Built from micrograin carbide, it delivers consistent cutting performance and edge retention in ferrous and non-ferrous materials. The tool features a 4 mm shank diameter and a 0.040-inch groove width, making it well suited for tight-tolerance grooving operations on CNC lathes and turning centers. Machinists and toolroom operators working in production or job-shop environments rely on this type of tool for clean, repeatable internal grooves in small-diameter bores.\u003c\/p\u003e\u003cp\u003eThis grooving tool is intended for internal grooving operations where bore access is limited. With a minimum hole diameter of 0.160 inches and a maximum hole depth of 0.390 inches, it is appropriate for small-bore grooving on turned components. It is commonly used in precision machining of hydraulic fittings, valve bodies, and other small-diameter parts requiring internal relief or snap-ring grooves. The 2.000-inch overall length keeps the tool compact for use in confined setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for extended tool life and sharp edge retention\u003c\/li\u003e\n\u003cli\u003e4 mm shank diameter for compatibility with standard small-bore toolholders\u003c\/li\u003e\n\u003cli\u003e0.040-inch groove width for precise internal grooving\u003c\/li\u003e\n\u003cli\u003eMinimum bore entry of 0.160 inches suits small-diameter workpieces\u003c\/li\u003e\n\u003cli\u003eMaximum hole depth of 0.390 inches covers typical internal groove reach requirements\u003c\/li\u003e\n\u003cli\u003eCompact 2.000-inch overall length reduces overhang and vibration risk\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit grooving insert tool for standard 4 mm shank internal grooving toolholders used on CNC lathes and turning centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before mounting or removing the tool. Secure the shank firmly in the toolholder to the manufacturer-specified clamping torque and verify tool runout before cutting. Follow applicable shop safety procedures and machine manufacturer guidelines when setting tool offsets and cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width (Projection)\u003c\/strong\u003e: 0.040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Hole Diameter\u003c\/strong\u003e: 0.160 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Hole Depth\u003c\/strong\u003e: 0.390 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.017 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MGR4B1.0L10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51972372070706,"sku":"MGR4B1.0L10","price":70.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78d59547f759a6b7f943c7cdd525c9c9.jpg?v=1789967056","url":"https:\/\/voomisupply.com\/products\/carmex-mgr4b1-0l10-solid-carbide-grooving-tool","provider":"Voomi Supply","version":"1.0","type":"link"}
