Hertel 06822233 Roughing End Mill 5/8 in 4 Flute Cobalt

Product Description

The HERTEL 06822233 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel and finished with a Titanium Nitride (TiN) coating, this tool handles harder workpiece materials while maintaining edge life under heat. The 5/8-inch diameter matches both the shank and length of cut, giving the tool a balanced profile suited for general-purpose roughing passes. Right-hand cutting and right-hand flute direction are standard. Installation and use are handled by machinists and toolroom professionals working with CNC or manual milling equipment.

This end mill is used in production and job-shop environments where fast stock removal is the priority before a finishing pass. The four-flute geometry increases chip load capacity compared to two- or three-flute designs, making it effective in steels, alloy steels, and other ferrous materials where cobalt tooling excels. The regular-length body and 2-3/4-inch overall length keep it rigid in standard tool holders without requiring extended-reach setups.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• Titanium Nitride (TiN) coating extends cutting edge life and reduces friction
• 4-flute design increases feed rate capacity during roughing operations
• Center-cutting capable — can be plunged directly into the workpiece
• Right-hand cut, right-hand helix for standard spindle compatibility
• Regular length body with 5/8-inch shank for rigid tool-holder fit

Compatibility

Designed as an OEM-style roughing end mill for use in standard 5/8-inch collets, milling chucks, or end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully powered down and locked before changing tooling. Seat the shank fully into the holder and torque retention hardware to the tool-holder manufacturer specification. Verify runout with a dial indicator before taking a cut, as excessive runout accelerates wear on cobalt tooling.
