Hertel E1051022 Square End Mill 11/32 in 4 Flute Hss

Product Description

The HERTEL E1051022 is a double-end, four-flute square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Manufactured from M7 high speed steel with a bright/uncoated finish, it offers a cutting diameter of 11/32 inches (0.3438 inches) and a length of cut of 3/4 inches. The 30-degree right-hand helix and right-hand cutting direction support efficient chip evacuation in conventional milling setups. With an overall length of 3-1/2 inches and a 3/8-inch shank diameter, this is a regular-length tool suited for standard mill holders and collet chucks.

This end mill is used in manual mills, CNC knee mills, and machining centers for slotting, profiling, and peripheral milling of ferrous and non-ferrous materials. The double-end design extends tool life by providing two usable cutting ends before replacement. It is appropriate for job shops, tool rooms, and maintenance machining where M7 HSS tooling is preferred over carbide for interrupted cuts or setups where tool breakage risk is elevated. The spiral flute geometry handles a range of conventional roughing and finishing passes at moderate feeds and speeds.

Key Features

• Double-end design provides two cutting ends per tool, extending service life
• M7 high speed steel construction supports toughness in interrupted-cut applications
• Four-flute spiral geometry with 30-degree right-hand helix for efficient chip flow
• Bright/uncoated finish compatible with a wide range of cutting fluids
• Right-hand cutting direction suits standard spindle rotation on most mills
• Not centercutting — not intended for direct plunge operations

Compatibility

Designed as a standard double-end square end mill for use in 3/8-inch collets or end mill holders on manual and CNC milling machines. Verify holder and collet compatibility with the 3/8-inch shank diameter before installation.

Installation Notes

Installation is performed by qualified machinists or tool-room technicians. Power down and lock out the spindle before inserting or changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware per the machine tool manufacturer specifications. Because this tool is not centercutting, avoid direct axial plunge cuts — use ramping or helical entry toolpaths instead.
