Built from submicron-grade carbide with a bright finish coating, it delivers consistent cutting performance in tight bores. The left-hand cutting direction suits specific machine setups where conventional right-hand tooling cannot be used. With a minimum bore diameter of 0.05 inches and a maximum bore depth of 0.4 inches, this bar targets fine, shallow bores where rigidity and dimensional accuracy are critical. Machinists and tool-and-die professionals working on CNC lathes and boring mills are the primary users of this style of tooling.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for small-bore finishing and semi-finishing passes in ferrous and non-ferrous materials on CNC or manual lathes. The 1\/8-inch shank diameter fits standard small-bore tool holders and quick-change systems commonly found in precision machining environments. It is appropriate for shops producing medical components, instrument parts, watch components, or other fine-tolerance work requiring controlled bore geometry at diameters starting at 0.05 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for rigidity and wear resistance in small-bore applications\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting direction for reverse-spindle or back-boring setups\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.05 inches suits very fine internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.4 inches for shallow through and blind bore work\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces built-up edge in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits standard small-bore tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct addition for small-bore internal turning setups using 1\/8-inch shank tool holders on CNC or manual lathes requiring left-hand cut boring bars.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of boring bars should be performed by a qualified machinist following the machine tool manufacturer guidelines. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and clamped securely in the tool holder to minimize runout and chatter. Do not exceed the recommended overhang for the shank diameter, as excessive overhang increases deflection and reduces bore accuracy.\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: 0.05 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-BBL050400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728899670322,"sku":"ACC-BBL050400","price":40.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d63a8479e547c839fe0094c9f01f9e4b.jpg?v=1788697523","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bbl050400-boring-bar-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
