It features a minimum bore diameter of 0.140 inches (9\/64 inches), a maximum bore depth of 0.250 inches (1\/4 inches), and a 3\/16-inch shank diameter. The right-hand cutting direction and 0.006-inch corner radius make it suited for precision finishing and sizing passes in tight bore geometries. At 2 inches overall length and weighing 0.028 pounds, it fits compact toolholders and small lathes or boring setups. Machinists and tool-and-die professionals are the primary users of this type of tooling.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in precision machining environments where small internal diameters require consistent, repeatable material removal. Typical applications include finish boring of small holes in metal workpieces on CNC lathes, manual lathes, or dedicated boring machines. The solid carbide construction supports use in harder workpiece materials and delivers the rigidity needed to hold tight tolerances in shallow-depth bores.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in small-bore machining\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.140 inches (9\/64 inches) for access to tight internal geometries\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.250 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe rotation\u003c\/li\u003e\n\u003cli\u003e0.006-inch corner radius for controlled surface finish on bore walls\u003c\/li\u003e\n\u003cli\u003e3\/16-inch shank diameter for compatibility with standard small-bore toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for small-bore internal diameter operations on lathes and boring machines accepting a 3\/16-inch shank boring bar.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists. Ensure the machine spindle is fully stopped and locked out before mounting or adjusting the boring bar. Secure the shank firmly in the toolholder to minimize overhang and reduce chatter risk. Verify bore diameter and depth clearances against the workpiece 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: 0.140 inches (9\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.250 inches (1\/4 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: 0.028 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-140250G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":51974236963122,"sku":"BB-140250G","price":65.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7aa82526ff56a22a56960b8a62a04582_4cd7603d-f03b-4ce7-b2af-645fb947dc04.jpg?v=1789976504","url":"https:\/\/voomisupply.com\/products\/micro-100-bb-140250g-boring-bar-solid-carbide-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
