Harvey Tool 890328-C3 Thread Mill M5x0.80 4 Flute Carbide

Product Description

The HARVEY TOOL 890328-C3 is a single profile thread mill designed for cutting M5 x 0.80 threads in both internal and external applications. Built from solid carbide and finished with an AlTiN coating, this tool delivers heat resistance and extended tool life in demanding machining environments. It features 4 flutes and a cutting diameter of 4 inches, with an overall length of 1.9685 inches. The AlTiN coating reduces friction and improves performance in ferrous and hardened materials. This tool is used by machinists and CNC programmers requiring precise metric thread profiles in a single-pass or helical interpolation setup.

The 890328-C3 is suited for CNC machining centers performing internal and external M5 x 0.80 thread milling operations. Its compact overall length of 1.9685 inches and neck diameter of 2.4 inches make it appropriate for close-tolerance thread work in steel, stainless, and similar materials. The single profile design allows one tool to cut a full thread form, reducing tool changes and simplifying programming for both through and blind hole applications in production and job shop environments.

Key Features

• Cuts M5 x 0.80 metric threads in both internal and external configurations
• Solid carbide construction for rigidity and dimensional stability
• AlTiN coating for high-temperature resistance and extended tool life
• 4-flute geometry for efficient chip evacuation and surface finish
• Single profile design reduces tool inventory and simplifies CNC programming
• Neck length of 0.2756 inches provides clearance in tight-access thread locations

Compatibility

Designed as an OEM-style replacement and standard tooling selection for CNC machining centers requiring M5 x 0.80 single profile thread milling in internal and external applications.

Installation Notes

Installation and operation should be performed by qualified CNC machinists familiar with helical interpolation thread milling routines. Secure the tool in an appropriate collet or end mill holder and verify runout before cutting. Power down the machine and follow lockout/tagout procedures when changing tooling. Refer to the machine tool manufacturer guidelines and applicable shop safety standards when programming feeds and speeds for carbide thread mills.
