Hertel 06821896 Roughing End Mill 2 in 6 Flute Cobalt

Product Description

The HERTEL 06821896 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it carries 6 right-hand flutes with a coarse pitch geometry that breaks chips efficiently and reduces cutting forces during heavy passes. The 2-inch cutting diameter and 4-inch length of cut make it suited to deep-pocket and side-milling work on ferrous and non-ferrous metals. This tool is installed and operated by machinists and tool-and-die professionals using standard milling machines or CNC machining centers.

This roughing end mill is used in production and job-shop environments where high stock removal rates are the priority. The coarse-pitch flute design creates a shearing action that minimizes chatter and heat buildup, which extends tool life in interrupted cuts and difficult alloys. The 2-inch shank diameter matches the cutting diameter, providing a rigid, chatter-resistant setup in standard milling chucks or collet holders. The right-hand cutting direction is compatible with conventional and climb milling operations on vertical and horizontal mills.

Key Features

• M42 cobalt construction for enhanced heat and wear resistance compared to standard M2 HSS
• 6-flute coarse-pitch design for efficient chip breaking and high material removal rates
• 2-inch cutting diameter with 4-inch length of cut for deep-pocket milling capability
• Center-cutting geometry allows plunge entry without a pre-drilled pilot hole
• Bright, uncoated finish suitable for use with or without cutting fluid
• Right-hand flute and cutting direction for use on conventional milling setups

Compatibility

Designed as a direct-fit roughing end mill for standard 2-inch milling chucks, collet holders, and end mill adapters used on vertical mills, horizontal mills, and CNC machining centers.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Secure the shank in a properly sized end mill holder or collet to the full recommended engagement depth and verify runout before cutting. Cutting speeds and feed rates should follow published data for M42 cobalt tooling against the specific workpiece material. Operators should wear appropriate eye and face protection during all milling operations per OSHA and shop safety requirements.
