Hertel 750362 Square End Mill 5/64 in 4 Flute Solid Carbide

Product Description

The HERTEL 750362 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. Built with four spiral flutes and a 30-degree helix angle, it delivers efficient chip evacuation and smooth cutting action. The mill measures 0.0781 inches (5/64 inch) in diameter with a 3/16-inch length of cut and a 1/8-inch shank diameter, making it well suited for fine detail work and tight-tolerance slots. A titanium nitride (TiN) finish increases surface hardness and extends tool life. The overall length is 1-1/2 inches. Licensed machinists and CNC setup technicians are the primary users of this tool.

This end mill is intended for use in vertical milling machines, CNC machining centers, and manual knee mills where small-diameter, high-precision cuts are required. Its centercutting capability allows direct plunge entry into the workpiece without a pre-drilled hole. Right-hand cut and right-hand flute geometry suit standard spindle rotation. It is appropriate for milling ferrous and non-ferrous metals, plastics, and composites in both production and prototype environments where a compact cutting profile is needed.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• TiN (titanium nitride) coating for increased surface hardness and extended tool life
• 4-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge milling without pilot drilling
• Right-hand cut and right-hand flute for compatibility with standard spindle rotation
• Single-end configuration with 5/64-inch diameter for fine-detail and narrow-slot work

Compatibility

Designed as an OEM-style solid carbide square end mill suitable for use with standard 1/8-inch collets or end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, de-energized state. Secure the 1/8-inch shank in a matching collet or end mill holder and verify runout before beginning a cut. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for the workpiece material. Inspect the cutting edges for wear or chipping before each use and replace the tool if damage is observed.
