With a minimum bore diameter of 0.268 inches and a maximum bore depth of 1.181 inches, this bar handles tight-bore finish work where rigidity and precision matter. The TN35 grade designation indicates a titanium nitride finish coating, which improves wear resistance and extends tool life in ferrous and non-ferrous materials. At 1.378 inches overall length and a 0.008 inch corner radius, this tool is suited for close-tolerance internal contour work. Machinists and toolroom technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for precision internal profiling in production and toolroom environments. It fits turning centers and CNC lathes that accept a 5.20 mm shank. The right-hand cutting direction suits standard spindle rotation for most horizontal turning setups. Applications include finish boring of small-diameter bores in steel, cast iron, and non-ferrous alloys where surface finish and dimensional accuracy are the primary requirements. The compact overall length makes it well-suited to short-reach, small-bore applications where larger tooling cannot reach or maintain rigidity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high rigidity and vibration resistance in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TN35 grade) coating for improved wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.268 inches enables work in tight internal features\u003c\/li\u003e\n  \u003cli\u003e0.008 inch corner radius supports controlled internal profile contours\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation for standard CNC lathe setups\u003c\/li\u003e\n  \u003cli\u003e5.20 mm shank diameter and 35.00 mm overall length for compact tool station fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC lathes and turning centers that accept a 5.20 mm round shank boring bar.

Ensure the shank is properly seated and clamped in the toolholder to the manufacturer-specified engagement depth before running. Verify bore diameter and depth clearance before cycling the spindle. Do not exceed the tool's rated minimum bore diameter, as contact with the bore wall can cause tool breakage in solid carbide tooling.\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: 0.268 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.181 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.378 inches (35.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.008 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: Titanium Nitride\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: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: R105184057 TN35\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HORN","offers":[{"title":"Default Title","offer_id":67911964819762,"sku":"R105184057 TN35","price":137.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46e62a787b064b744d8290878dcf5a1a.jpg?v=1791223577","url":"https:\/\/voomisupply.com\/products\/horn-r105184057-tn35-profile-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
