It accepts a minimum bore diameter of 9\/64 inches (0.140 inches) and reaches a maximum bore depth of 0.400 inches, making it well suited for tight, shallow bores in small-diameter workpieces. The 3\/16-inch shank diameter and 2-inch overall length give machinists a rigid, compact tool that fits standard boring bar holders. A 0.006-inch corner radius reduces stress concentration at the cutting edge and helps produce a consistent finish. This bar is used by machinists and toolroom professionals working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe BB-140400 is intended for right-hand cutting operations in small-bore applications where solid carbide rigidity is required to maintain dimensional accuracy. Typical use cases include boring precision holes in ferrous and non-ferrous materials on lathes and boring mills. Its compact geometry makes it a practical choice for instrument-scale parts, medical components, and other applications requiring tight bore tolerances at shallow depths.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in demanding bore applications\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 9\/64 inches (0.140 inches) enables work on very small-diameter holes\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 0.400 inches suits shallow internal features\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard lathe spindle rotation\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch shank diameter fits common small boring bar holders\u003c\/li\u003e\n  \u003cli\u003e0.006-inch corner radius for controlled edge geometry and finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for lathes and boring mills equipped with 3\/16-inch boring bar holders requiring right-hand, solid carbide internal boring tools.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolroom procedures. Ensure the machine is fully powered down and the spindle is locked before mounting or removing boring bars. The shank must be clamped securely in the tool holder with adequate engagement to prevent deflection during the cut. Follow applicable shop safety standards and machine manufacturer guidelines for tool overhang and cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 9\/64 inches (0.140 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.006 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\u003eWeight\u003c\/strong\u003e: 0.026 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: MICRO 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BB-140400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":52012228706610,"sku":"BB-140400","price":61.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1bf8437a3a4be64a5db0be695effd036_47effffd-bed6-4dc5-a733-06fce5504a4a.jpg?v=1790005278","url":"https:\/\/voomisupply.com\/products\/micro-100-bb-140400-solid-carbide-boring-bar-9-64-in-rh","provider":"Voomi Supply","version":"1.0","type":"link"}
