Hertel E2080018 Square End Mill 9/32 in 2 Flute Cobalt

Product Description

The HERTEL E2080018 is a cobalt square end mill designed for general-purpose milling operations in metalworking environments. Built from M42 cobalt high-speed steel, this two-flute tool offers a 9/32-inch (0.2813-inch) cutting diameter and a 1-3/8-inch length of cut. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation and smooth cutting action. The long-series length and center-cutting capability make it suitable for slotting, profiling, and plunge entry cuts. It ships uncoated and ready to run on manual mills, CNC machining centers, and drill presses used in toolroom and production environments. Machinists and tool-and-die technicians are the primary users.

This end mill is well suited for machining ferrous metals, stainless steel, and high-temperature alloys where cobalt tooling outperforms standard HSS. The 3/8-inch shank diameter fits standard ER and R8 collets as well as side-lock holders commonly found in job shops and production cells. The long-series overall length of 3-1/8 inches provides added reach for deeper pockets or fixtures that limit tool access. Its right-hand cut and right-hand flute configuration is the standard orientation for conventional vertical milling operations.

Key Features

• M42 cobalt construction for heat resistance and edge retention in tough materials
• 9/32-inch cutting diameter with 1-3/8-inch length of cut
• Two flutes with 30-degree right-hand spiral for efficient chip removal
• Center-cutting design allows direct plunge entry without a pilot hole
• Long-series 3-1/8-inch overall length for extended reach applications
• Uncoated finish compatible with most cutting fluids and lubricants

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for 3/8-inch collet chucks, side-lock end mill holders, and R8 collet systems used in standard vertical milling operations.

Installation Notes

A licensed machinist or qualified toolroom technician should install and operate this end mill. Secure the shank fully within the collet or holder to the recommended engagement depth before running the spindle. Ensure the machine spindle is fully stopped and locked out before changing tooling. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and cut depth.
