Manufactured from submicron-grade solid carbide with a bright finish coating, this bar delivers tight dimensional accuracy and excellent surface finish in a wide range of workpiece materials. It accepts a 3\/8-inch shank diameter and reaches a maximum bore depth of 3 inches, with a minimum bore diameter of 0.36 inches. Overall length is 4 inches. Machinists and toolroom professionals use this bar where right-hand tooling is not suited to the setup orientation.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for small-diameter internal turning applications in production and job-shop environments. The left-hand cutting direction makes it appropriate for back-boring operations or setups where the spindle rotation and tool approach require a left-hand orientation. The submicron carbide grade provides wear resistance in both ferrous and non-ferrous materials, supporting consistent tool life across repeated passes at moderate to high cutting speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for enhanced wear resistance and rigidity\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting direction for back-boring and non-standard spindle orientations\u003c\/li\u003e\n\u003cli\u003e0.36-inch minimum bore diameter supports small internal features\u003c\/li\u003e\n\u003cli\u003e3-inch maximum bore depth for reaching deeper bores without extended tooling setups\u003c\/li\u003e\n\u003cli\u003eBright finish coating — no additional surface treatment required\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank diameter for compatibility with standard boring bar holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8-inch boring bar tool holders on CNC and manual turning centers where left-hand internal boring tooling is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before securing or removing tooling. Ensure the shank is fully seated and clamped to the minimum insertion depth specified by the tool holder manufacturer to prevent deflection. Verify cutting direction and spindle rotation match before initiating a cut.\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: 0.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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: 0.25 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-BBL3603000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729296589106,"sku":"ACC-BBL3603000","price":104.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/048a291339f1806b89d32be64705ed5e.jpg?v=1788702578","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl3603000-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
