Hertel E599924652 Square End Mill 0.1575 in 4 Flute Carbide

Product Description

The HERTEL E599924652 is a solid carbide square end mill designed for precision milling operations in metal and composite materials. With a 0.1575 inch (4.00 mm) cutting diameter and a 0.5512 inch (14.00 mm) length of cut, this tool delivers tight tolerances in confined pockets, slots, and profiling passes. The four-flute geometry and 30-degree helix angle promote smooth chip evacuation and reduce vibration during both roughing and finishing cuts. Machined from micrograin carbide stock, it maintains edge integrity at elevated cutting speeds. The uncoated finish makes it well-suited for use with cutting fluids in ferrous and non-ferrous applications.

This end mill is used in CNC machining centers and manual mills for slotting, peripheral milling, and pocketing in production and toolroom environments. Its centercutting capability allows direct plunge entry without a pre-drilled pilot hole, which simplifies programming and reduces setup steps. The right-hand cut and standard regular-length configuration make it a straightforward drop-in for most 4.00 mm shank toolholders. It is typically applied by machinists, tool and die makers, and CNC operators working in precision part manufacturing, mold work, and general metalworking.

Key Features

• Solid micrograin carbide construction maintains edge sharpness at high cutting speeds
• Right-hand cut, single-end configuration for standard CNC and manual mill setups
• Uncoated surface compatible with flood coolant and cutting oil applications

Compatibility

Designed for use in 4.00 mm shank toolholders on CNC machining centers and manual vertical mills performing slotting, pocketing, and profile milling operations.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout with a dial indicator before initiating a cutting program to protect both the tool and the workpiece.
