Built from submicron-grade carbide with a bright finish, it delivers consistent cutting performance in tight-tolerance bore applications. The bar features a right-hand cutting direction, a minimum bore diameter of 0.14 inches, and a maximum bore depth of 0.4 inches. The 3\/16-inch shank diameter and 2-inch overall length make this a compact tool suited for small-diameter bore work where rigidity and dimensional accuracy are critical. Machinists and toolroom operators working with small bores will find this bar well suited to production and repair applications.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in precision machining environments including job shops, toolrooms, and production facilities. It is suited for boring operations in ferrous and non-ferrous materials where a small minimum bore diameter is required. The right-hand cutting direction is the standard orientation for conventional lathe setups. Its compact overall length of 2 inches supports use in close-clearance setups and on smaller CNC turning centers or manual lathes where toolpost space is limited.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for improved wear resistance and cutting edge stability\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.14 inches for small-bore applications\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.4 inches\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe orientation\u003c\/li\u003e\n\u003cli\u003e3\/16-inch shank diameter for compatibility with small boring bar holders\u003c\/li\u003e\n\u003cli\u003eBright finish coating with no additional surface treatment interference\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard right-hand boring bar for use in tool holders accepting a 3\/16-inch round shank, compatible with conventional and CNC lathes configured for small-diameter internal boring.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolroom practices. Ensure the machine spindle is fully stopped and the machine is powered down before mounting or removing tooling. The bar should be secured firmly in the tool holder with minimal overhang beyond the holder to maximize rigidity and reduce chatter. Refer to the machine manufacturer guidelines and applicable shop safety procedures when setting cutting parameters.\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: 0.14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.4 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: 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: ACC-BB140400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727323595058,"sku":"ACC-BB140400","price":51.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3efc94e9117a835bf328156db4c2ee54.jpg?v=1788676317","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb140400-boring-bar-submicron-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
