It features a micrograin carbide substrate with a TiN finish coating, delivering enhanced wear resistance and edge retention in a compact, rigid body. The bar accepts a minimum bore diameter of 0.49 inches and reaches a maximum bore depth of 0.75 inches, making it well suited for small-bore precision work. The 0.5 inch shank diameter and 3 inch overall length provide a stable platform for tight-tolerance applications. Right-hand cutting geometry is standard. Installation is handled by machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in precision machining environments where small internal diameters and controlled depths are required. It fits standard tool holders with a 0.5 inch shank bore and is appropriate for both production and job shop settings. Typical applications include finish boring of bushings, bearing housings, and similar small-diameter features in ferrous and non-ferrous materials. The TiN coating extends tool life across a range of cutting speeds and materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN finish coating for extended tool life and reduced friction\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe and machining center setups\u003c\/li\u003e\n\u003cli\u003e0.49 inch minimum bore diameter for precise small-bore applications\u003c\/li\u003e\n\u003cli\u003e0.5 inch shank diameter compatible with standard tool holders\u003c\/li\u003e\n\u003cli\u003e3 inch overall length provides reach with minimal overhang\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard tool holders accepting a 0.5 inch shank diameter; suitable for lathes and machining centers configured for right-hand internal boring operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Secure the shank firmly in the tool holder to the manufacturer-specified clamping torque for the holder used, minimizing overhang to reduce chatter. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the boring bar. Follow applicable shop safety procedures and machine tool manufacturer guidelines when setting cutting parameters.\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: 0.49 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3125 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-BB490750G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740933128498,"sku":"ACC-BB490750G","price":125.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08d65fd5bf41be8b4bfa8c1e5fac1847.jpg?v=1788828448","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb490750g-boring-bar-micrograin-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
