With a minimum bore diameter of 0.14 inches and a maximum bore depth of 0.75 inches, this bar handles tight, shallow bores where rigidity and edge retention are critical. The 3\/16-inch shank diameter and 2-inch overall length make it well suited for small-bore applications in production and toolroom environments. A titanium nitride (TiN) finish coating improves surface hardness and reduces friction at the cutting edge, extending tool life in ferrous and non-ferrous materials. Right-hand cut geometry follows standard lathe rotation conventions.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for machinists and tool-and-die professionals working on precision components that require tight bore tolerances. Typical applications include finish boring of small holes in steel, cast iron, aluminum, and brass workpieces on engine lathes and turning centers. The micrograin carbide substrate provides the fine grain structure needed to hold a sharp edge and maintain dimensional accuracy across repeated passes in short-run and high-volume production alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003eTiN finish coating reduces cutting friction and extends tool life\u003c\/li\u003e\n  \u003cli\u003e0.14-inch minimum bore diameter suits small and tight bore geometries\u003c\/li\u003e\n  \u003cli\u003e0.75-inch maximum bore depth in a compact 2-inch overall length\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch shank diameter for standard small-bore tool holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut geometry compatible with standard lathe rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct toolroom addition for standard tool holders accepting a 3\/16-inch round shank boring bar.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists familiar with lathe tooling setup. Ensure the machine spindle is fully stopped and locked out before mounting or removing the boring bar. Secure the shank firmly in the tool holder with adequate clamping contact along the shank to minimize overhang-induced vibration. Follow shop safety procedures and applicable OSHA machining guidelines when setting tool offsets and running initial test passes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.14 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: 0.1875 inches (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\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 (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 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: ACC-BB140750G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729081041202,"sku":"ACC-BB140750G","price":49.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2522817c6e6e1863fe00a8115eeb5141.jpg?v=1788699674","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb140750g-boring-bar-solid-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
