Hertel E7030040 Square End Mill 5/8 Inch 2 Flute Cobalt

Product Description

The HERTEL E7030040 is a cobalt square end mill designed for milling, slotting, and profiling operations on a wide range of ferrous and non-ferrous materials. Built from M42 cobalt high-speed steel and finished with a TiCN coating, this tool delivers improved heat resistance and edge retention compared to standard HSS tooling. It features a 5/8 inch cutting diameter, a 1-5/16 inch length of cut, and a 30-degree spiral helix angle. The centercutting geometry allows for direct plunge entry into the workpiece. This end mill is intended for use by machinists and tooling professionals in production and job-shop environments.

This end mill suits light to medium-duty milling operations in manual or CNC machining centers. The 2-flute configuration provides good chip clearance, making it well suited for slotting and plunge cutting in softer steels, aluminum, and similar materials. The 5/8 inch shank diameter matches the cutting diameter, allowing direct chuck or collet mounting without a step-down adapter. The regular-length body keeps the tool compact and rigid for general-purpose work where extended reach is not required.

Key Features

• M42 cobalt HSS construction for elevated heat resistance and tool life
• TiCN finish reduces friction and improves wear resistance at the cutting edge
• 30-degree helix angle promotes smooth chip evacuation during cut
• Centercutting design allows direct plunge milling without pre-drilling
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• 2-flute geometry provides maximum chip clearance for slotting operations

Compatibility

Designed as a general-purpose replacement or working end mill for CNC machining centers and manual mills accepting a 5/8 inch straight shank via collet, end mill holder, or set-screw holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the spindle is fully powered down and locked out before inserting or removing any tooling. Seat the shank to the full recommended insertion depth in the holder to prevent pullout under cutting loads. Verify runout with a dial indicator before committing to a production cut.
