With a 20mm (0.7874 inch) mill diameter and a 4-flute spiral configuration, this head delivers efficient material removal in contour milling, profiling, and finishing operations on hardened and difficult-to-machine materials. The AlTiN finish coating provides thermal resistance and extended tool life under high-speed cutting conditions. The right-hand cutting direction and 40-degree helix angle promote smooth chip evacuation. Connection is via E20 interface, compatible with CoroMill 316 modular bodies.\u003c\/p\u003e\u003cp\u003eThis ball end mill head is suited for use in CNC machining centers in both shop and production environments. It handles contour milling, die and mold work, and complex 3D surface finishing on ferrous and non-ferrous materials. The modular E20 connection allows fast head changes without removing the tool body from the spindle, making it practical for shops running multiple profiles on the same setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20mm ball end diameter for contour and profile milling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-temperature performance and extended tool life\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 40-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting and flute direction\u003c\/li\u003e\n\u003cli\u003eE20 modular connection for use with CoroMill 316 tooling system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the SANDVIK COROMANT CoroMill 316 modular milling system via E20 connection interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified CNC machinist or tooling technician. Ensure the tool body and connection interface are clean and free of chips or debris before threading on the head. Follow the torque and clamping procedures specified in the CoroMill 316 system documentation for the E20 connection. Verify spindle direction and programmed feed rates match the right-hand cutting configuration before running the first pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 20mm (0.7874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 11mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 11mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: E20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroMill 316\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.76 inches x 2.76 inches x 1.26 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.243 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7611778\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51732687192370,"sku":"7611778","price":356.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a839a409702e7f5b25599d16d776825_265b284b-d878-471d-964d-8b038326fb96.jpg?v=1788745733","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7611778-ball-end-mill-head-20mm-e20","provider":"Voomi Supply","version":"1.0","type":"link"}
