With a minimum bore diameter of 0.039 inches and a maximum bore depth of 0.236 inches, this bar handles tight, small-diameter bores that require consistent geometry and surface finish. The right-hand cutting direction and 0.004-inch corner radius make it suitable for fine profiling passes in hardened or difficult-to-machine materials. Solid carbide construction in the MG12 grade provides the rigidity and wear resistance required for repeatable results in production environments. Machinists and toolroom technicians working on Swiss-type, CNC turning, or multi-axis machines will find this bar a reliable choice for small-bore applications.\u003c\/p\u003e\n\u003cp\u003eThis profile boring bar is intended for small-bore internal machining operations on CNC lathes, Swiss-style machines, and multi-spindle turning centers. It is particularly suited for applications where bore diameter clearance is tight and depth-to-diameter ratios demand a rigid, compact tool. The uncoated solid carbide construction allows for use across a range of workpiece materials including steel, stainless, aluminum, and non-ferrous alloys. Professional machinists and CNC operators in precision manufacturing and job shop environments are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMinimum bore diameter of 0.039 inches for tight, small-bore internal profiling\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 0.236 inches supports controlled depth passes\u003c\/li\u003e\n  \u003cli\u003eSolid carbide MG12 grade construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard CNC turning setups\u003c\/li\u003e\n  \u003cli\u003e0.004-inch corner radius for fine profile geometry and surface finish\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use across a variety of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style tooling component for small-bore internal profile turning operations on CNC turning centers and Swiss-type machines that accept this shank diameter and overall length configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and setup should be performed by a qualified machinist or CNC toolroom technician. Ensure the machine spindle is fully stopped and the machine is placed in a safe state before mounting or removing any cutting tool. Verify that the shank diameter and overall length are compatible with the tool holder before mounting. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool offsets and running initial passes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Profile Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.039 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.236 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.9843 inches (25.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.65 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.004 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\u003eManufacturer Grade\u003c\/strong\u003e: MG12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: HORN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R105180511 MG12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HORN","offers":[{"title":"Default Title","offer_id":67915331010866,"sku":"R105180511 MG12","price":110.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a158f8378ccc7db7a8cce48bd4439012.jpg?v=1791253154","url":"https:\/\/voomisupply.com\/products\/horn-r105180511-mg12-profile-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
