With a minimum bore diameter of 0.29 inches and a maximum bore depth of 0.5 inches, this right-hand cutting tool handles tight-tolerance small-bore work with the rigidity and wear resistance that solid carbide construction provides. The 5\/16-inch shank diameter keeps the tool compact and well-suited to sub-half-inch bore applications. At 2 inches overall length and a 0.005-inch corner radius, it is built for precision finish passes as well as light roughing in small bores.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in precision machining environments including job shops, tool rooms, and production turning operations. It is suited for residential or commercial machine shop use where small-diameter internal turning is required. The right-hand cutting direction is the standard orientation for conventional lathe setups. Machinists working in medical, aerospace, or general manufacturing where close-tolerance bores are common will find this tool appropriate for those finishing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high rigidity and extended tool life in small-bore applications\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.29 inches enables work in tightly dimensioned internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.5 inches suits through and blind bore operations at this diameter range\u003c\/li\u003e\n\u003cli\u003e0.005-inch corner radius provides a controlled edge geometry for finish-quality surface results\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank diameter fits standard small-bore toolholders and quick-change systems\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for conventional lathe and turning center setups\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 toolholding systems accepting a 5\/16-inch shank diameter in right-hand boring bar configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool overhang and shank clamping torque. Power down and lock out the spindle before inserting or removing the boring bar from the toolholder. Minimize tool overhang to reduce deflection and chatter, particularly at this bore diameter range. Confirm proper tool height alignment to centerline before taking the first 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.29 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: 5\/16 inches (0.3125 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: 0.005 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: 0.066 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-290500X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":52091853013298,"sku":"QBB-290500X","price":103.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81b41030e96223f7f8e4d39efdc44671_18faa72c-c826-46a1-8ac7-1447fa97f274.jpg?v=1790063434","url":"https:\/\/voomisupply.com\/products\/micro-100-qbb-290500x-boring-bar-solid-carbide-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
