Manufactured from submicron-grade solid carbide, this tool delivers consistent cutting performance and extended tool life in demanding machining environments. It features a 3\/8-inch shank diameter, a 0.0400-inch groove width, and a projection of 0.1100 inches, making it suited for tight-tolerance internal groove work. Machinists and tool-and-die professionals install this tool when precise, repeatable groove geometry is required in bore finishing or undercut operations.\u003c\/p\u003e\n\u003cp\u003eThis grooving tool is intended for use in internal bore grooving applications where a full radius profile is required. It fits toolholders with a 3\/8-inch bore and accommodates holes with a minimum diameter of 0.3750 inches and a maximum depth of 0.2500 inches. Typical applications include groove cutting in ferrous and non-ferrous workpieces on manual or CNC turning centers. It is a single-piece solid carbide construction, appropriate for production and jobshop environments where tool rigidity and edge retention are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFull radius grooving profile for precise internal groove geometry\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for extended edge life\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter for standard toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003e0.0400-inch groove width for tight-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eMaximum hole depth of 0.2500 inches suits shallow internal groove work\u003c\/li\u003e\n  \u003cli\u003eOverall length of 2.5 inches provides stable reach in bore operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 3\/8-inch shank internal grooving toolholders requiring a full radius profile with a 0.0400-inch groove width.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists on CNC or manual turning equipment. Power down and lock out the machine spindle before seating or removing the tool. Ensure the shank is fully seated and clamped to the specified toolholder torque per the toolholder manufacturer guidelines. Verify runout and projection before beginning a production run.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.0400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hole Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Hole Depth\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.1100 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\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1875 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ACC-GF039-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732020724018,"sku":"ACC-GF039-4","price":91.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/676b09a00821f235814e32cfb62d30e6.jpg?v=1788738221","url":"https:\/\/voomisupply.com\/products\/accupro-acc-gf039-4-full-radius-grooving-tool-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
