Hertel E1051023 Square End Mill 23/64 in 4 Flute Hss

Product Description

The HERTEL E1051023 is a double-end, 4-flute square end mill manufactured from M7 high speed steel. It carries a 23/64 inch (0.3594 inch decimal) cutting diameter with a 3/4 inch length of cut and a 3/8 inch shank diameter. Overall length is 3.5 inches. The spiral flute geometry runs at a 30-degree helix angle with right-hand cut and right-hand flute direction. The tool is uncoated and supplied in a regular length configuration. Machinists and tool-and-die professionals use this end mill for general-purpose milling operations where M7 HSS offers adequate hardness and toughness without the cost of carbide.

This end mill suits light-to-medium milling work in ferrous and non-ferrous metals, plastics, and similar machinable materials on manual mills and CNC machining centers. The double-end design extends usable tool life by providing a second cutting end when the first end wears. The 30-degree helix promotes smooth chip evacuation and reduced cutting forces. It is a standard fitment for job shops, maintenance machining, and toolroom operations requiring a fractional-diameter square profile cutter in the 23/64 inch range.

Key Features

Compatibility

Designed as a standard replacement or stocking end mill for 3/8 inch shank collets and toolholders used in conventional and CNC milling machines accepting fractional HSS end mills in the regular length class.

Installation Notes

Installation is performed by a machinist or toolroom professional. Secure the 3/8 inch shank in a properly sized collet or end mill holder and verify runout before operation. Ensure the spindle and machine are fully powered down and locked out before changing tooling. Do not exceed the material and speed-feed parameters appropriate for M7 HSS at this diameter.
