Built from micrograin solid carbide, it delivers precise groove geometry in a single pass. The tool features a left-hand cutting direction, a minimum hole diameter of 0.375 inches, and a groove width of 0.095 inches. With an overall length of 2.5 inches and a 3\/8-inch shank diameter, it fits standard toolholders used on lathes and boring setups. Machinists and tool-and-die professionals use this tool when installing internal retaining rings in precision bored components.\u003c\/p\u003e\u003cp\u003eThis grooving tool is suited for interior retaining ring groove applications in production and job-shop environments. It is configured for left-hand cutting, making it appropriate for specific spindle rotation and setup requirements. The full-radius tip geometry produces a clean groove profile matched to standard retaining ring cross-sections. Maximum hole depth capacity is 0.75 inches, with a projection of 0.75 inches and a shank length of 1.75 inches. It is intended for use in CNC lathes, manual lathes, and boring mills where internal groove work is performed on close-tolerance parts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for wear resistance and edge retention in hard materials\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting direction for dedicated left-hand spindle or reverse-rotation setups\u003c\/li\u003e\n\u003cli\u003eFull radius tip geometry sized for retaining ring groove profiles\u003c\/li\u003e\n\u003cli\u003eMinimum bore entry of 0.375 inches with a maximum hole depth of 0.75 inches\u003c\/li\u003e\n\u003cli\u003eGroove width of 0.095 inches for precise ring-seat dimensioning\u003c\/li\u003e\n\u003cli\u003eNo undercut and no adjusting screw  -  fixed geometry for repeatable results\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use interior retaining ring grooving tool for lathes and boring mills accepting a 3\/8-inch shank toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists on lathes or boring mills. Confirm spindle rotation matches the left-hand cutting direction before engaging the workpiece. Secure the shank fully in the toolholder to the recommended engagement depth before taking a cut. Always bring the machine to a full stop before measuring groove dimensions or changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrooving Tool Type\u003c\/strong\u003e: Retaining Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterior\/Exterior\u003c\/strong\u003e: Interior\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Hole Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.095 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Hole Depth\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.75 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\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\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUndercut\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 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: INTERNAL TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 24-1615\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67916973801778,"sku":"24-1615","price":95.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d790f5cd0d73698be959ccebd330284_de28266d-6c00-45b1-a890-0a1616c35f33.jpg?v=1791260424","url":"https:\/\/voomisupply.com\/products\/internal-tool-24-1615-retaining-ring-grooving-tool","provider":"Voomi Supply","version":"1.0","type":"link"}
