Hertel 750382 Square End Mill 1/4 in 4 Flute Carbide Tin

Product Description

The HERTEL 750382 is a solid carbide square end mill designed for precision milling in metal, composite, and hard material applications. Built with a 4-flute, right-hand spiral configuration and a 30-degree helix angle, this single-end tool delivers efficient chip evacuation and a clean finish on ferrous and non-ferrous workpieces. The micrograin carbide substrate provides wear resistance and edge stability under demanding cutting conditions. A titanium nitride (TiN) coating further extends tool life by reducing friction and heat buildup at the cutting zone. This end mill is used by machinists and tooling professionals in production shop and job shop environments.

This end mill suits applications requiring tight tolerances in slotting, profiling, and peripheral milling operations. The centercutting geometry allows for plunge entry into the workpiece. With a 1/4-inch shank diameter, it fits standard collet chucks and milling tool holders common to vertical machining centers, knee mills, and CNC routers. The right-hand cutting direction is compatible with conventional and climb milling setups.

Key Features

• Micrograin solid carbide construction for rigidity and long tool life
• TiN coating reduces friction and extends cutting edge durability
• 30-degree helix angle promotes smooth cutting action and chip flow
• Centercutting design allows direct plunge milling
• 4-flute spiral geometry for improved surface finish on finish passes
• Single-end configuration with right-hand flute and cutting direction

Compatibility

Designed as an OEM-style replacement or direct-use end mill for 1/4-inch collet and tool holder systems used in standard CNC and manual milling machine setups.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism to the tool holder specification. Verify runout with a dial indicator before beginning a cut, particularly for finish milling operations.
