Hertel E2040132 Square End Mill 1-1/2 in Cobalt 4 Flute

Product Description

The HERTEL E2040132 is a cobalt square end mill designed for material removal in milling operations across a range of ferrous and hard metals. With a 1.5-inch cutting diameter and a 4-inch length of cut, it handles deep slotting and profiling in applications where reach beyond standard-length tooling is required. Constructed from M42 cobalt high-speed steel, the tool delivers heat resistance and edge retention under demanding cutting conditions. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation, and the centercutting design allows for direct plunge entry into the workpiece. Machining shops and toolroom technicians are the primary installers and users of this tool.

This end mill is suited for milling operations on steel, stainless steel, cast iron, and similar hard materials in both production and toolroom environments. Its long-series geometry makes it appropriate for deep-pocket milling, stepped features, and contoured profiles where a standard-length end mill would not reach. The 1.25-inch shank diameter accommodates standard ER and side-lock collet systems or end mill holders of matching bore size. The uncoated finish makes it a practical choice for shops that prefer to apply cutting fluids directly to the tool surface.

Key Features

• 1.5-inch cutting diameter with 4-inch length of cut for extended reach milling
• M42 cobalt high-speed steel construction for heat and wear resistance
• 4-flute, 30-degree right-hand spiral geometry for efficient chip evacuation
• Centercutting design allows direct plunge cutting into workpiece
• Right-hand cut and right-hand flute configuration for standard CNC and manual milling spindles
• Uncoated finish compatible with flood coolant and cutting oil applications

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for milling machines accepting a 1.25-inch shank diameter in standard end mill holders, collet chucks, or side-lock holders.

Installation Notes

This tool is installed by machinists and toolroom technicians on CNC or manual milling machines. Always confirm spindle is fully stopped and machine is in a safe, locked-out state before changing tooling. Seat the shank fully in the holder and torque set screws or collet nuts per the toolholder manufacturer specification. Inspect cutting edges for chips or wear before each use and replace tooling when edge condition degrades to avoid workpiece damage or tool failure.
