Hertel E1051024 Square End Mill 3/8 in 4 Flute Hss

Product Description

The HERTEL E1051024 is a double-end square end mill designed for milling, slotting, and profiling operations on a wide range of workpiece materials. Manufactured from M7 grade high speed steel, this uncoated tool features a 0.375-inch diameter cutting edge with a 0.75-inch length of cut. The spiral flute geometry runs at a 30-degree helix angle with right-hand cut and right-hand flute orientation. With four flutes, it delivers a balance of chip clearance and surface finish quality suited to general-purpose machining work. Machinists and tool-and-die professionals select this style for its versatility in manual mills and CNC machining centers alike.

This end mill is used in general-purpose metal removal applications including face milling, peripheral milling, and slotting in ferrous and non-ferrous materials. The regular-length body and matched shank and cutting diameters make it a straightforward fit for standard collet and end mill holders. It is well suited to job shops, maintenance machining, and production environments where a reliable, non-coated HSS tool is preferred over carbide for interrupted cuts or setups where tool deflection is a concern.

Key Features

• M7 high speed steel construction for toughness in interrupted and general-purpose cuts
• Double-end design provides two usable cutting ends, extending tool life value
• 30-degree helix angle spiral flute for improved chip evacuation
• Right-hand cut and right-hand flute orientation for standard spindle use
• Four flutes for a balance of stock removal rate and finish quality
• Uncoated finish compatible with a wide range of cutting fluids and materials

Compatibility

Designed as an OEM-style replacement or direct-use tool for standard 3/8-inch end mill holders, collet chucks, and Weldon-style holders used in vertical milling machines and CNC machining centers.

Installation Notes

Installation is performed by qualified machinists following standard tool-holding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the holder to the recommended engagement depth per the holder manufacturer guidelines. Verify runout with a dial indicator before beginning a cut, and confirm coolant or cutting fluid compatibility with the workpiece material and tool coating.
