Harvey Tool 943210-C3 Square End Mill 5/32 in 4 Flute Altin

Product Description

The HARVEY TOOL 943210-C3 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 5/32-inch (0.1562-inch) cutting diameter and four flutes, this tool delivers clean, accurate cuts in ferrous and non-ferrous materials. The AlTiN coating provides heat resistance and extended tool life at elevated cutting speeds. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is installed and used by machinists and tool-and-die professionals working on CNC machining centers and manual mills.

This end mill suits applications requiring tight-tolerance square-shoulder and slot milling in materials such as hardened steels, stainless steel, and high-temperature alloys where the AlTiN coating performs best. The reduced shank design, with a 1/8-inch shank diameter and 2.5-inch overall length, allows access to tighter workpiece features. The centercutting geometry enables plunge entry as well as conventional peripheral cutting, making it adaptable across a range of milling operations in job shop and production environments.

Key Features

• AlTiN coating for heat resistance and extended tool life in hard and abrasive materials
• Four-flute geometry for improved surface finish and material removal rate
• 30-degree helix angle promotes efficient chip evacuation
• Centercutting capable — supports plunge milling entry
• Solid carbide construction for rigidity and dimensional stability
• Reduced shank (1/8-inch diameter) for access to confined workpiece features

Compatibility

Designed as an OEM-style solid carbide square end mill suitable for use in standard CNC machining center collet systems and manual mill tool holders accepting a 1/8-inch reduced shank diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the tool holder. Verify collet size matches the 1/8-inch shank diameter and that the tool is secured to the manufacturer-recommended clamping depth. Inspect the cutting edges and coating for wear or chipping before each use.
