Coated with titanium nitride (TiN), this insert delivers improved wear resistance and extended tool life across a wide range of workpiece materials. It carries a positive rake geometry with an 8-degree rake angle and an 18-degree relief angle, reducing cutting forces and minimizing heat buildup at the cutting edge. The 0.20 mm corner radius produces a fine surface finish on bored features. Screw-clamped mounting ensures secure, repeatable seating in compatible toolholders. Weighing approximately 0.1 pounds, the insert measures 10.70 mm in length, 8.00 mm in width, and 3.95 mm in thickness.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for boring, profiling, and undercut operations in both light and medium-duty applications. It is classified as a universal-grade insert, rated for workpiece material codes K, M, N, P, and S, covering cast iron, stainless steel, non-ferrous materials, steel, and heat-resistant superalloys. The maximum depth of cut is 0.0910 inches. The right-hand cutting orientation and positive rake make it a practical choice for finish boring passes where dimensional accuracy and surface quality are critical. Licensed machinists and CNC setup technicians typically specify this insert for tight-tolerance internal diameter work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiN coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry (8-degree rake angle) reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003e18-degree relief angle suits finish boring and profile work\u003c\/li\u003e\n  \u003cli\u003e0.20 mm corner radius for fine surface finish on internal diameters\u003c\/li\u003e\n  \u003cli\u003eScrew-clamped insert holding for secure, repeatable positioning\u003c\/li\u003e\n  \u003cli\u003eUniversal primary workpiece material rating covering K, M, N, P, and S codes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in HORN R111 series boring toolholders that accept screw-clamped inserts of this geometry and size. Verify toolholder pocket dimensions against insert length of 10.70 mm, width of 8.00 mm, and thickness of 3.95 mm before ordering.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key to tighten the clamping screw to the toolholder manufacturer specification  -  do not overtighten, as carbide inserts can crack under excessive clamp force. Inspect the insert pocket for chips or debris before seating the insert to ensure full, flat contact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Series\u003c\/strong\u003e: R111\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1867.02\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TN35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 8 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 18 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 10.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.95 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0910 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: K, M, N, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 509\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.1 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: HORN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R111186702 TN35\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HORN","offers":[{"title":"Default Title","offer_id":67909331517746,"sku":"R111186702 TN35","price":70.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76a2b6354725c5e7f98e2f361fcdece2.jpg?v=1791186398","url":"https:\/\/voomisupply.com\/products\/horn-r111186702-tn35-boring-insert-solid-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
