With a 0.25 inch cutting diameter and a 1.5 inch length of cut, this single-end mill handles contouring, slotting, and profiling passes where a ball nose geometry is required. The 4-flute configuration provides a balance of chip clearance and cutting edge strength, while the TiCN (titanium carbonitride) coating improves hardness and wear resistance compared to uncoated carbide. This tool is typically installed and used by machinists and tool-and-die technicians in CNC machining centers and manual milling applications.\u003c\/p\u003e\u003cp\u003eThis ball end mill is suited for milling ferrous and non-ferrous metals including alloy steels, cast iron, aluminum alloys, and hardened materials where a TiCN coating provides adequate lubricity and heat resistance. With a 0.25 inch shank diameter matching the cutting diameter, it fits standard ER collet chucks, end mill holders, and shrink-fit tooling systems common in production and job-shop environments. The right-hand cutting direction and right-hand flute spiral make it compatible with conventional CNC spindle rotation on vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBall nose geometry for 3D contouring, ramp milling, and profiling cuts\u003c\/li\u003e\n\u003cli\u003e4-flute design balances chip evacuation with edge rigidity for finish passes\u003c\/li\u003e\n\u003cli\u003eTiCN coating provides increased surface hardness and extended tool life over uncoated carbide\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability at higher feed rates\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with right-hand cut and right-hand flute spiral\u003c\/li\u003e\n\u003cli\u003e0.25 inch shank fits standard collet and end mill holder tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 0.25 inch shank ball end mill compatible with ER collets, end mill holders, and other toolholding systems accepting a 0.25 inch round shank across vertical and horizontal CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify runout with a dial indicator after seating in the collet or holder before beginning a cut. Follow the tool manufacturer and machine builder guidelines for appropriate speeds, feeds, and depth-of-cut parameters for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EG062016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735577887026,"sku":"EG062016","price":67.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/508e848f1fe0dbcfc24e143951216f0f.jpg?v=1788773092","url":"https:\/\/voomisupply.com\/products\/hertel-eg062016-ball-end-mill-0-25-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
