Manufactured from submicron-grade carbide with a bright finish coating, it delivers tight dimensional control in small-bore applications. The left-hand cutting direction suits specific tooling orientations and back-boring setups. With a minimum bore diameter of 0.08 inches and a maximum bore depth of 0.4 inches, this bar is built for fine, close-tolerance work in hard and abrasive materials. Machinists and tool-and-die professionals working on small-diameter features rely on submicron carbide to maintain edge integrity at tight tolerances.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for small-bore finish and semi-finish operations in job shop, production, and tool room environments. The 1\/8-inch shank diameter and 1.5-inch overall length make it appropriate for compact toolholders and turret setups where clearance is limited. Left-hand cut geometry is typically selected for reverse-spindle operations, back-boring, or specific machine configurations that require cutting in the opposite direction from a standard right-hand bar. It is intended for use by machinists in metalworking, aerospace, medical device, and precision parts applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for edge stability in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting direction for reverse-spindle and back-boring applications\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.08 inches enables fine small-hole work\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.4 inches suits shallow precision features\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces friction and aids chip evacuation\u003c\/li\u003e\n\u003cli\u003eCompact 1\/8-inch shank fits standard small-bore toolholders and turrets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use boring bar for standard 1\/8-inch shank toolholders used in CNC lathes, manual lathes, and machining centers requiring left-hand cut solid carbide boring tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before mounting or adjusting the boring bar in the toolholder. Secure the shank firmly in a properly sized 1\/8-inch bore toolholder to the toolholder manufacturer's recommended clamping procedure. Verify cutting direction and spindle rotation match the left-hand geometry 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: 0.08 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: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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-BBL080400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727174533426,"sku":"ACC-BBL080400","price":41.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab0a2d463dee9666d0668ef203c2669c.jpg?v=1788674325","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl080400-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
