Machined from submicron-grade solid carbide, it delivers consistent rigidity and wear resistance at small diameters where high-speed steel tooling typically falls short. The bar handles a minimum bore diameter of 0.12 inches and reaches a maximum bore depth of 0.625 inches, making it well suited for shallow, fine-tolerance bores. With a bright finish coating and a 0.125-inch shank diameter, it mounts directly into standard tool holders used on CNC lathes and machining centers. A right-hand cutting direction is standard for conventional spindle rotation setups.\u003c\/p\u003e\u003cp\u003eThis boring bar fits residential and commercial machine shop environments where small-diameter internal features require consistent surface finish and dimensional accuracy. It is used on CNC turning centers, manual lathes, and mill-turn machines running production or prototype work. The submicron carbide grade performs well in ferrous and non-ferrous materials where chatter resistance and edge retention are priorities. Machinists and tool-and-die professionals working on small components, hydraulic bodies, or precision instrument housings will find this bar a direct fit for fine-bore finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for superior rigidity and edge retention at small diameters\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.12 inches for tight internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.625 inches suits shallow precision bores\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard spindle rotation\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 common small-bore tool holders and collet chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 0.125-inch bore tool holders and collet systems on CNC lathes, turning centers, and machining centers configured for right-hand internal boring operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine in a full stop and all axes locked. Secure the shank firmly in a compatible collet or tool holder to the holder manufacturer's specified clamping procedure before running. Confirm cutting direction and spindle rotation match before initiating a cut. Machinists should verify bore depth clearance against the maximum bore depth specification before programming depth passes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.625 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-HB120625\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755720245554,"sku":"ACC-HB120625","price":42.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4e1f8b5ee0b2ae18b387984d786bba8.jpg?v=1788958560","url":"https:\/\/voomisupply.com\/products\/accupro-acc-hb120625-helical-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
