Hertel E2033016 Square End Mill 2 Flute Cobalt

Product Description

The HERTEL E2033016 is a cobalt square end mill designed for metal removal in milling operations across a wide range of ferrous and difficult-to-machine materials. It features a 0.25 inch diameter cutting edge, a 0.625 inch length of cut, and a 3/8 inch shank diameter. The cobalt M42 substrate provides heat resistance and edge retention at elevated cutting temperatures. With a 30-degree spiral helix and right-hand cut geometry, this end mill delivers efficient chip evacuation and smooth surface finishes. Licensed machinists and tool-and-die professionals rely on this style of end mill for slotting, profiling, and peripheral milling on manual and CNC machines alike.

This end mill is suited for job shop, production, and toolroom applications where cobalt tooling is preferred over high-speed steel for improved wear resistance. The centercutting design allows direct plunge entry into the workpiece without a pre-drilled pilot hole, simplifying setups. The 3-1/16 inch overall length and 1.5 inch reach length accommodate standard toolholders and collet chucks on vertical and horizontal milling machines. Extended reach geometry supports deeper cavity work where standard-length tooling cannot reach.

Key Features

• M42 cobalt substrate for superior heat and wear resistance versus standard HSS
• 30-degree helix spiral flute for efficient chip evacuation and reduced cutting forces
• Centercutting geometry allows direct plunge milling without a pre-drilled hole
• Right-hand cut and right-hand flute configuration compatible with standard milling spindles
• 3/8 inch shank diameter fits standard ER collets and side-lock toolholders
• Uncoated finish suitable for use with cutting fluid on ferrous materials

Compatibility

Designed as an OEM-style replacement or direct-application cobalt square end mill for use in standard milling machine toolholders and collet systems accepting a 3/8 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the milling spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention mechanism to the toolholder specification before initiating a cut. Inspect the cutting edges for chips or wear before each use and replace tooling that shows visible damage to prevent workpiece defects or tool breakage.
