With a minimum bore diameter of 0.16 inches and a maximum bore depth of 0.59 inches, this right-hand-cut tool is built for precision work in tight bore geometries. The bright finish coating reduces friction and aids chip flow during cutting. An overall length of 2 inches and a 4 mm shank diameter make it compatible with standard small-bore toolholding systems. Machinists and tool-and-die professionals use this bar where accurate internal profile geometry and surface finish are critical requirements.\u003c\/p\u003e\n\u003cp\u003eThis profile boring bar is suited for CNC lathe and turning center applications where small internal bores require consistent profile geometry. The 0.008-inch corner radius allows for controlled profile transitions in threading, grooving, and form-turning operations. It is appropriate for use in both job-shop and production environments handling small precision components in materials suited to solid carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard lathe setups\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.16 inches enables work in very small internal features\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 0.59 inches provides adequate reach for typical small-bore profiles\u003c\/li\u003e\n  \u003cli\u003e0.008-inch corner radius for controlled profile and form transitions\u003c\/li\u003e\n  \u003cli\u003eBright finish coating reduces built-up edge and aids chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style profile boring bar for use with toolholding systems accepting a 4 mm shank diameter on CNC lathes and turning centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the machine spindle is fully stopped and locked out before mounting or removing the boring bar. Confirm proper shank clamping torque per the toolholder manufacturer's guidelines and verify bore alignment before initiating a cut. Inspect the cutting edge for chipping or wear before each use.\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: 0.16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.008 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\u003eFinish Coating\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01764 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: CARMEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MPR4R0.2L15\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51985465966898,"sku":"MPR4R0.2L15","price":80.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2cbf24a82a031f24e3c81de91dd09e35.jpg?v=1789985489","url":"https:\/\/voomisupply.com\/products\/carmex-mpr4r0-2l15-profile-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
