Constructed from submicron solid carbide, this bar delivers the rigidity and wear resistance required for consistent, repeatable cuts at small diameters. It features a right-hand cutting direction and an uncoated finish, making it well suited to ferrous and non-ferrous materials where coating buildup is a concern. With a minimum bore diameter of 0.373 inches and a 3\/8-inch shank diameter, this tool fits standard boring head and toolholder setups common in production and job-shop environments. Machinists and toolroom operators select this bar when surface finish and dimensional accuracy inside bores are critical.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is used in CNC lathes, machining centers, and manual lathes where small-diameter internal turning is required. Its 2-inch overall length and 0.5-inch maximum bore depth suit shallow-bore operations typical in component manufacturing, mold work, and precision fixture production. The radial relief geometry reduces tool pressure and helps maintain bore geometry in both interrupted and continuous cutting conditions. It is appropriate for light-duty finish boring passes where carbide rigidity is needed to minimize deflection at small diameters.\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\u003c\/li\u003e\n  \u003cli\u003eRadial relief geometry reduces cutting pressure and supports accurate bore geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard boring operations\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.373 inches suits tight internal diameter work\u003c\/li\u003e\n  \u003cli\u003eUncoated finish for compatibility with a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter fits widely available boring head toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit boring bar for toolholders and boring heads accepting a 3\/8-inch shank diameter in CNC and manual lathe setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist with the machine powered down and the spindle locked before securing the bar in the toolholder. Ensure the shank is fully engaged in the holder and properly torqued per the toolholder manufacturer specifications before initiating a cut. Confirm bore depth does not exceed the 0.5-inch maximum to prevent tool deflection or breakage. Handle carbide tooling carefully to avoid chipping the cutting edge during setup.\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: 0.373 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: 0.375 inches (3\/8 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: 0.125 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: BB374\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52016452075826,"sku":"BB374","price":77.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4404809f83d41ff94ff19c1477b0b5f.jpg?v=1790008689","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-bb374-radial-relief-boring-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
