Iscar 3398310 Ball End Mill 0.5in 4 Flute Solid Carbide

Product Description

The ISCAR 3398310 is a solid carbide ball end mill engineered for precision milling in demanding metalworking applications. With a 0.5 inch diameter and 4-flute geometry, this single-end tool delivers efficient chip evacuation and a quality surface finish on contoured and 3D-profiled workpieces. The 38-degree right-hand helix promotes smooth cutting action and reduces vibration during aggressive passes. A TiAlCN coating provides thermal resistance and hardness, extending tool life in ferrous and hardened materials. Licensed machinists and CNC programmers running production or job-shop operations will find this tool ready for high-speed milling routines where tool rigidity and coating durability matter.

This end mill is suited for contour milling, profiling, and finishing operations on machining centers handling steel, stainless steel, cast iron, and similar materials. The 1.5 inch length of cut accommodates moderate-depth passes on complex geometries, while the 0.5 inch shank fits standard ER and Weldon-style toolholders common in production CNC setups. The variable index design helps disrupt harmonic vibration, making it a practical choice for harder materials where chatter control is critical.

Key Features

• 0.5 inch ball end diameter for accurate 3D contouring and radius profiling
• 4-flute spiral flute design for efficient material removal and improved surface finish
• TiAlCN coating for elevated temperature resistance and extended tool life
• 38-degree right-hand helix for smooth cutting action and reduced chatter
• Variable index flute spacing to disrupt harmonic vibration during cutting
• Single-end solid carbide construction for rigidity and dimensional accuracy

Compatibility

Designed as an OEM-style replacement and production cutting tool for CNC machining centers accepting a 0.5 inch shank diameter. Also listed under manufacturers catalog number EBI-4 500-1.5CVF4 within the ISCAR Flash Solid series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC tooling technician with the spindle fully stopped and the machine in a safe, locked-out state. Seat the 0.5 inch shank fully and concentrically in the toolholder before tightening to prevent runout. Verify tool projection, spindle speed, and feed rate settings against the material-specific cutting data before starting the program. Inspect the cutting edges and coating condition regularly and replace the tool at first signs of wear to maintain dimensional accuracy and part quality.
