It features a 0.360 inch minimum bore diameter and handles bore depths up to 1 inch, making it well suited for tight-tolerance finishing passes in small-diameter bores. The 3\/8 inch shank diameter provides rigid tooling engagement, and the 0.0060 inch corner radius supports clean surface finishes in both steel and non-ferrous materials. At 2.5 inches overall length, the bar is compact and direct-mounted without extension. Machinists and toolroom technicians install this bar as a standard internal turning tool.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for right-hand cutting operations on turning equipment where small-bore internal features require precise diameter control. It is applicable in job shop and production environments handling components that require finished bores in the 0.360 inch range. Typical applications include bearing seats, hydraulic valve bodies, and similar precision-machined bores where surface finish and diameter accuracy are critical. The solid carbide construction supports higher cutting speeds compared to high-speed steel alternatives.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e0.360 inch minimum bore diameter for small internal features\u003c\/li\u003e\n  \u003cli\u003e1 inch maximum bore depth for moderate-depth internal turning\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch shank diameter for standard tool post and boring head compatibility\u003c\/li\u003e\n  \u003cli\u003e0.0060 inch corner radius for clean surface finish on bore walls\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard lathe spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-mount internal turning tool compatible with tool holders and boring heads accepting a 3\/8 inch round shank on CNC and manual lathes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis boring bar is installed by machinists using a tool post, turret holder, or boring head sized for a 3\/8 inch shank. Secure the shank with adequate clamping length to minimize overhang and chatter. Power down and lock out the spindle before mounting or adjusting the tool. Follow machine tool manufacturer guidelines for tool projection limits relative to bore depth to maintain rigidity during the cut.\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: 0.3600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0060 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: 0.116 pounds\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: MICRO 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: QBT-3601000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":51969979777330,"sku":"QBT-3601000","price":112.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fbaeeefc507d154cf05036be2214f730.jpg?v=1789952634","url":"https:\/\/voomisupply.com\/products\/micro-100-qbt-3601000-solid-carbide-boring-bar-3-8in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
