Built from micrograin solid carbide, it delivers consistent edge retention and dimensional accuracy in precision machining applications. The tool features a full radius profile and right-hand cutting direction, making it suited for CNC lathes and manual turning centers where controlled internal groove geometry is required. With a minimum hole diameter of 0.125 inches and an overall length of 3.0 inches, it reaches into tight bore entries while maintaining rigidity. Machinists and tool-and-die professionals install this tool in standard shank holders for interior grooving passes on ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003cp\u003eThis grooving tool is designed for interior applications where a small bore entry is involved. It is commonly used in precision component manufacturing, hydraulic valve bodies, pneumatic fittings, and similar workpieces requiring a clean internal groove or undercut relief. The 1\/16-inch shank diameter and 1.375-inch shank length suit micro-bore toolholders found in Swiss-style and small-part turning setups. The 0.625-inch maximum hole depth and 0.625-inch projection define the effective reach for groove placement within the bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003eFull radius grooving profile for clean, consistent groove geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard lathe spindle rotation\u003c\/li\u003e\n  \u003cli\u003eMinimum bore entry of 0.125 inches enables work in very small diameter holes\u003c\/li\u003e\n  \u003cli\u003eInterior grooving application with no undercut geometry\u003c\/li\u003e\n  \u003cli\u003eCompact 1\/16-inch shank fits micro-bore and Swiss-type toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit interior grooving tool for 1\/16-inch shank micro-bore toolholders used in small-part CNC turning and Swiss-style lathe setups where a minimum bore diameter of 0.125 inches is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist. Secure the shank fully in a compatible toolholder and confirm proper projection before taking a grooving pass. Power down and lock out the spindle before tool changes. Follow shop-standard feeds and speeds for solid carbide tooling in the workpiece material being cut; do not exceed the 0.625-inch maximum hole depth to avoid tool deflection or breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrooving Tool Type\u003c\/strong\u003e: Interior Grooving\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hole Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Hole Depth\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 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\u003eUndercut\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: INTERNAL TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20-1215\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67910509592882,"sku":"20-1215","price":49.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95e81264d86d05eb78f58c09be1ea7ab_f3dcdb86-6af2-40a6-bc83-1e2cae513cae.jpg?v=1791198430","url":"https:\/\/voomisupply.com\/products\/internal-tool-20-1215-interior-grooving-tool-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
