Iscar 5620367 Ball End Mill 0.25 in 4 Flute Solid Carbide

Product Description

The ISCAR 5620367 is a solid carbide ball end mill designed for precision milling in demanding metalworking applications. With a 0.25-inch mill diameter and a 0.75-inch length of cut, this single-end tool delivers accurate ball-nose profiles in a compact form factor. The four-flute design with a 30-degree right-hand helix promotes smooth chip evacuation and stable cutting action. A TiAlN coating provides heat resistance and extends tool life in high-temperature cutting conditions. The submicron carbide grade offers a fine grain structure suited to tight-tolerance work. This tool is installed by machinists and CNC operators in job shop and production environments.

The ISCAR 5620367 is suited for profiling, contouring, and finishing operations on harder workpiece materials. The Series EBI-A-4 designation places this tool within ISCARs ball end mill family optimized for material groups including hardened steels, cast irons, stainless steels, carbon steels, and superalloys, corresponding to ISO material codes H, K, M, P, and S. The 0.25-inch shank diameter fits standard ER collet chucks and end mill holders. The 2.5-inch overall length keeps the tool rigid and minimizes deflection at this diameter.

Key Features

• 0.25-inch ball nose diameter for precise radius profiles and contouring
• TiAlN coating for elevated heat resistance and extended tool life in ferrous and exotic alloys
• 4-flute, 30-degree right-hand spiral helix for efficient chip flow and smooth finish
• Submicron solid carbide grade for dimensional stability and edge retention
• Single-end construction with 0.25-inch shank diameter for direct chuck compatibility
• Series EBI-A-4 — rated for ISO workpiece material groups H, K, M, P, and S

Compatibility

Rated for ISO workpiece material groups H (hardened steels), K (cast irons), M (stainless steels), P (carbon and alloy steels), and S (superalloys and high-temperature alloys). Fits any standard 0.25-inch end mill holder or ER collet chuck.

Installation Notes

This tool is installed by machinists and CNC setup technicians. Secure the 0.25-inch shank in a clean, undamaged collet or end mill holder and verify runout before cutting. Ensure the machine spindle is fully stopped and locked out before changing tooling. Follow the tool manufacturer and machine builder guidelines for feed rate, speed, and depth of cut for the specific workpiece material and operation type.
