Hertel E5022004 Square End Mill 1/16 in 2 Flute Carbide

Product Description

The HERTEL E5022004 is a double-end square end mill designed for precision milling in metalworking and machining applications. Built from micrograin solid carbide, this tool delivers consistent edge integrity and wear resistance in demanding cutting operations. It features a 1/16 inch (0.0625 inch) mill diameter, a 1/8 inch length of cut, and a 30-degree right-hand spiral helix for efficient chip evacuation. With two flutes and a bright/uncoated finish, it is well suited for high-speed passes in non-ferrous metals, plastics, and other materials where coating buildup is not a concern. Machinists and CNC operators working on close-tolerance features will find the double-end configuration adds useful tool life per holder setup.

This end mill is intended for use in CNC machining centers, manual mills, and tool-and-die work where small-diameter precision cutting is required. Its 1/8 inch shank diameter suits standard collet systems commonly found in benchtop and full-size vertical mills. The centercutting geometry allows direct plunge entry as well as conventional peripheral and slot milling. Applications include small slot cutting, profiling, and detail work in prototype shops, production environments, and toolroom settings.

Key Features

• Micrograin solid carbide construction for improved hardness and edge retention
• Double-end design extends usable tool life per piece
• 30-degree right-hand helix promotes smooth chip flow and reduced cutting forces
• Centercutting capable — supports plunge, slot, and peripheral milling
• Bright/uncoated finish suitable for non-ferrous metals and plastics
• Two-flute configuration provides adequate chip clearance at small diameters

Compatibility

Designed as an OEM-style replacement or direct-use small-diameter end mill for standard 1/8 inch collet or tool-holder systems on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with tool-holding procedures. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the tool-holder manufacturer's specification. Inspect the cutting edges for chips or damage before each use, as micrograin carbide is rigid but brittle under lateral shock loads.
