Hertel 750454 Square End Mill 11/32 in 4 Flute Altin

Product Description

The HERTEL 750454 is a solid carbide square end mill designed for precision material removal in ferrous and non-ferrous machining applications. With a 0.3438-inch (11/32 inches) cutting diameter, 4-flute geometry, and a 30-degree right-hand helix, this end mill delivers efficient chip evacuation and stable cutting performance. The AlTiN coating provides thermal resistance and extended tool life in high-heat machining environments. It is a single-end, centercutting tool, meaning it can be used for plunge cuts as well as peripheral and slot milling operations. This tool is suited for machinists and tool-and-die professionals running CNC mills or manual milling machines.

This end mill fits standard milling applications in machine shops, production environments, and toolroom settings. The 3/8-inch shank diameter fits common collet systems and end mill holders found on vertical milling centers and CNC machining centers. The regular length profile and 7/8-inch length of cut make it appropriate for shallow-to-medium depth profiling, slotting, and contouring passes. The micrograin carbide substrate supports use in harder workpiece materials where high-speed steel tooling would wear prematurely.

Key Features

• 11/32 inches (0.3438 inches) cutting diameter with 7/8 inches length of cut
• 4-flute spiral flute design for balanced cutting and chip flow
• AlTiN coating for heat resistance and extended tool life in demanding cuts
• 30-degree right-hand helix with right-hand cutting direction
• Centercutting capability allows direct plunge entry into workpiece
• Micrograin solid carbide substrate for edge retention in hard materials

Compatibility

Designed for use with standard 3/8-inch collets, end mill holders, and shrink-fit toolholders on CNC machining centers and manual vertical mills. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before inserting the end mill. Secure the shank to the full recommended engagement depth in the collet or holder to minimize runout. Follow the tool manufacturer and machine OEM guidelines for appropriate feed rates and speeds based on workpiece material and depth of cut.
