It features a 1\/4 inch cutter diameter with a 3\/4 inch length of cut, a 40-degree helix angle, and three flutes arranged in a downcut configuration. The bright, uncoated finish suits applications where coating interaction with the workpiece material is a concern. This tool is installed and operated by machinists and CNC programmers working on manual and CNC milling equipment.\u003c\/p\u003e\n\u003cp\u003eThe 873816 is suited for single-end milling operations requiring a right-hand cutting direction. The downcut flute geometry pushes chips downward, which helps produce cleaner top-surface finishes on laminates, composites, and veneered materials. The 1\/4 inch shank diameter fits standard collets and tool holders on both benchtop and production CNC mills. Overall length is 2.5 inches, keeping the tool rigid and reducing deflection during cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eDowncut flute geometry for improved top-surface finish quality\u003c\/li\u003e\n  \u003cli\u003e3 flutes with 40-degree helix angle for balanced chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, single-end configuration\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank diameter fits standard collets and ER-style tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for CNC and manual milling machines accepting a 1\/4 inch shank diameter collet or tool holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC technician. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Seat the shank fully in the collet or tool holder and torque the collet nut to the tool holder manufacturer's specification. Verify runout with a dial indicator before starting the cut to prevent premature wear or tool failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.750 inches (3\/4 inch)\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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Downcut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.31 inches length, 0.51 inches width, 0.51 inches height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 873816\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51731975831858,"sku":"873816","price":104.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d23c6a45b0ebc5b9c3f57c60c4a250cc.jpg?v=1788737491","url":"https:\/\/voomisupply.com\/products\/harvey-tool-873816-square-end-mill-1-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
