Machined from submicron-grade solid carbide, this bar delivers the rigidity and wear resistance required for tight-tolerance work in steel, stainless, cast iron, and non-ferrous materials. The right-hand cutting direction suits standard CNC and manual lathe setups. It accepts a minimum bore diameter of 0.185 inches and a maximum bore depth of 0.5 inches, making it well suited for shallow, close-tolerance bores where rigidity and tool deflection are critical concerns. The uncoated carbide surface is ready to run as delivered.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is used in precision machining environments including tool rooms, production shops, and job shops running CNC lathes or manual engine lathes. Its 3\/16-inch shank diameter fits standard small-bore toolholders and quick-change systems designed for that shank size. Typical applications include finishing internal diameters, cleaning up drilled holes, and producing close-tolerance bores in small workpieces or miniature components. It is installed by machinists and CNC operators working to blueprint tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRadial relief geometry reduces cutting forces on small-diameter bores\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide construction for superior rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.185 inches for tight internal features\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 0.5 inches suitable for shallow through and blind bores\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut for standard lathe rotation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no additional prep required before use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit toolholders accepting a 3\/16-inch shank diameter.

Power down and lock out the machine spindle before mounting or removing the boring bar. Ensure the shank is fully seated and clamped securely in the toolholder to minimize overhang and reduce deflection. Verify bore alignment and starting diameter before beginning the cut to avoid tool breakage on this small-diameter bar.\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 0.5 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\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: BB184\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52101430051122,"sku":"BB184","price":39.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97c68c564517cf9baa097e255868e7b8.jpg?v=1790069767","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-bb184-radial-relief-boring-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
