Built from submicron-grade carbide and finished with an AlTiN coating, it delivers hard, wear-resistant cutting performance in ferrous and hardened materials. The right-hand cutting geometry suits standard spindle rotation setups. With a minimum bore diameter of 0.29 inches and a maximum bore depth of 1.6 inches, this bar handles tight, shallow bores where rigidity and dimensional accuracy are critical. The 5\/16-inch shank diameter keeps it compact for small-bore toolholders.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for precision machining environments including job shops, production floors, and tool rooms. It is a practical choice for machinists running small-bore finishing or semi-finishing passes where submicron carbide grain structure reduces chatter and extends tool life. The AlTiN coating adds thermal resistance, making it effective in dry or minimal-lubrication cutting strategies. It fits toolholding systems configured for a 5\/16-inch shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for heat resistance and wear protection in demanding cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard lathe spindle rotation\u003c\/li\u003e\n\u003cli\u003e0.29 inches minimum bore diameter for small internal diameter work\u003c\/li\u003e\n\u003cli\u003e1.6 inches maximum bore depth for shallow to moderate boring reaches\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank diameter fits compact boring toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in boring toolholders and quick-change systems accepting a 5\/16-inch shank diameter, suitable for CNC and manual turning applications requiring right-hand internal boring.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified machinist. Secure the shank firmly in the toolholder to the manufacturer-specified clamping torque for the holder in use, and verify shank runout before cutting. Power down and lock out the machine spindle before inserting or removing the boring bar. Avoid overhang beyond the maximum bore depth rating to prevent deflection and premature tool wear.\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: 1.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inch)\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: AlTiN\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: B2901600A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746323071282,"sku":"B2901600A","price":66.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07adc1187cdcc725e1615c9c69ccc860.jpg?v=1788868337","url":"https:\/\/voomisupply.com\/products\/accupro-b2901600a-boring-bar-submicron-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
