inch shank diameter fits standard boring bar holders and quick-change tooling systems. With a 2.5-inch overall length and 0.045-inch projection from the edge, it is well suited for threading shallow to moderate-depth bores in residential and commercial component manufacturing environments. No coolant-through capability is present, so chip evacuation management is the responsibility of the operator based on material and depth of cut.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in internal threading\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating for improved heat resistance and wear performance during dry cutting\u003c\/li\u003e\n\u003cli\u003e16 to 40 TPI range with a 60-degree profile angle for unified thread forms\u003c\/li\u003e\n\u003cli\u003e0.2-inch minimum threading diameter for small-bore internal applications\u003c\/li\u003e\n\u003cli\u003e0.4-inch cutting depth with 0.045-inch projection from edge for controlled engagement\u003c\/li\u003e\n\u003cli\u003e1\/4-inch shank diameter compatible with standard CNC tooling holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style single point threading tool for use in CNC lathes and turning centers equipped with 1\/4-inch shank toolholders supporting internal threading operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before mounting or removing the tool from the holder. Ensure the shank is seated fully and clamped securely in the toolholder before operation. Verify thread pitch and profile settings in the machine control before initiating a threading pass.\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: 0.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Threads Per Inch\u003c\/strong\u003e: 16 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Threads Per Inch\u003c\/strong\u003e: 40 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection from Edge\u003c\/strong\u003e: 0.045 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\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN+\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: TT200400A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51972017586482,"sku":"TT200400A","price":65.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5905742ea790e111d1eae978cd278ac4.jpg?v=1789961109","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tt200400a-threading-tool-16-40-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
