Built from submicron solid carbide with a bright finish coating, this right-hand cut tool delivers tight tolerances in small-bore applications. It accepts a minimum bore diameter of 0.12 inches and reaches a maximum bore depth of 0.35 inches, making it suited for shallow, fine-finish internal cuts. The 3\/16-inch shank diameter and 2-inch overall length give it a compact, rigid profile. Corner radius range runs from 0.005 to 0.008 inches, allowing controlled edge preparation on precision components. Machinists and tooling specialists use this bar in CNC and manual turning or boring applications where dimensional accuracy is critical.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for small-bore finish and semi-finish operations in ferrous and non-ferrous materials. Its submicron carbide construction supports use in high-speed applications where tool wear resistance and dimensional stability matter. The bright (uncoated) finish is appropriate for non-ferrous materials such as aluminum, brass, and copper, as well as certain plastics. It is sold individually and is a direct stock item for tooling rooms, job shops, and production machining environments requiring consistent small-bore geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for wear resistance and rigidity in small-bore cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard boring bar setups\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.12 inches for tight internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.35 inches\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.005 to 0.008 inches for precise edge geometry\u003c\/li\u003e\n\u003cli\u003eBright finish coating suited for non-ferrous and non-coated applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit boring bar for toolholders and boring heads accepting a 3\/16-inch round shank diameter in CNC turning centers, manual lathes, and boring mills requiring right-hand internal cutting tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Secure the shank firmly in the toolholder to the full recommended engagement depth to minimize overhang and chatter. Ensure the machine spindle is fully stopped and the control is in a safe state before mounting or removing the tool. Follow shop safety protocols and machine manufacturer guidelines for tool clamping torque and runout verification before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Corner Radius\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: 0.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.005 to 0.008 inches\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: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B120350R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746297610546,"sku":"B120350R","price":58.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b170fde506c002ae9043e5a88775e885.jpg?v=1788868097","url":"https:\/\/voomisupply.com\/products\/accupro-b120350r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
