It features a right-hand cutting direction, a minimum bore diameter of 0.48 inches, and a maximum bore depth of 2.5 inches. The 0.5-inch shank diameter provides rigid tool holding, and the bright finish coating reduces built-up edge during cutting. With an overall length of 4 inches, this bar suits close-tolerance bore work in ferrous and non-ferrous materials. It is selected by machinists and tooling specialists who require consistent dimensional accuracy in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for internal diameter finishing and semi-finishing passes where bore geometry and surface finish tolerance are critical. The helical flute geometry promotes chip evacuation during deeper passes up to 2.5 inches. Typical applications include bore sizing on turned components, fixture bores, and bearing-fit surfaces in both low-volume prototype and production-run settings. The submicron carbide grade supports higher cutting speeds and maintains edge integrity longer than standard carbide grades under consistent chip loads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for extended edge life and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eHelical boring bar geometry promotes chip clearance during deeper bore passes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.48 inches suits small-bore internal turning operations\u003c\/li\u003e\n  \u003cli\u003eBright finish coating reduces friction and built-up edge on the cutting edge\u003c\/li\u003e\n  \u003cli\u003e0.5-inch shank diameter fits standard ER and straight-bore toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling selection for CNC lathes and manual turning centers accepting a 0.5-inch shank boring bar in a straight-bore or collet-style toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machining technicians and CNC setup personnel. Secure the 0.5-inch shank in a properly sized boring bar holder and confirm tool overhang does not exceed recommended length-to-diameter ratios for the material being cut. Power down and lock out the spindle before mounting or removing any cutting tool. Do not exceed the bore depth capacity of 2.5 inches in a single setup, and confirm workpiece clamping before initiating a cut.\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: 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\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\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: 0.406 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-HB4802500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732170801458,"sku":"ACC-HB4802500","price":113.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d10b056aa8554b5624e97f766a1d0179.jpg?v=1788739984","url":"https:\/\/voomisupply.com\/products\/accupro-acc-hb4802500-helical-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
