Hertel E2042132 Square End Mill 1.5 in 6 Flute Cobalt

Product Description

The HERTEL E2042132 is a cobalt square end mill designed for material removal in milling operations on machining centers and manual mills. Built from M42 cobalt high-speed steel, this single-end tool features 6 spiral flutes with a 30-degree helix angle, producing a balance of cutting efficiency and surface finish on ferrous and non-ferrous workpieces. The bright, uncoated finish suits applications where coating is not required or where re-sharpening is anticipated. With a 1.5-inch cutting diameter and 2-inch length of cut, it handles slotting, profiling, and peripheral milling in one setup. Licensed machinists and CNC operators are the primary users of this tool.

This end mill is suited for general-purpose milling in job shop, production, and maintenance machining environments. The 6-flute configuration supports higher feed rates compared to 4-flute tools in finishing and semi-finishing passes. Right-hand cutting and right-hand flute direction make it a standard fit for conventional CNC spindle setups. The regular-length geometry and 1.25-inch shank diameter allow secure clamping in standard end mill holders and collet chucks. It is center-cutting, enabling direct plunge entry into a workpiece.

Key Features

• M42 cobalt high-speed steel construction for elevated heat and wear resistance
• 6 spiral flutes with a 30-degree helix angle for efficient chip evacuation
• Center-cutting geometry allows direct plunge milling
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Bright uncoated finish suitable for re-sharpening and general-purpose use
• Single-end design with a 1.25-inch shank for secure tool holding

Compatibility

Designed as a general-purpose replacement or stock end mill for use in standard end mill holders, collet chucks, and milling machine spindles accepting a 1.25-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The shank must be fully seated and clamped to the tool holder manufacturer minimum engagement depth before operation. Ensure the spindle is fully stopped and locked before inserting or removing the tool. Verify runout after installation with a dial indicator before taking a cut, particularly for finishing applications.
