Hertel E1039064 Square End Mill 1 in 4 Flute Hss

Product Description

The HERTEL E1039064 is a single-end, square-profile end mill designed for general-purpose milling operations in ferrous and non-ferrous metals. Manufactured from M7 high speed steel in an uncoated finish, it features 4 spiral flutes with a 30-degree helix angle and a right-hand cut with right-hand flute direction. The 1-inch cutting diameter pairs with a 2-inch length of cut, giving machinists ample reach for slotting, profiling, and peripheral milling. Its centercutting geometry allows direct plunge entry without a pre-drilled hole. This tool is installed and operated by machinists and CNC programmers in job shop, maintenance, and production environments.

This end mill is suited for milling operations on manual knee mills, CNC vertical machining centers, and bridgeport-style machines. The regular-length body and 1-inch straight shank fit standard R8, CAT, BT, and other common toolholding systems that accept a 1-inch shank. Typical applications include shoulder milling, full-slot cutting, and step milling in steel, cast iron, aluminum, and similar workpiece materials. The 4-1/2-inch overall length keeps the tool rigid in setups where minimal overhang is possible.

Key Features

• M7 high speed steel construction for durability in ferrous and general-purpose milling
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design enables direct plunge milling without pre-drilling
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Uncoated finish suitable for use with cutting fluids across a wide range of materials
• Regular length body promotes rigidity and minimizes deflection

Compatibility

Designed as an OEM-style replacement or direct substitute for standard 1-inch shank square end mills used in conventional and CNC vertical milling applications.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with proper toolholding torque and runout requirements. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the toolholder. Use a calibrated torque wrench and the toolholder manufacturer's specifications when tightening collets or set screws. Inspect the cutting edges for chips or wear before each use and replace the tool if edge condition is compromised.
