Hertel E2051032 Square End Mill 0.5in 4 Flute Cobalt

Product Description

The HERTEL E2051032 is a cobalt square end mill designed for milling operations in ferrous and difficult-to-machine materials. Built from M42 cobalt high-speed steel, this double-end tool delivers consistent cutting performance across both ends, extending tool life and reducing changeover frequency. The 0.5 inch diameter with a 1 inch length of cut and 30-degree spiral helix angle provides efficient chip evacuation and a smooth finish. With 4 flutes and a right-hand cut and right-hand flute configuration, it handles a wide range of slotting, profiling, and peripheral milling applications in standard machining environments.

This end mill is suited for use in manual mills, CNC machining centers, and knee mills in job shop, maintenance, and production settings. The regular length classification and 4-1/8 inch overall length make it a practical general-purpose choice for machinists working with steel, stainless, and other alloys where cobalt tooling is preferred over carbide for toughness and resistance to chipping. The uncoated finish is appropriate for applications where lubrication is applied during cutting.

Key Features

• M42 cobalt construction for toughness in ferrous and hard materials
• Double-end design provides two usable cutting ends per tool
• 30-degree helix angle promotes efficient chip evacuation
• 4-flute spiral configuration for smooth surface finish
• Right-hand cut and right-hand flute orientation
• Non-centercutting geometry — not suitable for plunge cuts

Compatibility

Designed as a general-purpose OEM-style replacement or direct-use cobalt square end mill compatible with any 1/2 inch collet or end mill holder in standard milling setups.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully in a 1/2 inch collet or end mill holder and torque to the tool holder manufacturer specifications. Confirm spindle direction matches the right-hand cut orientation before engaging the workpiece. Because this is a non-centercutting tool, do not use for direct plunge operations.
