Built from micrograin solid carbide with a TiAlN finish coating, this bar delivers the rigidity and wear resistance needed for tight-tolerance bores in ferrous and non-ferrous materials. It features a right-hand cutting direction, a minimum bore diameter of 0.29 inches, a maximum bore depth of 1 inch, a 5\/16-inch shank diameter, and an overall length of 2.5 inches. Machinists and tool-and-die professionals rely on this class of tooling for small-diameter internal finishing work where deflection must be minimized.\u003c\/p\u003e\u003cp\u003eThe ACC-BB2901000A is suited for small-bore internal turning applications in job shops, production machining environments, and maintenance repair operations. The 5\/16-inch shank fits standard boring bar holders and quick-change tool posts sized for that shank diameter. Its 1-inch maximum bore depth makes it appropriate for through-holes and blind bores in short-run and production workpieces. The micrograin carbide substrate supports interrupted cuts and harder workpiece materials better than standard-grain carbide grades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eTiAlN finish coating improves heat resistance and wear performance in dry and semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e0.29 inch minimum bore diameter supports small internal diameters\u003c\/li\u003e\n\u003cli\u003e1 inch maximum bore depth suitable for short through-holes and blind bores\u003c\/li\u003e\n\u003cli\u003e5\/16 inch shank diameter fits standard boring bar holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for conventional lathe setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank boring bar for use in tool holders and quick-change systems that accept a 5\/16-inch shank diameter on CNC and manual turning centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard lathe tooling procedures. Ensure the machine spindle is fully stopped and the machine is powered down or in a safe locked-out state before installing or removing tooling. Secure the shank firmly in the tool holder to the appropriate clamping specification for your holder make and model. Verify boring bar overhang is minimized to reduce deflection and chatter during the cut.\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: 0.29 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: 0.3125 inches (5\/16)\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: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiAlN\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-BB2901000A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749257576754,"sku":"ACC-BB2901000A","price":77.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c0a3193aaa83357e4be8f29cc5d65a6.jpg?v=1788903676","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb2901000a-boring-bar-right-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
