Machined from submicron-grade solid carbide, this bar delivers the rigidity and edge retention required for tight-tolerance bore work. It accepts a minimum bore diameter of 0.3 inches and handles a maximum bore depth of 1 inch, making it well suited for shallow to mid-depth internal features. The 5\/16-inch shank diameter and 2.5-inch overall length keep the tool compact and compatible with standard boring bar holders on lathes and machining centers. A bright finish coating is applied to the carbide substrate. Right-hand cutting direction is standard on this model.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for use by machinists and tool-and-die professionals working on CNC lathes, manual lathes, and machining centers requiring small-diameter internal boring. It is suited for ferrous and non-ferrous workpiece materials where a solid carbide helical geometry provides improved chip evacuation and surface finish compared to straight-flute designs. Typical applications include bore finishing, diameter correction, and small-feature internal profiling in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eHelical boring bar geometry promotes efficient chip flow during internal operations\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.3 inches supports small-diameter internal features\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 1 inch suitable for shallow and mid-depth bore applications\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch shank diameter fits standard small-bore toolholders\u003c\/li\u003e\n  \u003cli\u003eBright finish coating on carbide substrate\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and direct-fit cutting tool for standard boring bar toolholders accepting a 5\/16-inch shank diameter on CNC and manual lathes or machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholding and torque guidelines. Ensure the machine spindle is fully stopped and the machine is placed in an e-stop or locked-out state before changing tooling. Set tool overhang to the minimum length required for the application to maximize rigidity and minimize deflection. Verify shank seating and clamping before commencing any cutting operation.\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: 0.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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: 0.125 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-HB3001000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731080249650,"sku":"ACC-HB3001000","price":56.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d98545ae5027ac61d6260726fcd1d66.jpg?v=1788726718","url":"https:\/\/voomisupply.com\/products\/accupro-acc-hb3001000-helical-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
