Hertel E2037132 Square End Mill 1.5in 6-flute Cobalt

Product Description

The HERTEL E2037132 is a 6-flute cobalt square end mill engineered for heavy-duty milling in ferrous and hard materials. Built from M42 cobalt high-speed steel, it delivers superior heat and wear resistance compared to standard HSS tooling. The 1.5-inch cutting diameter and 8-inch length of cut make this an extra-long reach tool suited for deep-pocket milling, slotting, and profiling operations where standard-length end mills cannot reach. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This tool ships uncoated and is intended for use by machinists and toolroom professionals working on CNC and manual milling machines.

This end mill is designed for applications requiring extended reach into deep cavities or tall workpieces. The extra-long overall length of 10.5 inches and 8-inch length of cut support deep-pocket work in mold and die, aerospace structural components, and heavy industrial part machining. The right-hand cut, right-hand spiral flute configuration is the standard setup for conventional and climb milling on most vertical machining centers. It is not center-cutting, so it is not suited for direct plunge operations without a pre-drilled pilot hole.

Key Features

• M42 cobalt high-speed steel construction for elevated heat resistance and extended tool life in tough materials
• 6-flute geometry increases chip load per tooth and improves surface finish in finishing passes
• 30-degree helix angle promotes smooth cutting action and efficient chip flow out of deep pockets
• Extra-long 8-inch length of cut with 10.5-inch overall length for deep-reach milling applications
• Right-hand cut and right-hand spiral flute for standard CNC and manual milling machine spindle compatibility
• Uncoated finish — ready for use with cutting fluids in ferrous and cobalt-appropriate machining environments

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for milling machines accepting a 1.25-inch shank diameter end mill holder or collet chuck.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify that the end mill holder or collet is rated for the 1.25-inch shank diameter and that the holder is clean and free of chips or burrs before seating the tool. Because this tool is not center-cutting, avoid direct plunge cuts into solid material without a pre-drilled entry point.
