Hertel E107002401 Square End Mill 3/8 in 2 Flute Hss

Product Description

The HERTEL E107002401 is a 2-flute square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Ground from M7 high speed steel, this tool delivers reliable cutting performance without a coating, making it well suited for applications where re-sharpening is a regular part of toolroom maintenance. The 3/8 inch diameter matches its 3/8 inch shank for straightforward collet or end mill holder setup. A 42-degree helix angle promotes efficient chip evacuation and reduced cutting force. The tool is center-cutting, allowing it to plunge directly into a workpiece. It is sold as a single-end tool in a regular-length configuration.

This end mill fits standard vertical milling machines, knee mills, and CNC machining centers where a 3/8 inch tool holder or collet is available. It is appropriate for slotting, profiling, and peripheral milling in a production or toolroom environment. The bright, uncoated finish makes it a cost-effective choice for shops that run M7 HSS tooling in aluminum, mild steel, and similar workpiece materials. Machinists, tool and die makers, and CNC operators in job shops and manufacturing facilities are the typical end users.

Key Features

• M7 high speed steel construction for toughness in interrupted cuts and general milling
• 42-degree right-hand spiral helix for efficient chip evacuation
• Center-cutting geometry allows direct plunge entry into the workpiece
• Bright/uncoated finish suitable for regrinding and cost-sensitive toolroom use
• Right-hand cutting direction compatible with standard spindle rotation
• Regular length configuration for rigid setups with minimal overhang

Compatibility

Designed as a standard 3/8 inch shank square end mill for use in any end mill holder, collet chuck, or milling arbor accepting a 3/8 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Secure the shank to the full recommended engagement depth in the holder and tighten the collet or set screw to the tool holder specification. Verify runout with a dial indicator before beginning a cut, particularly in precision applications.
