Hertel E2080012 Square End Mill 3/16 in Cobalt 2 Flute

Product Description

The HERTEL E2080012 is a cobalt square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Built from M42 cobalt high-speed steel, it provides greater heat and wear resistance than standard M2 HSS tooling. The 3/16-inch cutting diameter pairs with a 3/4-inch length of cut, making it well suited for slotting, profiling, and peripheral milling in tight-clearance areas. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. The uncoated finish allows for easy regrinding. This end mill is installed and used by machinists and tool and die professionals on manual mills and CNC machining centers.

This end mill fits residential and commercial machine shop environments, as well as maintenance and repair operations where precise small-diameter milling is required. The 3/8-inch shank diameter is compatible with standard ER and set-screw style collet chucks. The 2-5/8-inch overall length accommodates typical spindle clearances without requiring extended-reach toolholders. It is classified as a long-length end mill based on its length-of-cut-to-diameter ratio, giving added reach versus stub or standard configurations.

Key Features

• M42 cobalt HSS construction for improved heat resistance over standard HSS
• 30-degree right-hand spiral flute for efficient chip evacuation
• Center-cutting design allows plunge entry without a pre-drilled pilot hole
• 2-flute geometry maximizes chip clearance in slotting applications
• Uncoated finish supports regrinding and rework
• Long-length classification provides added reach in deeper setups

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for machine shop applications requiring a 3/16-inch diameter, 2-flute, cobalt square end mill with a 3/8-inch shank.

Installation Notes

Install in a compatible collet chuck or end mill holder rated for the 3/8-inch shank diameter and confirm runout before cutting. Ensure the spindle and workpiece are fully secured before engaging the cut. Follow shop-standard speeds and feeds for cobalt HSS tooling in the material being machined. Inspect the cutting edges for wear or chipping before each use and remove from service if damage is observed.
