It cuts right-hand and reaches a minimum bore diameter of 0.05 inches with a maximum bore depth of 0.3 inches. The 1\/8-inch shank diameter and 1-1\/2-inch overall length make it well suited for small-bore finish work where rigidity and dimensional accuracy are critical. A TiAlN coating improves heat resistance and tool life when cutting ferrous and hardened materials at elevated speeds. Machinists and tool-and-die professionals are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for small-bore internal turning applications in job shops, production machining environments, and toolrooms. It is appropriate for use on steel, stainless, cast iron, and similar ferrous workpiece materials where a hard, heat-resistant coating is beneficial. The compact shank diameter of 1\/8 inch suits tight-clearance bores and miniature component work where larger tooling cannot access the feature geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimum bore diameter of 0.05 inches for small and miniature bore applications\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.3 inches suits shallow internal features\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides hardness and edge integrity\u003c\/li\u003e\n\u003cli\u003eTiAlN finish coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe and boring head setups\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits compact tool holders and micro-boring heads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit boring bar for tool holders and boring heads accepting a 1\/8-inch round shank in standard CNC lathe and machining center setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the tool holder manufacturer specifications for clamping torque and shank engagement depth. Ensure the machine spindle is fully stopped and the control is in an e-stop or lockout state before changing tooling. Confirm shank seating depth meets the tool holder minimum engagement requirement to prevent deflection during cutting. Follow applicable shop safety procedures and machine guarding requirements during setup.\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: 0.05 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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: 0.0625 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-BB050300A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750600278322,"sku":"ACC-BB050300A","price":47.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac69c273848912449186e619950201bd.jpg?v=1788917214","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb050300a-boring-bar-micrograin-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
