Hertel E199913328 Square End Mill 5/32 in 4 Flute Hss

Product Description

The HERTEL E199913328 is a 4-flute, single-end square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Built from M7 high speed steel with a bright uncoated finish, this tool is suited for slotting, profiling, and peripheral milling on ferrous and non-ferrous materials. The mill diameter is 0.1563 inches (5/32 inches) with a 7/16-inch length of cut, making it appropriate for light-duty finishing and moderate material removal in confined geometries. The 30-degree helix angle promotes smooth chip evacuation and stable cutting action. Machinists and tool room operators working on manual mills or CNC machining centers are the primary users of this tool.

This end mill is suited for use in job shops, tool rooms, and production machining environments where small-diameter, close-tolerance work is required. Its 3/8-inch shank diameter fits standard collets and end mill holders commonly found on vertical milling machines and CNC machining centers. The regular-length configuration and bright finish make it a practical choice for general steel and aluminum milling where coating is not required. Right-hand cut and right-hand spiral flute direction are standard for conventional and climb milling setups.

Key Features

• M7 high speed steel construction provides good wear resistance and toughness for general milling applications
• 4 flutes with right-hand spiral and 30-degree helix angle for efficient chip evacuation
• Bright uncoated finish suitable for general-purpose use on a range of workpiece materials
• Single-end design with 5/32-inch (0.1563-inch) cutting diameter for small-feature machining
• Non-centercutting geometry — intended for peripheral and slotting cuts rather than plunge entry
• Regular-length configuration for standard reach applications without overhang concerns

Compatibility

Designed for use in standard 3/8-inch collets and end mill holders on vertical milling machines and CNC machining centers. Suitable for right-hand spindle rotation setups.

Installation Notes

Installation is performed by a machinist or tool room technician. The tool must be secured in a properly sized and clean collet or end mill holder, torqued to the machine manufacturer's specification using the appropriate wrench. Confirm spindle rotation direction matches the right-hand cut orientation of this end mill before engaging the workpiece. This tool is non-centercutting — do not use for direct plunge operations without a pre-drilled starting hole.
