It operates with a right-hand cutting direction and accepts holes as small as 0.25 inches in minimum diameter. Built from micrograin solid carbide, this tool delivers consistent edge retention and dimensional accuracy in precision machining applications. The full-radius geometry produces a clean, radiused groove profile in a single pass. With an overall length of 3.0 inches and a shank diameter of 0.25 inches, it fits standard collet-style and chuck-style toolholders used on lathes and boring machines.\u003c\/p\u003e\u003cp\u003eThis grooving tool is suited for interior groove operations on small-diameter bores in production and job-shop environments. Machinists, toolroom technicians, and CNC lathe operators use this type of tool when cutting snap-ring grooves, oil grooves, or relief channels inside bored workpieces. The 0.625-inch projection and 0.625-inch maximum hole depth rating make it well matched to shallow interior groove applications where reach and rigidity both matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for extended tool life and consistent edge sharpness\u003c\/li\u003e\n\u003cli\u003eFull-radius cutting geometry produces a radiused groove profile in one pass\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard lathe rotation\u003c\/li\u003e\n\u003cli\u003e0.25-inch minimum bore diameter allows use in small-diameter interior applications\u003c\/li\u003e\n\u003cli\u003e0.625-inch maximum hole depth and 0.625-inch projection suit shallow interior groove work\u003c\/li\u003e\n\u003cli\u003eNo undercut geometry and no tool-bit adjusting screw for straightforward, fixed-geometry setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style interior grooving tool for use in standard 0.25-inch shank toolholders on CNC and manual lathes capable of interior boring and grooving operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Secure the shank fully in the toolholder collet or boring bar seat before initiating any spindle rotation. Verify that the tool projection does not exceed the rated 0.625-inch depth to avoid tool deflection or breakage. Power down and lock out the machine before changing or adjusting any cutting tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMinimum Hole Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.875 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\u003eProjection\u003c\/strong\u003e: 0.625 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\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\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\u003eInterior\/Exterior\u003c\/strong\u003e: Interior\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 20-1315\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67909780701490,"sku":"20-1315","price":58.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95e81264d86d05eb78f58c09be1ea7ab_88e0a7cb-8632-49ab-b401-7e5ba60bd2fe.jpg?v=1791192337","url":"https:\/\/voomisupply.com\/products\/internal-tool-20-1315-interior-grooving-tool-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
