Built from micrograin carbide stock and finished with a TiAlN coating, it delivers wear resistance and thermal stability in demanding cutting applications. The bar handles a minimum bore diameter of 0.29 inches and a maximum bore depth of 1.5 inches, making it well suited for small-diameter, short-reach bores where rigidity and accuracy are critical. The 5\/16-inch shank diameter and 2.5-inch overall length give machinists a compact, stiff tool body that minimizes deflection at depth.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in job shops, tool rooms, and production machining environments where tight tolerances on bored features are required. It is appropriate for ferrous and non-ferrous materials in applications calling for a right-hand cutting direction. The right-hand cut configuration fits standard boring bar holders and quick-change tool posts commonly found on manual and CNC lathes. It is installed and operated by machinists, toolroom technicians, and CNC setup personnel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for improved rigidity and edge retention over standard carbide grades\u003c\/li\u003e\n\u003cli\u003eTiAlN finish coating provides enhanced heat resistance and extended tool life in dry and semi-dry cutting conditions\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.29 inches supports small-diameter internal boring applications\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.5 inches suitable for short-reach precision bores\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank diameter compatible with standard boring bar holders and tool posts\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for conventional lathe setup orientation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for boring bar holders accepting a 5\/16-inch shank with right-hand cutting orientation on manual and CNC lathes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis boring bar is installed by machinists and toolroom technicians following standard lathe tooling practices. Power down and lock out the machine before securing the bar in the tool holder, ensuring the shank is fully seated and clamped to the specified holder requirements. Do not exceed the maximum bore depth rating of 1.5 inches, as overhang beyond rated depth increases deflection and risk of tool failure. Verify cutting direction and clearance angles match the workpiece setup before initiating a 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\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.29 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.5 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003ePackage Dimensions\u003c\/strong\u003e: 2.63 inches x 0.38 inches x 0.38 inches\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-BB2901500A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51786874093874,"sku":"ACC-BB2901500A","price":77.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0384911fb06fb5f06a82412b441c5635_7d31dbac-6e90-44fd-a438-596627e4ab0a.jpg?v=1789207648","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb2901500a-boring-bar-micrograin-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
