Hertel E299914083 Square End Mill 7/16 in 2 Flute Cobalt

Product Description

The HERTEL E299914083 is a 2-flute cobalt square end mill designed for general-purpose milling operations in metalworking applications. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting ferrous and non-ferrous metals. The cutting diameter measures 7/16 inches with a 7/16-inch length of cut and a 3/8-inch shank diameter. Overall length is 2-7/16 inches. The 30-degree spiral flute geometry promotes efficient chip evacuation, and the centercutting design allows plunge entry into workpieces. This tool is installed and used by machinists and CNC operators in production and job-shop environments.

This end mill is suited for slotting, profiling, and light pocketing operations on steel, cast iron, stainless steel, and similar materials. The right-hand cut and right-hand flute configuration is standard for conventional milling setups. The uncoated finish makes it a practical choice for applications where coolant is used or where regrinding after wear is planned. It fits standard 3/8-inch collets and end mill holders found on vertical mills, CNC machining centers, and manual knee mills.

Key Features

• M42 cobalt HSS construction provides elevated heat and wear resistance versus standard M2 HSS
• Centercutting design allows direct plunge milling without pre-drilled entry
• 30-degree helix angle promotes smooth cutting action and effective chip evacuation
• 2-flute geometry offers clearance for chip flow in slotting and pocket entry cuts
• Right-hand cut and right-hand flute for standard spindle rotation setups
• Uncoated finish compatible with conventional flood coolant use and regrind programs

Compatibility

Designed as a standard 3/8-inch shank square end mill compatible with 3/8-inch collets, end mill holders, and Weldon-style tool holders on vertical milling machines and CNC machining centers.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention mechanism according to the machine tool manufacturer specifications. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and reduces dimensional accuracy.
