With a 0.25-inch cutting diameter and a 0.875-inch flute length, this tool removes material efficiently while maintaining tight dimensional tolerances. The uncoated solid carbide construction delivers rigidity and wear resistance across a range of workpiece materials. Four flutes provide a balance of chip evacuation and surface finish quality. Overall length is 2.5 inches, and the 0.25-inch shank diameter fits standard toolholders and collet chucks used in CNC and manual milling applications. Machinists and toolroom operators are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is suited for applications requiring a flat-bottomed recess to seat fastener heads, bushings, or mating components flush with or below a workpiece surface. Typical use cases include production machining, job shop work, and precision fixture fabrication. The small cutting diameter makes it appropriate for tight-tolerance counterbore operations where larger tools cannot reach or where workpiece geometry limits tool access. It is intended for use in milling machines and machining centers operating at appropriate speeds and feeds for carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in demanding machining environments\u003c\/li\u003e\n  \u003cli\u003e0.25-inch cutting diameter with 0.875-inch flute length for accurate, flat-bottomed recesses\u003c\/li\u003e\n  \u003cli\u003eFour flutes for efficient chip removal and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e0.25-inch shank diameter compatible with standard collet chucks and toolholders\u003c\/li\u003e\n  \u003cli\u003e2.5-inch overall length provides clearance in typical milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide counterbore for use in CNC machining centers and manual milling machines accepting a 0.25-inch shank diameter toolholder or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists in machine shop environments. Secure the shank fully in the collet or toolholder to the manufacturer-specified engagement depth before operation. Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Select speeds and feeds appropriate for solid carbide tooling and the specific workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eFlute Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 23416\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728569401650,"sku":"23416","price":76.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b509560cc4e4caabc41078ebf7beb7c.jpg?v=1788693460","url":"https:\/\/voomisupply.com\/products\/harvey-tool-23416-solid-carbide-counterbore-0-25in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
