It features a 0.12-inch minimum bore diameter, a maximum bore depth of 0.5 inches, and a 3\/16-inch shank diameter, making it well suited for tight-tolerance small-bore work. The right-hand cutting direction and 0.003-inch corner radius support clean, accurate finishes in small bores where tool rigidity and geometry are critical. Solid carbide construction provides the stiffness and wear resistance needed for consistent performance in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for small-bore internal turning applications in precision machining. With an overall length of 1.5 inches and a shank diameter of 3\/16 inches, it fits compact tool holders used on small lathes, CNC turning centers, and manual engine lathes. It is appropriate for machinists working with tight bore tolerances in ferrous and non-ferrous materials where carbide rigidity minimizes deflection and chatter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003e0.12-inch minimum bore diameter for small-bore internal turning\u003c\/li\u003e\n\u003cli\u003e0.5-inch maximum bore depth suitable for shallow precision bores\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard lathe setups\u003c\/li\u003e\n\u003cli\u003e0.003-inch corner radius for controlled surface finish\u003c\/li\u003e\n\u003cli\u003e3\/16-inch shank diameter fits compact small-bore tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a small-bore internal turning tool for use in compatible 3\/16-inch shank boring bar holders on manual and CNC lathes or turning centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the shank is clamped securely in a compatible tool holder with adequate stick-out minimized to reduce deflection. Follow machine tool manufacturer guidelines for tool holder torque and setup procedures. Inspect the cutting edge before use and handle carbide tooling carefully to avoid chipping.\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: 0.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.5 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: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.003 inches\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: 0.016 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: QBB-120500X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":52064655606066,"sku":"QBB-120500X","price":74.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81b41030e96223f7f8e4d39efdc44671_0c233409-3ca1-4d03-ba39-652097b18379.jpg?v=1790044275","url":"https:\/\/voomisupply.com\/products\/micro-100-qbb-120500x-boring-bar-right-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
