With a minimum bore diameter of 0.16 inches and a maximum bore depth of 0.39 inches, this bar handles tight-bore applications where reach and rigidity are critical. The bright finish coating reduces built-up edge in non-ferrous and ferrous materials. A 0.008-inch corner radius provides a controlled profile geometry suitable for precision internal contour work. Machinists and toolroom technicians install this bar in applications requiring consistent, repeatable results in small-diameter bores.\u003c\/p\u003e\n\u003cp\u003eThis profile boring bar is suited for precision internal profiling and threading in small-bore workpieces on CNC turning equipment. The right-hand cutting direction makes it compatible with standard spindle rotation on most turning centers. The 4 mm shank diameter allows it to fit compact boring holders and modular tooling systems used in watchmaking, medical device machining, and other tight-tolerance industries. It is appropriate for shops running high-precision parts where bore diameter and surface finish must meet close tolerances.\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\u003eMinimum bore diameter of 0.16 inches enables access to very tight internal features\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 0.39 inches with a 2.0-inch overall length\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard spindle rotation compatibility\u003c\/li\u003e\n  \u003cli\u003e0.008-inch corner radius for controlled internal profile geometry\u003c\/li\u003e\n  \u003cli\u003eBright finish coating for reduced friction and cleaner chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling addition for CNC lathes and turning centers accepting a 4 mm shank boring bar holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the boring bar from its holder. Confirm the shank is fully seated and clamped to the tool holder manufacturer's specifications before initiating a cutting cycle. Do not exceed the maximum bore depth of 0.39 inches, as overreach beyond the rated depth can cause deflection and tool breakage.\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: 0.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 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: MPR4R0.2L10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52027936506162,"sku":"MPR4R0.2L10","price":79.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b200babbb7567b7407e6237d4602227.jpg?v=1790017422","url":"https:\/\/voomisupply.com\/products\/carmex-mpr4r0-2l10-profile-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
