Hertel E7050008 Square End Mill 1/8 in 2 Flute Cobalt Ticn

Product Description

The HERTEL E7050008 is a double-end cobalt square end mill designed for milling operations in ferrous and difficult-to-machine materials. Built from M42 cobalt high-speed steel, it offers greater heat and wear resistance than standard HSS tooling. The cutting end carries a TiCN coating that further extends tool life by reducing friction and surface wear. With a 0.125-inch cutting diameter, a 0.375-inch length of cut, and a 30-degree spiral helix, this end mill delivers efficient chip evacuation and clean square-shoulder cuts. It is center-cutting, allowing plunge entry into workpiece material without a pre-drilled hole.

This end mill suits job shops, tool rooms, and production machining environments where slotting, profiling, and peripheral milling of steel, stainless, and high-temperature alloys are common tasks. The 0.375-inch shank diameter fits standard ER collet chucks and end mill holders on vertical machining centers and manual knee mills alike. Its regular-length geometry makes it practical for general-purpose work where extended reach is not required. The double-end configuration provides a second usable cutting end, improving cost efficiency per part.

Key Features

• M42 cobalt HSS construction for elevated heat resistance in hard and abrasive materials
• TiCN coating reduces friction and extends cutting edge life
• Center-cutting design permits direct plunge milling without pilot holes
• 30-degree right-hand spiral flute promotes efficient chip evacuation
• Double-end geometry offers two cutting ends per tool
• Right-hand cut and right-hand flute for standard spindle direction

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 0.375-inch end mill holders and ER collet systems used in vertical machining centers, CNC mills, and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or removing the tool from its holder. Ensure the shank is fully engaged in the collet or holder to the recommended grip length before torquing. Inspect the cutting edges and coating for chips or damage before each use, as a compromised edge on cobalt tooling can fracture under cutting load.
