It cuts in a right-hand direction and accepts a minimum bore diameter of 0.25 inches, making it suitable for tight-tolerance bore work in small-diameter applications. The shank diameter measures 5\/16 inches with an overall length of 2.5 inches. An AlTiN finish coating improves heat resistance and extends tool life in ferrous and hardened materials. This bar is part of the MICRO 100 Quick Change boring tool series and is typically installed by machinists and toolroom professionals working in precision turning environments.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for small-bore internal turning applications in job shop, production, and toolroom settings. It handles residential-scale precision work on CNC and manual lathes where bore diameters start at 0.25 inches and maximum bore depth reaches 1.2 inches. The right-hand cutting geometry and tight corner radius of 0.005 inches support fine surface finish requirements in steel, stainless, and hardened workpieces. Professionals running MICRO 100 Quick Change tooling systems will find this bar integrates directly into that platform.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and vibration resistance in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish coating increases surface hardness and thermal resistance for longer tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with 0.25 inch minimum bore diameter\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 1.2 inches with 0.058 inch projection\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.005 inches for tight-tolerance surface finish work\u003c\/li\u003e\n  \u003cli\u003ePart of the MICRO 100 Quick Change boring tool series for compatible tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the MICRO 100 Quick Change boring tool system. Compatible with setups requiring a 5\/16 inch shank diameter and a minimum bore diameter of 0.25 inches.

Power down and lock out the machine spindle before inserting or removing the boring bar from the holder. Ensure the shank is fully seated and the set screw or clamping mechanism is torqued per the toolholder manufacturer specifications. Inspect the cutting edge for chips or wear before each use, and confirm bore depth and offset settings match the programmed toolpath before beginning 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 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\u003eOffset\u003c\/strong\u003e: 0.0738 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.058 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\u003eSeries\u003c\/strong\u003e: Quick Change - Boring Tools - Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: QBB5-2301200X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":52087232364850,"sku":"QBB5-2301200X","price":103.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81b41030e96223f7f8e4d39efdc44671_252409a6-3355-49e5-8a19-c9ec2df527c8.jpg?v=1790060179","url":"https:\/\/voomisupply.com\/products\/micro-100-qbb5-2301200x-boring-bar-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
