Built from fine grain solid carbide with a Nano-A finish coating, it delivers consistent cutting performance in tight-tolerance bores. The bar accepts a 6 mm shank diameter, reaches a minimum bore diameter of 5.7 mm, and handles a maximum bore depth of 42 mm. With an overall length of 67 mm and a 0.2 mm corner radius, it suits precision finishing passes where dimensional accuracy and surface finish are critical. Machinists and tooling specialists working in production or job-shop environments will find this bar well suited to small-diameter internal profile work.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for small-bore internal turning and profiling applications in metalworking operations. Its right-hand cutting direction makes it compatible with standard spindle rotation on conventional CNC turning setups. The fine grain carbide substrate and Nano-A coating support use in ferrous and non-ferrous materials where edge retention and wear resistance matter. It is suited to both production runs and prototype work requiring precise bore geometry and controlled corner radii.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFine grain solid carbide construction for improved edge retention and rigidity in small-diameter bores\u003c\/li\u003e\n  \u003cli\u003eNano-A finish coating for enhanced wear resistance and reduced friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e0.2 mm corner radius for accurate profile and finishing passes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC lathe spindle rotation\u003c\/li\u003e\n  \u003cli\u003e6 mm shank diameter with 67 mm overall length for stable toolholder engagement\u003c\/li\u003e\n  \u003cli\u003eHandles bore depths up to 42 mm from a minimum entry diameter of 5.7 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide boring bar for use in standard 6 mm boring bar toolholders on CNC lathes and turning centers performing small-bore internal profiling operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Secure the shank fully within the toolholder to the manufacturer-recommended clamping depth before beginning any cut. Ensure the machine spindle is fully stopped and the control is in an e-stop or safe state before mounting or removing the bar. Follow your facility safety procedures and machine tool builder guidelines for toolholder torque and runout verification prior to first use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 5.7 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 42 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 67 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.2 mm\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\u003eMaterial Grade\u003c\/strong\u003e: Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Nano-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 2.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 0.16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9257100060430\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734740992306,"sku":"9257100060430","price":84.39,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff4652912cc90b28f5f1f5223e33bd20.jpg?v=1788766432","url":"https:\/\/voomisupply.com\/products\/guhring-9257100060430-profile-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
