It is designed for small-diameter internal boring operations where rigidity and dimensional precision are critical. With a minimum bore diameter of 0.06 inches and a maximum bore depth of 0.4 inches, this bar handles tight, shallow bores that standard tooling cannot reach. The 1\/8-inch shank diameter and 1.5-inch overall length make it well suited for Swiss-style, screw machine, and small CNC lathe applications. The bright finish coating leaves the carbide substrate exposed for visual inspection and minimal friction at the cutting edge.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in precision machining environments where bore diameters in the 0.06-inch range must be held to close tolerances. Typical applications include medical component machining, watch and instrument parts, hydraulic valve bodies, and other small-bore work performed on CNC lathes or manual precision lathes. The left-hand cutting direction suits specific tool orientation and spindle configurations where a right-hand bar would interfere or produce unfavorable chip flow.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high rigidity and wear resistance in small-bore applications\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.06 inches enables work on very small internal diameters\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.4 inches suited to shallow internal features\u003c\/li\u003e\n\u003cli\u003eLeft-hand cut direction for specific spindle and tool-post orientations\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits standard small-bore tool holders and collet blocks\u003c\/li\u003e\n\u003cli\u003eBright finish coating preserves carbide surface integrity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for CNC lathes, Swiss-type screw machines, and manual precision lathes equipped with 1\/8-inch bore tool holders accepting left-hand boring bars.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before securing the bar in the tool holder. Ensure the shank is clamped with adequate contact length to minimize overhang deflection given the small diameter. Follow the machine tool manufacturer's guidelines for tool holder torque and runout verification before beginning 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: 0.06 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 (1\/8 inch)\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-BBL060400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731744325938,"sku":"ACC-BBL060400","price":41.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bbf18fb60fc23aef4563470aa95b10f_5cd2f6b0-6079-4635-8511-0cbdbb7da193.jpg?v=1788734463","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl060400-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
