Hertel E2053018 Square End Mill 9/32 Inch Cobalt

Product Description

The HERTEL E2053018 is a cobalt square end mill designed for metal cutting operations in machining environments. Built from M42 cobalt high-speed steel, this double-end tool delivers durability and heat resistance in demanding applications. It features 4 spiral flutes with a 30-degree helix angle, right-hand cut, and right-hand flute orientation. The centercutting geometry allows plunge cutting in addition to peripheral and slot milling. With a 9/32 inch (0.2813 inch) cutting diameter and 11/16 inch (0.6875 inch) length of cut, this end mill is suited for precision material removal in steel, stainless, and other ferrous metals. It ships as an uncoated tool with no chipbreaker.

This end mill is intended for use in manual mills, CNC machining centers, and knee mills where a small-diameter, high-strength tool is required. The 3/8 inch shank diameter accommodates standard collet chucks and end mill holders. The double-end design maximizes tool life by providing two usable cutting ends. It is well suited for job shops, tool rooms, and production environments handling general-purpose ferrous and non-ferrous milling work where cobalt tooling is preferred over carbide for toughness in interrupted cuts.

Key Features

• M42 cobalt construction for improved heat and wear resistance versus standard HSS
• Double-end design provides two cutting ends, extending tool service life
• 4-flute spiral geometry with 30-degree helix for smooth chip evacuation
• Centercutting capability allows plunge milling operations
• Right-hand cut and right-hand flute for standard spindle operation
• Uncoated finish — suitable for use with or without cutting fluid

Compatibility

Designed as an OEM-style replacement or direct-use square end mill for standard 3/8 inch end mill holders and collet chuck setups on manual or CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before inserting the end mill. Tighten set screws or collet nuts to the tool holder specification for the 3/8 inch shank diameter. Always verify runout after installation and confirm spindle direction matches the right-hand cut orientation before engaging the workpiece.
