It accepts a minimum bore diameter of 0.48 inches and reaches a maximum bore depth of 3 inches, making it suited for a range of short to medium-depth internal features. The 0.5-inch shank diameter provides a secure, rigid grip in standard boring bar holders, and the bright finish reduces built-up edge in many common workpiece materials. Overall length is 4 inches. Licensed machinists and toolroom operators are the primary installers and users.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is used in precision machining environments including job shops, production floors, and toolrooms. Its right-hand cutting direction matches the standard spindle rotation of most CNC turning centers and manual lathes. The helical geometry promotes efficient chip evacuation during internal boring passes, which is especially useful when working in blind holes or deeper bores where chip packing can be a concern. It is appropriate for use on ferrous and non-ferrous workpieces where tight bore tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eHelical flute geometry promotes chip flow out of the bore during cutting\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.48 inches suits small to mid-range internal features\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 3 inches covers short to medium-depth internal passes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut matches standard spindle rotation on most turning equipment\u003c\/li\u003e\n  \u003cli\u003eBright finish reduces friction and built-up edge on many workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and direct-fit boring bar for standard 0.5-inch boring bar holders used on CNC turning centers and manual lathes requiring a right-hand, helical-style internal cutting tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the machine is placed in an appropriate lockout state before mounting or removing the boring bar. Secure the 0.5-inch shank firmly in the boring bar holder to the tool manufacturer's recommended clamping procedure to minimize overhang deflection. Verify boring bar runout with a dial indicator before beginning a finishing pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.48 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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 0.40625 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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-HB4803000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":67587900637490,"sku":"ACC-HB4803000","price":126.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ff77c6860bf50b553a488b46cfb90ae.jpg?v=1790418012","url":"https:\/\/voomisupply.com\/products\/accupro-acc-hb4803000-helical-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
