Hertel E199921324 Square End Mill 13/32 in 4 Flute Hss

Product Description

The HERTEL E199921324 is a double-end, four-flute square end mill designed for general-purpose milling operations in a wide range of ferrous and non-ferrous materials. Built from high speed steel with a bright uncoated finish, this tool has a 13/32 inch (0.4063 inch) cutting diameter and a 1 inch length of cut. The 1/2 inch shank diameter fits standard milling chucks and collet holders, and the 4-1/2 inch overall length provides reach for typical vertical and horizontal milling setups. The 30-degree helix angle promotes smooth chip evacuation, while the center-cutting geometry allows the tool to plunge directly into the workpiece without pre-drilling.

This end mill suits job shop, toolroom, and maintenance machining environments where operators are profiling, slotting, or side-milling on manual mills or CNC machining centers. The double-end configuration extends tool life by offering a second usable cutting end before the tool is retired. Right-hand cut and right-hand spiral flute direction are standard for conventional milling machine spindles. The uncoated HSS construction makes it straightforward to resharpen in-house with standard grinding equipment.

Key Features

• Double-end design provides two cutting ends per tool, extending usable life
• Center-cutting geometry allows direct plunge entry without a pilot hole
• 30-degree helix angle promotes efficient chip evacuation during slotting and profiling
• High speed steel construction supports in-house resharpening
• Bright uncoated finish suitable for use with standard cutting fluids on a broad range of materials
• Right-hand cut and right-hand flute direction compatible with standard milling spindles

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool compatible with any milling machine or machining center equipped with a 1/2 inch collet, end mill holder, or milling chuck accepting standard shank tooling.

Installation Notes

This tool should be installed and changed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Verify that the shank is fully seated and the collet or set screw is properly torqued according to the holder manufacturer specifications. Always confirm cutting direction and spindle rotation match the right-hand flute orientation before starting the cut.
