Hertel E599924445 Square End Mill 1/16 in 3 Flute Carbide

Product Description

The HERTEL E599924445 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 1/16-inch cutting diameter, 3-flute geometry, and a 30-degree helix angle, this end mill delivers clean, controlled cuts in tight tolerances. The micrograin carbide substrate provides rigidity and edge retention in demanding materials. Centercutting capability allows both plunge and peripheral milling operations. The uncoated finish suits applications where coating interaction with the workpiece material is a concern. This tool is sized for fine-detail work and is used by machinists in job shop, tool-and-die, and precision manufacturing environments.

This end mill is suited for small-feature milling operations where precise slot cutting, profiling, and plunge entry are required. The 1/8-inch shank diameter fits standard collets in CNC machining centers and manual mills. The 1-1/2-inch overall length keeps the tool compact, reducing deflection during high-precision cuts. Double-end construction maximizes tool life per unit. Typical applications include mold and die work, aerospace component machining, and small-part production runs where tight tolerances and fine surface finish are critical.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• 3-flute geometry balances chip evacuation and cutting surface contact
• 30-degree helix angle for smooth cutting action and reduced chatter
• Centercutting design enables direct plunge entry into workpiece material
• Double-end configuration extends usable tool life
• Uncoated finish suitable for materials sensitive to coated tooling

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with 1/8-inch collets or ER collet systems accepting a 1/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling change procedures. Ensure the spindle is fully stopped and locked before changing tooling. Confirm collet size matches the 1/8-inch shank diameter and that the tool is seated to the correct gauge length before tightening. Avoid exceeding the recommended length of cut to minimize deflection and tool breakage on this small-diameter end mill.
