Hertel E1051010 Square End Mill 5/32 in 4 Flute Hss

Product Description

The HERTEL E1051010 is a double-end, square-profile end mill designed for milling, slotting, and profiling operations on ferrous and non-ferrous materials. Manufactured from M7 high speed steel in an uncoated finish, it features a 5/32 inch (0.1563 inch) cutting diameter and a 30-degree spiral helix with four right-hand flutes. The 3/8 inch shank diameter accommodates standard collets and end mill holders. With a regular-length classification and a 7/16 inch (0.4375 inch) length of cut, this tool is suited to light-to-medium material removal where HSS tooling is appropriate. Licensed machinists and toolroom operators are the primary users.

This end mill is intended for general-purpose machining applications in job shops, maintenance facilities, and production environments. It is well suited to milling operations requiring a compact cutting diameter, such as narrow slot cutting, profile work, and step milling in steel, aluminum, brass, and similar materials. The double-end design extends service life by providing two usable cutting ends before the tool is retired. The non-centercutting geometry limits use to peripheral and side milling — plunge milling is not recommended with this configuration.

Key Features

• M7 high speed steel construction for wear resistance in general-purpose milling
• Double-end design provides two cutting ends, maximizing tool utilization
• 30-degree helix angle with spiral fluting for smooth chip evacuation
• Right-hand cut, right-hand flute orientation for standard spindle use
• Uncoated finish — compatible with cutting fluid applications without coating compatibility concerns
• Non-centercutting geometry — suited for peripheral, slot, and side milling

Compatibility

Designed as an OEM-style tooling option for use in standard end mill holders and collet chucks accepting a 3/8 inch shank diameter, across vertical machining centers, knee mills, and manual milling machines.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the machine locked out per applicable shop safety procedures. Ensure the collet or end mill holder is clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping to confirm proper tool alignment. This tool is non-centercutting — do not use for direct plunge operations.
