Hertel 02477347 Roughing End Mill 5/8 Inch 4 Flute Cobalt

Product Description

The HERTEL 02477347 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and coated with Titanium Nitride (TiN), it delivers extended tool life and heat resistance in demanding cutting environments. The 5/8 inch diameter, 4-flute configuration with a right-hand cutting and right-hand flute direction makes it well suited for roughing passes on ferrous and non-ferrous metals. Overall length is 3.75 inches with a 1.625 inch length of cut. This is a non-center-cutting tool and should not be used for plunge cuts.

This roughing end mill is used in vertical machining centers, knee mills, and manual or CNC milling setups where high stock removal rates are the priority. The TiN coating reduces friction and extends cutting edge life, particularly useful in production environments where tool changes need to be minimized. The 5/8 inch shank diameter matches the mill diameter for straightforward toolholder setup. Typical applications include roughing slots, pockets, and peripheral cuts in steel, alloy steel, and similar materials.

Key Features

• M42 cobalt HSS construction for heat and wear resistance in tough materials
• Titanium Nitride (TiN) coating reduces friction and extends tool life
• 4-flute, single-end design optimized for roughing and high material removal
• Right-hand cut and right-hand flute direction for standard milling setups
• Regular length geometry with 1.625 inch length of cut and 3.75 inch overall length
• Non-center-cutting — not suitable for plunge entry

Compatibility

Designed for use in standard 5/8 inch end mill toolholders including collet chucks, set-screw holders, and hydraulic holders compatible with 5/8 inch shank diameters.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended engagement depth in the toolholder and verify runout before cutting. Because this is a non-center-cutting end mill, always enter the cut from the side or use a pre-drilled hole — never plunge directly into solid material.
