With a minimum bore diameter of 0.160 inches and a maximum bore depth of 0.400 inches, this tool is suited for small-bore applications where dimensional accuracy is critical. The 3\/16-inch shank diameter and 1.5-inch overall length make it compact and rigid. A 0.003-inch corner radius reduces stress concentration at the cutting edge. Right-hand cutting direction is standard for conventional lathe and boring mill setups. Machinists and tool-room operators working with CNC turning centers or manual lathes will find this bar appropriate for fine-finishing passes in small bores.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in metalworking environments requiring precise internal turning of small-diameter features. Typical applications include finishing bores in workholding components, tooling blocks, hydraulic bodies, and precision mechanical assemblies. The solid carbide construction offers greater rigidity than steel-shank alternatives, which is especially important when reach-to-diameter ratios are extended. It is installed in standard boring bar holders or block-style tool holders compatible with the 3\/16-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides high rigidity and wear resistance in small-bore applications\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.160 inches for tight internal diameter work\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.400 inches suits shallow to moderate reach requirements\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with conventional lathe rotation\u003c\/li\u003e\n\u003cli\u003e0.003-inch corner radius for controlled surface finish at the cutting edge\u003c\/li\u003e\n\u003cli\u003eCompact 1.5-inch overall length reduces overhang and vibration tendency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in boring bar holders or block tool holders accepting a 3\/16-inch round shank, as commonly found on CNC turning centers, manual lathes, and boring mills used in precision metalworking.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolroom procedures. Secure the shank fully within the tool holder to the recommended grip length before engaging the workpiece. Power down and de-energize the machine spindle before changing or adjusting tooling. Verify shank runout and tool overhang before taking finishing passes to minimize chatter in small-bore conditions.\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: 0.160 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 (0.1875 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\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: 0.018 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-160400X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":52114190926130,"sku":"QBB-160400X","price":74.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81b41030e96223f7f8e4d39efdc44671_b62ca25c-de6f-4adb-91ba-f1835f65ecdb.jpg?v=1790078829","url":"https:\/\/voomisupply.com\/products\/micro-100-qbb-160400x-boring-bar-solid-carbide-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
