It handles a minimum bore diameter of 0.48 inches and reaches a maximum bore depth of 4 inches, making it well-suited for through-bores and blind-bores in small-to-medium workpieces. The 0.5-inch shank diameter seats securely in standard tool holders, and the 6-inch overall length provides clearance for most turret and gang-tool setups. The bright finish coating keeps the surface clean and aids chip flow. Machinists and tool-and-die professionals select this bar when tight tolerances and surface finish are the priority.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is used in production and job-shop environments where consistent bore geometry is required. The helical flute geometry promotes efficient chip evacuation during interrupted or continuous cuts in ferrous and non-ferrous materials. The right-hand cutting direction is compatible with standard spindle rotation on conventional CNC turning centers and manual lathes. It is appropriate for shop applications where a solid carbide tool is preferred over carbide-tipped or steel-shank alternatives due to rigidity and vibration resistance at depth-to-diameter ratios common in small-bore work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eHelical flute geometry promotes chip evacuation in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.48 inches suits tight internal features\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 4 inches covers through and blind-bore applications\u003c\/li\u003e\n  \u003cli\u003eBright finish coating reduces built-up edge and aids chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement-style solid carbide helical boring bar for use with standard 0.5-inch shank tool holders on CNC lathes, manual lathes, and machining centers requiring right-hand internal boring capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Secure the 0.5-inch shank fully into the tool holder bore and torque the clamping screws according to the tool holder manufacturer specifications before operation. Power down and lock out the spindle before changing or adjusting tooling. Inspect the carbide cutting edge for chipping before each use, as solid carbide is brittle and sensitive to impact during handling.\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 4 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: 6 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: 0.625 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-HB4804000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746622144818,"sku":"ACC-HB4804000","price":142.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/70365cd2b75086ed848a2f6413974757.jpg?v=1788871879","url":"https:\/\/voomisupply.com\/products\/accupro-acc-hb4804000-helical-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
