Hertel 750320 Square End Mill 3/8 in 2 Flute Solid Carbide

Product Description

The HERTEL 750320 is a solid carbide square end mill designed for precision material removal in milling operations. Built with a 0.375-inch cutting diameter and a 1-inch length of cut, it handles slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The 3/8-inch shank diameter fits standard toolholders, and the 2.5-inch overall length suits typical CNC and manual milling setups. A titanium nitride (TiN) coating reduces friction and extends tool life. With a 30-degree helix angle and spiral flute geometry, the tool promotes efficient chip evacuation and stable cutting performance. This end mill is used by machinists and tool-and-die professionals in production and job-shop environments.

This end mill is suited for general-purpose milling applications including side milling, slotting, and light profiling. The centercutting design allows plunge entry into the workpiece, expanding its use across a range of operations without a pre-drilled start hole. The right-hand cut configuration is standard for conventional CNC machining centers and manual knee mills. It is appropriate for cutting aluminum, steel, cast iron, and similar materials at appropriate feeds and speeds for the material and machine setup.

Key Features

• 0.375-inch cutting diameter with 1-inch length of cut for versatile depth capability
• Solid carbide construction provides rigidity and wear resistance
• TiN coating reduces friction and extends cutting life
• 30-degree helix spiral flute promotes efficient chip evacuation
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut, compatible with standard CNC and manual milling setups

Compatibility

Designed as a standard-shank replacement end mill for use in 3/8-inch collets, end mill holders, and milling chucks on CNC machining centers and manual knee mills.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state. Ensure the toolholder and collet are clean and free of chips before seating the shank. Verify runout with a dial indicator after clamping to confirm proper seating. Follow machine-specific torque procedures for the toolholder type in use.
