Hertel 750466 Square End Mill 7/32 in 4 Flute Solid Carbide

Product Description

The HERTEL 750466 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 7/32 inch (0.2188 inch) cutting diameter and a 4-flute spiral design, it delivers clean, accurate cuts in both roughing and finishing applications. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. A titanium nitride (TiN) finish adds surface hardness and heat resistance, extending tool life in production environments. This end mill is centercutting, enabling direct plunge entry into workpieces. It is typically installed and operated by machinists and CNC programmers in job shop, manufacturing, and toolroom settings.

This end mill suits vertical and horizontal milling machines, CNC machining centers, and manual mills. It is well suited for slot milling, profiling, and contouring in materials such as aluminum, steel, and cast iron. The 5/8 inch length of cut and 1/4 inch shank diameter make it appropriate for short-reach applications requiring tight tolerances. The right-hand cut and right-hand flute configuration matches the standard spindle direction on most machines.

Key Features

• Solid carbide construction for rigidity and wear resistance
• TiN coating increases surface hardness and extends tool life
• 30-degree helix angle promotes efficient chip evacuation
• Centercutting design allows direct plunge milling
• 4-flute spiral configuration suited for finishing cuts
• Right-hand cut and right-hand flute for standard spindle compatibility

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/4 inch collets and end mill holders on CNC and manual milling machines.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before inserting or removing the end mill. Secure the 1/4 inch shank in a properly sized collet or end mill holder, tightening to the tool holder manufacturer specification. Verify runout with a dial indicator before initiating a cut to avoid premature tool wear or workpiece damage.
