Hertel 06822019 Roughing End Mill 5/8 in 4 Flute Cobalt

Product Description

The HERTEL 06822019 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a Titanium Nitride (TiN) coating, it delivers strong wear resistance and heat tolerance in demanding cutting environments. The 5/8-inch diameter, 4-flute design with right-hand cutting and flute direction produces fast stock removal while maintaining reasonable surface quality. With a 1.625-inch length of cut and 3.75-inch overall length, this is a standard-reach tool suited to general roughing passes on a variety of workpiece materials. Installation is performed by machinists and tooling professionals in CNC and manual milling setups.

This roughing end mill is suited for production and job-shop milling applications where rapid material removal is the priority. The TiN coating extends tool life compared to uncoated cobalt tooling, making it appropriate for higher-volume roughing on steels, stainless, and similar alloys. The non-centercutting, single-end configuration means it is intended for side milling, slotting, and peripheral cuts rather than plunge entry. Regular length geometry fits standard tool holders and collet chucks without extended-reach considerations.

Key Features

• M42 cobalt HSS construction for improved red hardness and wear resistance over standard M2 tooling
• Titanium Nitride (TiN) coating reduces friction and extends tool life in continuous cutting
• 4-flute roughing geometry accelerates stock removal on roughing passes
• Right-hand cut and right-hand flute direction for standard spindle operation
• Non-centercutting design optimized for peripheral and side milling, not plunge cutting
• Regular length profile compatible with standard milling collets and end mill holders

Compatibility

Designed as a standard-shank roughing end mill with a 5/8-inch shank diameter, compatible with 5/8-inch collets, end mill holders, and milling chucks used in CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Secure the shank fully within the holder to the minimum insertion depth recommended by the holder manufacturer to prevent pullout under cutting loads. Do not use this tool for plunge entry due to its non-centercutting geometry.
