Built from submicron-grade carbide and finished with an AlTiN (aluminum titanium nitride) coating, this bar resists heat and wear during demanding cutting operations. It features a 0.32 inch minimum bore diameter, a 3 inch maximum bore depth, and a 3\/8 inch shank diameter with a 4 inch overall length. The right-hand cutting direction suits standard CNC and manual lathe setups. Machinists and tool-and-die professionals rely on this type of bar for tight-tolerance bore finishing and sizing work.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for shops performing internal turning, bore finishing, and diameter sizing on ferrous and non-ferrous materials. The submicron carbide substrate provides the rigidity needed for deep-reach boring passes where chatter control and dimensional accuracy are critical. The AlTiN coating extends tool life in high-temperature cutting environments, making it appropriate for production runs as well as precision one-off work on CNC lathes and boring mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish coating enhances heat resistance and extends tool life\u003c\/li\u003e\n  \u003cli\u003e0.32 inch minimum bore diameter for small-diameter internal machining\u003c\/li\u003e\n  \u003cli\u003e3 inch maximum bore depth supports reach into deeper bores\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch shank diameter fits standard boring bar holders and quick-change tooling systems\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for conventional lathe and CNC turning setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fit for boring bar holders accepting a 3\/8 inch shank diameter in CNC lathes, manual lathes, and boring mills configured for right-hand internal turning operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state per applicable shop safety procedures. Secure the shank firmly in the boring bar holder to the specified clamping torque listed in the toolholder manufacturer documentation. Inspect the cutting edge for chips or coating damage before each use. Do not exceed the rated bore depth or minimum bore diameter, as doing so may cause tool deflection or breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 0.25 inches W x 0.25 inches H x 2.75 inches L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.375 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: B3203000A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739094417714,"sku":"B3203000A","price":102.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff489e16503cbc4bd5389828c8461c8b.jpg?v=1788809301","url":"https:\/\/voomisupply.com\/products\/accupro-b3203000a-boring-bar-0-32-in-min-bore-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
