Harvey Tool 789208-C3 Square End Mill 1/8 in 4 Flute Altin

Product Description

The HARVEY TOOL 789208-C3 is a solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. It features a 1/8 inch (0.125 inch) cutting diameter with a 3/16 inch (0.187 inch) length of cut and a 30-degree helix angle. The AlTiN coating provides thermal resistance and extended tool life in demanding cutting conditions. With 4 flutes and a right-hand cutting and flute direction, this end mill delivers efficient chip evacuation and a quality surface finish. It is single-end and center-cutting, making it suitable for both plunge and profile operations. Installed by machinists and tool-and-die professionals, it is compatible with standard CNC and manual milling setups.

This end mill is suited for precision machining in job shops, production facilities, and toolroom environments. The extended reach configuration, with a 1-1/4 inch reach length and 2-1/2 inch overall length, makes it effective for milling in deeper pockets or recessed features where a standard-reach tool would not clear. The 1/8 inch shank diameter fits standard collets and tool holders used across a wide range of vertical machining centers and CNC mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating for elevated thermal protection and longer tool life
• 30-degree helix angle promotes smooth cutting action and efficient chip flow
• Center-cutting design allows direct plunge entry into workpiece material
• Extended reach with 1-1/4 inch reach length for deep pocket and recessed feature access
• Right-hand cut and flute direction compatible with standard spindle rotation

Compatibility

Designed as a direct-fit replacement or upgrade end mill for CNC and manual milling machines accepting a 1/8 inch shank diameter in standard collet or end mill holder configurations.

Installation Notes

Installation is performed by machinists or CNC operators. Ensure the machine spindle is fully stopped and the tool holder is de-energized before inserting or removing the end mill. Use a properly sized collet or shrink-fit holder for the 1/8 inch shank to ensure concentricity and secure retention. Follow applicable shop safety procedures and manufacturer feed-and-speed guidelines for the coating type and workpiece material.
