It carries a 60-degree profile angle and handles a threading diameter range starting at 0.236 inches. The insert covers 18 to 27 threads per inch (TPI) and delivers a cutting depth of 0.591 inches. Overall length is 1.181 inches with a projection from center of 0.130 inches. This insert is suited for use in CNC turning centers and manual lathes where precise internal thread forms are required. Machinists and toolroom professionals install this type of insert into compatible HORN toolholders for high-repeatability threading passes.\u003c\/p\u003e\u003cp\u003eThis insert is applied in internal threading applications on both left-hand and right-hand thread directions, giving it broad versatility across common thread forms. The 60-degree profile angle makes it compatible with standard unified and metric thread forms of that included angle. Typical use cases include threading bores in hydraulic components, fittings, and machined housings where thread quality and dimensional accuracy are critical. The insert is packaged individually and is sold with a minimum order quantity of 2 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e60-degree profile angle for standard internal thread forms\u003c\/li\u003e\n\u003cli\u003eCovers 18 to 27 TPI range in a single insert geometry\u003c\/li\u003e\n\u003cli\u003eSupports both left-hand and right-hand thread directions\u003c\/li\u003e\n\u003cli\u003e0.591 inches cutting depth accommodates typical bore threading requirements\u003c\/li\u003e\n\u003cli\u003eCompact 1.181 inches overall length suits tight toolholder setups\u003c\/li\u003e\n\u003cli\u003e0.130 inches projection from center for consistent insert positioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for use in HORN single point internal threading toolholder systems that accept the R105 insert seat geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed by a machinist or toolroom technician into a compatible HORN toolholder. Ensure the machine spindle is fully stopped and the tool turret is in a safe index position before changing inserts. Use the correct torque wrench per the toolholder manufacturer's clamping specifications and inspect the insert seat for chips or debris before seating the insert. Verify thread form and pitch with a calibrated thread gauge after the first pass before completing the full threading cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eCutting Depth\u003c\/strong\u003e: 0.591 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\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\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\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: R105NP2726 TN35\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HORN","offers":[{"title":"Default Title","offer_id":67913379447090,"sku":"R105NP2726 TN35","price":126.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_531088f0-80b6-46dd-9553-f3d9686c1244.jpg?v=1791244911","url":"https:\/\/voomisupply.com\/products\/horn-r105np2726-tn35-threading-insert-18-27-tpi-internal","provider":"Voomi Supply","version":"1.0","type":"link"}
