It features a 60-degree profile angle and handles thread pitches from 18 to 27 threads per inch (TPI), making it suitable for a range of standard unified and metric-equivalent thread forms. The insert cuts to a depth of 0.591 inches and has an overall length of 1.181 inches. With a minimum threading diameter of 0.236 inches, it is suited for small-bore internal threading work. Both left-hand and right-hand thread directions are supported. The insert weighs approximately 0.025 pounds.\u003c\/p\u003e\u003cp\u003eThis threading insert is used in precision machining environments including job shops, production turning facilities, and maintenance shops where internal thread generation is required. It is typically installed in a compatible HORN toolholder system. The small minimum bore diameter and controlled projection from center of 0.130 inches make it well suited for tight-clearance internal threading applications in ferrous and non-ferrous materials. Machinists working with fine-pitch threads in the 18-27 TPI range will find the 60-degree profile appropriate for unified thread standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e60-degree profile angle for unified and standard thread forms\u003c\/li\u003e\n\u003cli\u003eInternal thread cutting with support for both left-hand and right-hand thread directions\u003c\/li\u003e\n\u003cli\u003eThreading range of 18 to 27 TPI\u003c\/li\u003e\n\u003cli\u003eMinimum threading diameter of 0.236 inches for small-bore applications\u003c\/li\u003e\n\u003cli\u003eCutting depth of 0.591 inches\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 1.181 inches with 0.130 inches projection from center\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with compatible HORN toolholder systems that accept the R105NP1826 TN35 insert geometry for internal single point threading operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the toolholder manufacturer guidelines for insert seating and clamping torque. Ensure the machine spindle is fully stopped and the toolholder is secured before installing or replacing the insert. Verify thread direction setting on the machine control matches the insert orientation before initiating a threading cycle. Follow standard shop safety practices when handling carbide inserts due to sharp cutting edges.\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\u003eProfile Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand and Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Threading Diameter\u003c\/strong\u003e: 0.236 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: 27 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 0.591 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.181 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection From Center\u003c\/strong\u003e: 0.130 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: HORN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R105NP1826 TN35\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HORN","offers":[{"title":"Default Title","offer_id":67905990426930,"sku":"R105NP1826 TN35","price":121.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/567c81d81317d738706469d6a024d270.jpg?v=1791161724","url":"https:\/\/voomisupply.com\/products\/horn-r105np1826-tn35-threading-insert-60-degree-internal","provider":"Voomi Supply","version":"1.0","type":"link"}
