It has a minimum bore diameter of 0.14 inches and a maximum bore depth of 0.8 inches, making it well suited for tight-tolerance small-bore work. The TiN (titanium nitride) finish coating extends tool life and reduces built-up edge at the cutting surface. With a 3\/16-inch shank diameter and a 2-inch overall length, this bar fits standard toolholders used in production and job shop environments. Installation and setup are handled by machinists and CNC operators.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for applications requiring precise small-bore finishing or semi-finishing cuts in metalworking operations. The right-hand cutting direction suits conventional lathe setups where the tool moves from right to left along the workpiece. The micrograin carbide substrate provides a fine grain structure that supports sharper edges and improved surface finish in ferrous and non-ferrous materials. It is commonly used in production shops, tool rooms, and maintenance machining environments where consistent bore geometry is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for sharp edges and extended tool life\u003c\/li\u003e\n\u003cli\u003eTiN finish coating reduces friction and wear at the cutting zone\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.14 inches suits small-bore precision work\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.8 inches\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe orientation\u003c\/li\u003e\n\u003cli\u003e3\/16-inch shank diameter fits common small-bore toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit boring bar for standard toolholders accepting a 3\/16-inch shank diameter in CNC and manual turning applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis boring bar is installed by machinists or CNC operators. Power down and lock out the machine spindle before changing or setting tooling. Secure the shank firmly in the toolholder to the recommended clamping depth to minimize overhang and chatter. Verify boring bar runout and bore diameter with an appropriate gauge before committing to finish passes.\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: 0.14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 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\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\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-BB140800G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734219424050,"sku":"ACC-BB140800G","price":47.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c28c3364b6e3a0169bf6a44db61bacd5.jpg?v=1788761394","url":"https:\/\/voomisupply.com\/products\/accupro-acc-bb140800g-boring-bar-micrograin-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
