Hertel E599924688 Square End Mill 0.3937 in 2 Flute Carbide

Product Description

The HERTEL E599924688 is a solid carbide square end mill designed for precision material removal in milling operations. With a 0.3937-inch (10 mm) mill diameter and a 0.8661-inch (22 mm) length of cut, this tool delivers consistent performance in a regular-length format. The 2-flute geometry and 30-degree helix angle promote efficient chip evacuation, making it well suited for slotting, profiling, and plunge cutting. The centercutting design allows direct axial entry into workpiece material. Micrograin carbide construction provides the hardness and wear resistance required for demanding cutting conditions across a range of materials.

This end mill is intended for use in CNC machining centers, knee mills, and similar machine tool setups where a right-hand cut, uncoated solid carbide tool is appropriate. It is suited for shops and toolrooms handling ferrous and non-ferrous materials where tight tolerances and consistent tool geometry are priorities. The uncoated finish makes it a cost-effective choice for applications where specialized coatings are not required or where regrinding is planned.

Key Features

• 0.3937-inch (10 mm) mill diameter with matching 10 mm shank diameter
• 0.8661-inch (22 mm) length of cut in the regular-length category
• 2-flute design with 30-degree helix for effective chip clearance
• Centercutting geometry allows plunge entry without a pre-drilled hole
• Right-hand cut, uncoated micrograin solid carbide construction
• No chipbreaker, no variable helix, no variable index for predictable, consistent performance

Compatibility

Designed as a standard shank solid carbide square end mill compatible with ER collet chucks, shrink-fit holders, and side-lock arbors accepting a 10 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool is clamped to the holder manufacturer's recommended pull-out resistance before operation. Confirm runout at the cutting edge with a dial indicator before beginning a cut. Follow the end mill manufacturer's recommended speeds and feeds for the workpiece material and do not exceed the tool's rated length of cut.
