Hertel E5022008 Square End Mill 1/8 in 2 Flute Solid Carbide

Product Description

The HERTEL E5022008 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 0.125 inch (1/8 inch) mill diameter and a 0.250 inch length of cut, this tool delivers clean, accurate square-shoulder profiles at tight tolerances. The two-flute, center-cutting geometry allows plunge entry as well as conventional peripheral milling. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the hardness and edge retention needed for demanding machining applications. The uncoated finish suits a wide range of materials where coating interaction could be a concern.

This end mill is used in CNC machining centers, manual knee mills, and high-speed spindle applications where small-diameter precision work is required. The double-end design delivers two usable cutting ends, extending tool life per unit. Typical applications include slot milling, profiling, and step milling in aluminum, brass, steel, and plastics. The right-hand cut orientation is standard for conventional spindle rotation. This tool is commonly installed by machinists, tooling technicians, and CNC operators working in production shops, job shops, and maintenance environments.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• Center-cutting design allows direct plunge entry without a pre-drilled hole
• 30-degree helix angle promotes efficient chip flow and reduced cutting forces
• Double-end configuration provides two cutting ends per tool
• Uncoated finish suitable for a broad range of workpiece materials
• Right-hand cut, standard rotation compatible with conventional machining setups

Compatibility

Designed as an OEM-style replacement or standard tooling option for 1/8 inch collet or end mill holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Use a calibrated collet or end mill holder sized to the 0.125 inch shank diameter and torque the retention mechanism per the holder manufacturer specifications. Confirm tool runout with a dial indicator before beginning a cut to protect both the workpiece and the cutting edge.
