Built with a TiN (titanium nitride) finish coating and a TN35 grade carbide substrate, this tool handles tight-tolerance bores in a compact package. The minimum bore diameter is 0.079 inches, the maximum bore depth reaches 0.236 inches, and the corner radius is 0.006 inches. At 1.1811 inches overall length with a 1\/16-inch shank diameter, this bar fits collet-style and small-bore toolholding systems used in precision machining environments.\u003c\/p\u003e\n\u003cp\u003eThis profile boring bar is suited for precision internal profiling, grooving, and contouring in small-bore workpieces across production and job-shop settings. The right-hand cutting direction makes it compatible with conventional CNC lathe spindle rotation. It is typically installed by machinists and tool-and-die professionals working with aluminum, steel, stainless, and non-ferrous alloys where bore geometry and surface finish are closely controlled. Applications include watchmaking components, medical device parts, and any small-diameter bore requiring a defined corner radius and controlled depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in small-bore profiling\u003c\/li\u003e\n  \u003cli\u003eTiN finish coating (TN35 grade) for improved surface hardness and tool life\u003c\/li\u003e\n  \u003cli\u003e0.079 inches minimum bore diameter enables access to very small internal features\u003c\/li\u003e\n  \u003cli\u003e0.006 inches corner radius for controlled profile geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, compatible with standard CNC lathe spindle rotation\u003c\/li\u003e\n  \u003cli\u003eCompact 1.1811 inches overall length with 1\/16-inch shank for collet-style toolholding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use profile boring bar for CNC lathes and machining centers equipped with collet-style or small-shank toolholding systems accepting a 1\/16-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists following shop safety procedures. Power down and lock out the spindle before seating or removing tooling. Ensure the shank is fully engaged in the collet or toolholder and that runout is verified before cutting. Follow machine manufacturer torque guidelines when tightening collet nuts; do not overtighten on carbide shanks.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Profile Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.079 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.236 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.1811 inches (30.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.006 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TN35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: R105180902 TN35\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HORN","offers":[{"title":"Default Title","offer_id":67905953825074,"sku":"R105180902 TN35","price":97.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7b433b9f4c151bf5e44e8743829b677.jpg?v=1791160761","url":"https:\/\/voomisupply.com\/products\/horn-r105180902-tn35-profile-boring-bar-solid-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
