Built from submicron-grade carbide with a bright finish, it delivers the rigidity and edge retention needed for tight-tolerance bore work in ferrous and non-ferrous materials. The bar accepts a minimum bore diameter of 0.23 inches and reaches a maximum bore depth of 0.40 inches. With a 5\/16-inch shank diameter and a 2.5-inch overall length, it fits standard tool holders used in light to medium turning operations. Right-hand cutting direction is standard. Machinists and toolroom technicians working with small-bore applications will find this bar suitable for finishing and semi-finishing passes.\u003c\/p\u003e\u003cp\u003eThe ACC-BB230400 is suited for small-bore internal turning operations in job shop, production, and toolroom environments. It is appropriate for use on CNC lathes, manual engine lathes, and boring mills where bore diameters in the 0.23-inch-and-up range are required. The submicron carbide substrate supports consistent cutting performance in both interrupted and continuous cuts at small diameters. The bright finish coating keeps the surface clean and reduces built-up edge in non-ferrous and some ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for rigidity and edge retention at small bore diameters\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.23 inches for tight small-bore applications\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.40 inches\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank diameter fits standard small-bore tool holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eBright finish coating reduces built-up edge and aids chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank boring bar compatible with tool holders accepting a 5\/16-inch shank diameter for small-bore internal turning operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Secure the shank firmly in the tool holder to the full recommended engagement depth before operation to minimize overhang and vibration. Power down and lock out the machine spindle before changing or adjusting tooling. Inspect the cutting edge for chipping or wear before each use, as carbide tooling at small diameters is sensitive to improper setup and interrupted cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Boring\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: 0.23 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.40 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (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\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\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-BB230400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733160821042,"sku":"ACC-BB230400","price":72.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c65012d52e80ac8f79c8964781682676.jpg?v=1788752100","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb230400-boring-bar-submicron-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
