With a minimum bore diameter of 0.0620 inches and a maximum bore depth of 0.1870 inches, this bar is built for tight-tolerance small-bore work in CNC lathes and manual turning centers. The 3.95 mm shank diameter provides a compact, rigid setup for accessing small-diameter bores. The uncoated solid carbide construction delivers consistent cutting performance in a range of workpiece materials. Machinists and tool-and-die professionals rely on this style of bar for high-precision finishing passes where dimensional accuracy is critical.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for small-bore internal machining applications in production and job-shop environments. The right-hand cut orientation makes it compatible with standard spindle rotation on conventional CNC turning setups. Its compact geometry is well suited for watchmaking components, medical device parts, hydraulic fittings, and other precision small-diameter bores where clearance is limited and surface finish requirements are tight.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimum bore diameter of 0.0620 inches for small-bore access\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.1870 inches for shallow to moderate reach\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eUncoated grade suitable for a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard CNC lathe setups\u003c\/li\u003e\n\u003cli\u003e3.95 mm shank diameter for compact tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit boring bar for CNC lathes and turning centers equipped with tooling systems accepting a 3.95 mm shank diameter in right-hand boring bar configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist with the machine powered down and in a locked-out state before tooling changes. Ensure the shank is properly seated and clamped in the tool holder to the tool holder manufacturer's specified clamping torque. Confirm bore diameter and depth clearances against the workpiece setup before initiating a cutting pass. Follow applicable shop safety protocols and machine manufacturer guidelines during tool changes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.0620 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.1870 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.95 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1256313\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730255249714,"sku":"1256313","price":159.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43abf70473250f442736e422e5e152b9.jpg?v=1788714190","url":"https:\/\/voomisupply.com\/products\/kennametal-1256313-boring-bar-solid-carbide-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
