It accepts a minimum bore diameter of 0.160 inches and reaches a maximum bore depth of 0.400 inches, making it suited for tight, shallow bores in hardened or abrasive workpiece materials. The 3\/16-inch shank diameter and 2-inch overall length make this a compact tool intended for small-bore work on CNC lathes, boring mills, and manual turning centers. Machinists and toolroom operators select submicron carbide grade for its fine grain structure, which supports sharp cutting edges and consistent tool life in demanding materials.\u003c\/p\u003e\u003cp\u003eThis boring bar is designed for internal diameter finishing and semi-finishing operations where bore size control and surface finish are critical. The left-hand cutting direction suits applications where spindle rotation or toolholder orientation requires a climb-cut configuration. Typical use cases include precision bores in aerospace components, hydraulic valve bodies, medical parts, and general machining where bore tolerances are tight and standard high-speed steel tooling lacks the rigidity or wear resistance required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction provides high rigidity and superior wear resistance compared to standard carbide grades\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.160 inches enables access to small, tight bores\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.400 inches suitable for shallow precision boring passes\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting direction for specific toolholder and spindle orientation requirements\u003c\/li\u003e\n\u003cli\u003e3\/16-inch shank diameter fits standard small-bore toolholders and boring heads\u003c\/li\u003e\n\u003cli\u003eCompact 2-inch overall length reduces overhang and supports chatter-free cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders and boring heads accepting a 3\/16-inch round shank. Verify toolholder bore diameter and clamping style before installation to confirm fitment for your specific machine setup.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard lathe or machining center lockout procedures before mounting or adjusting tooling. Secure the shank fully within the toolholder to the recommended engagement depth and confirm runout with a dial indicator before cutting. Avoid cantilevering the bar beyond the rated maximum bore depth, as excess overhang with small-diameter carbide bars increases breakage risk. Refer to the machine tool and toolholder manufacturer guidelines for proper torque and clamping procedures.\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: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.160 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 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\u003eWeight\u003c\/strong\u003e: 0.0625 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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-BBL160400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755628527922,"sku":"ACC-BBL160400","price":42.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1042a6d15f66e016d76d0f93749bacf1.jpg?v=1788957222","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl160400-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
