Iscar 5621011 Ball End Mill 0.5 in 4 Flute Solid Carbide

Product Description

The ISCAR 5621011 is a solid carbide ball end mill engineered for precision milling in demanding material applications. Featuring a 0.5 inch cutting diameter and a 1 inch length of cut, this 4-flute, single-end tool is built for high-performance metal removal and finishing passes. The TiAlN coating extends tool life in high-heat cutting environments and improves wear resistance at elevated surface speeds. With a 30-degree helix angle and submicron carbide grade, the 5621011 is suited for shops running aggressive parameters on hard and exotic materials. Licensed machinists and CNC programmers typically install and run this tool in vertical and horizontal machining centers.

The 5621011 belongs to the ISCAR EBLI-A-4 series, which is designed for long-reach milling operations requiring a 4.5 inch overall length. Workpiece material codes H, K, M, P, and S indicate suitability for hardened steels, cast irons, stainless steels, carbon steels, and high-temperature alloys. The 0.5 inch shank diameter fits standard ER and side-lock toolholders commonly found in production CNC environments. This is a right-hand cut, right-hand spiral tool with no chipbreaker and no coolant-through capability, making it best suited for flood or external coolant delivery setups.

Key Features

• 0.5 inch ball nose diameter for contour and 3D surface milling
• TiAlN coating for extended tool life in high-temperature cutting
• 4 flutes with 30-degree medium helix for balanced chip evacuation and surface finish
• Submicron solid carbide grade for hardness and toughness in difficult materials
• Long series at 4.5 inches OAL for extended-reach applications
• Right-hand cut and right-hand spiral for standard CNC spindle compatibility

Compatibility

Part of the ISCAR EBLI-A-4 series. Designed for milling workpiece materials designated by primary material codes H, K, M, P, and S, covering hardened steels, cast irons, stainless steels, carbon steels, and high-temperature superalloys. Fits standard 0.5 inch diameter toolholders.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool is secured with appropriate torque in an ER collet, Weldon, or hydraulic toolholder before operation. Verify runout with a dial indicator after tool installation to protect coating integrity and edge geometry. Follow machine manufacturer guidelines and applicable shop safety protocols when handling carbide cutting tools.
