Hertel E1034048 Square End Mill 3/4 Inch 4 Flute Hss

Product Description

The HERTEL E1034048 is a single-end, square-profile end mill designed for milling operations in ferrous and non-ferrous materials. Built from M7 high speed steel, this uncoated tool features a 30-degree right-hand spiral flute geometry that promotes efficient chip evacuation and stable cutting performance. With a 3/4 inch cutting diameter and a 3 inch length of cut, this is a long-series end mill suited for deeper reach applications where a standard-length tool cannot access the required depth. It is used by machinists and toolroom professionals in manual mills, CNC machining centers, and knee mills.

This end mill is appropriate for general-purpose milling tasks including slotting, profiling, and peripheral milling in steel, aluminum, and similar materials. The long length of cut makes it well suited for side-milling deep features, pocketing with extended reach, and applications where the workpiece geometry requires additional clearance between the shank and the cut zone. It is not a centercutting tool, so plunge milling is not recommended. Typical users include job shop machinists, toolroom technicians, and production machinists working on manual or CNC vertical milling equipment.

Key Features

• M7 high speed steel construction for wear resistance in general-purpose milling
• 30-degree right-hand spiral flute geometry for efficient chip flow
• Long-series design with 3 inch length of cut for extended reach applications
• 4-flute configuration balances feed rate capability with chip clearance
• Uncoated finish suitable for use with standard cutting fluids
• Non-centercutting design — not intended for plunge or drilling operations

Compatibility

Designed as a standard 3/4 inch shank end mill compatible with R8, CAT, BT, and other common milling machine spindle toolholders that accept a 3/4 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist familiar with milling tool setup and machine operation. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank with appropriate minimum engagement in the toolholder per the toolholder manufacturer guidelines. Verify runout with a dial indicator before cutting, as excessive runout will reduce tool life and surface finish quality.
