Hertel E7039032 Square End Mill 0.5in 4 Flute Cobalt Ticn

Product Description

The HERTEL E7039032 is a 4-flute cobalt square end mill designed for general-purpose milling operations in metalworking environments. Built from M42 cobalt high-speed steel, it offers improved heat and wear resistance compared to standard HSS tooling. The TiCN (titanium carbonitride) coating further extends tool life and reduces friction at the cutting edge. With a 0.5 inch cutting diameter, a 1.25 inch length of cut, and a 30-degree right-hand spiral helix, this end mill is suited for side milling, slotting, and profiling applications. It is installed by machinists and toolroom professionals in CNC and manual milling setups.

This end mill is appropriate for use on ferrous metals, alloy steels, and other materials where cobalt tooling provides an advantage over standard HSS. The centercutting geometry allows for direct plunge entry, giving the operator more flexibility during setup. The 0.5 inch shank diameter fits standard R8, ER, and other common collet and end mill holder systems used in vertical milling machines and machining centers. The 3.25 inch overall length suits regular-reach applications without excessive overhang.

Key Features

• M42 cobalt construction for elevated heat resistance and longer tool life in demanding cuts
• TiCN coating reduces friction and wear at the cutting edge
• 4-flute spiral design with 30-degree right-hand helix for efficient chip evacuation
• Centercutting geometry allows direct plunge milling without pre-drilling
• Right-hand cut and right-hand flute configuration for use in standard milling spindles
• Regular length profile minimizes deflection in typical depth-of-cut applications

Compatibility

Designed as a standard 0.5 inch shank square end mill compatible with collet chucks, end mill holders, and similar toolholding systems that accept a 0.5 inch shank diameter in vertical mills and machining centers.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and locked before changing tooling. Seat the shank fully into the collet or holder and tighten to the tool holder manufacturer's specified torque using the appropriate wrench. Inspect the cutting edges for chips or wear before each use and do not run the tool beyond its recommended depth of cut for the material being machined.
