It cuts right hand and is designed to hold tight tolerances in small-diameter bores. The 3\/16-inch shank diameter and 2-inch overall length make it well suited for short-run and production boring where rigidity and dimensional accuracy are critical. The uncoated carbide surface supports a wide range of cutting fluids and is compatible with standard carbide-grade insert geometries. Machinists working on CNC lathes and manual turning centers will find the geometry straightforward to set up and qualify.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for applications requiring a minimum bore diameter of 0.185 inches and a maximum bore depth of 1.25 inches. It is a practical choice for internal diameter finishing, shoulder boring, and light roughing passes in ferrous and non-ferrous materials on CNC turning centers and manual lathes. The radial relief geometry reduces interference in tight bore entries and helps maintain surface finish at depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for high rigidity and wear resistance in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eRadial relief geometry minimizes clearance interference at bore entry\u003c\/li\u003e\n  \u003cli\u003eRight hand cutting direction for standard CNC and manual lathe setups\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.185 inches enables work in very small internal diameters\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 1.25 inches with a compact 2-inch overall length\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional accuracy without coating thickness variables\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit boring bar for CNC turning centers and manual lathes that accept a 3\/16-inch shank diameter tool holder, where right hand internal boring operations are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist. Secure the shank firmly in a compatible boring bar holder, ensuring minimum overhang beyond the holder to reduce chatter. Power down and lock out the spindle before changing or adjusting tooling. Verify bore alignment and runout before engaging the cut to protect both the tool and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Radial Relief\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.185 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 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\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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BB1812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51971912597810,"sku":"BB1812","price":39.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88c997d7fd1ac86aed975af74c47e079.jpg?v=1789959054","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-bb1812-radial-relief-boring-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
