Hertel E2110008 Ball End Mill 1/8 in 2 Flute Cobalt

Product Description

The HERTEL E2110008 is a cobalt ball end mill designed for precision milling operations in ferrous and high-temperature alloy materials. Built from M42 cobalt high-speed steel, this single-end tool features a 1/8 inch cutting diameter and a 2-flute spiral configuration with a 30-degree helix angle. The bright, uncoated finish makes it well-suited for applications where coating adhesion is not required or where re-sharpening is anticipated. Machinists and toolroom technicians rely on this geometry for contouring, profiling, and slotting passes in both manual and CNC milling setups.

This end mill fits standard milling applications in job shops, production machining, and maintenance toolrooms. The 3/8 inch length of cut and 3/8 inch shank diameter are suited for light-to-moderate depth passes in steel, stainless, cast iron, and similar materials. The right-hand cutting and right-hand flute direction are compatible with conventional CNC machining centers and manual knee mills running standard spindle rotation. The standard length designation confirms this is not an extended-reach tool, making it appropriate for setups with minimal clearance requirements.

Key Features

• M42 cobalt high-speed steel construction for heat and wear resistance in ferrous materials
• Ball end geometry enables contouring, 3D profiling, and radius floor finishing
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Bright, uncoated finish allows for re-sharpening and suits dry or flood coolant use
• Right-hand cut and right-hand spiral for standard CNC and manual mill spindle rotation
• Single-end design with 2-flute configuration balances chip clearance and cutting edge strength

Compatibility

Designed as an OEM-style replacement or direct substitute for standard 1/8 inch shank ball end mills in CNC machining centers and manual milling machines accepting 3/8 inch collets or end mill holders.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully powered down and at a complete stop before changing tooling. Secure the 3/8 inch shank in a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Verify runout with an indicator before beginning a cut, as excessive runout accelerates wear on small-diameter tooling.
