Hertel 62914031 Roughing End Mill 7/16 in 4 Flute Cobalt

Product Description

The HERTEL 62914031 is a single-end roughing end mill designed for aggressive material removal in ferrous and non-ferrous metalworking applications. Constructed from M42 cobalt high-speed steel and finished with a TiAlN coating, this tool is built to handle elevated cutting temperatures and maintain edge integrity under heavy chip loads. The fine-pitch, 4-flute spiral configuration generates a characteristic chatter-reducing cutting action that distinguishes roughing geometry from standard end mills. The 7/16 inch cutting diameter and 1 inch length of cut make it well suited for roughing passes in pockets, slots, and profile operations where stock removal rate is the priority.

This end mill is used in CNC machining centers and manual milling machines across job shop, toolroom, and production environments. The 3/8 inch shank diameter fits standard ER collet chucks, side-lock holders, and shrink-fit tooling. Right-hand cutting and right-hand flute direction are conventional for the majority of vertical machining center setups. Non-centercutting geometry means this tool requires a pre-drilled entry point or ramping toolpath before engaging full-depth cuts. Machinists working alloy steels, stainless steels, and high-temperature alloys will find the M42 cobalt grade appropriate for the material demands of those applications.

Key Features

• M42 cobalt steel construction provides higher red hardness than standard M2 HSS
• TiAlN coating extends tool life in dry and semi-dry high-speed cutting conditions
• Fine-pitch 4-flute roughing geometry reduces chatter and vibration during heavy passes
• Right-hand cut, right-hand spiral suits standard CNC and manual milling setups
• 3/8 inch shank diameter compatible with common collet and side-lock toolholders
• Single-end configuration — replace rather than re-grind when worn

Compatibility

Designed as a standard-geometry roughing end mill for use in any milling machine or machining center accepting a 3/8 inch straight shank toolholder.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing tooling. Seat the shank to the full recommended grip depth in the toolholder — minimum 1 inch of shank engagement is standard practice to prevent pullout under cutting loads. Because this tool is non-centercutting, do not plunge directly into solid material; use a pre-drilled hole or a programmed ramp entry.
