Hertel 02499200 Roughing End Mill 1/2 in 4 Flute Cobalt

Product Description

The HERTEL 02499200 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting ferrous metals, stainless steels, and other tough alloys. The 1/2 inch diameter cutter features 4 flutes with a right-hand cutting and right-hand flute direction, a 1.25 inch length of cut, and a 3.25 inch overall length. The bright, uncoated finish is suited for applications where coating adhesion is not required or where re-sharpening is anticipated. This tool is used by machinists and tool-and-die professionals in manual and CNC milling setups.

The 02499200 is intended for roughing passes where stock removal rate is the priority over surface finish. The center-cutting design allows plunge entry, adding flexibility in pocket milling and slotting operations. The regular length profile fits standard milling chucks and collet holders without requiring extended-reach setups. It is well suited to job shops, maintenance machining, and production environments where cobalt tooling is preferred over carbide due to shock resistance or cost considerations.

Key Features

• M42 cobalt high-speed steel construction for heat and wear resistance
• 4-flute configuration optimized for roughing and rapid stock removal
• Center-cutting capable — supports plunge milling and pocket entry
• Right-hand cut, right-hand helix geometry for conventional milling setups
• Bright uncoated finish — resharpenable without coating concerns
• Regular length profile for compatibility with standard toolholders

Compatibility

Designed as an OEM-style replacement or standard tooling option for 1/2 inch collet holders, end mill adapters, and milling chucks used in vertical and horizontal milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended engagement depth in the toolholder to prevent pullout under roughing loads. Verify runout with an indicator before beginning cuts when tight tolerances are required.
