Hertel 62914445 Roughing End Mill 5/8 in 3 Flute Cobalt

Product Description

The HERTEL 62914445 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a TiCN coating, it delivers heat and wear resistance suited for ferrous metals and harder workpiece materials. The 5/8-inch cutting diameter pairs with a coarse-pitch, 3-flute spiral geometry that channels chips out efficiently and reduces cutting load per flute. The right-hand cut and right-hand flute direction are standard for conventional CNC and manual milling setups. This tool is installed and used by machinists and tool-and-die professionals running production or job-shop milling work.

This end mill is applicable to roughing passes on ferrous and non-ferrous metals where stock removal rate matters more than surface finish. The coarse pitch and 3-flute design reduce chatter and heat buildup compared to fine-pitch multi-flute tools. With a 5/8-inch length of cut and 2-3/4-inch overall length, it fits standard milling chucks and collet holders sized for a 5/8-inch shank. Non-centercutting geometry means it is not suitable for plunge entry — it is a side-milling and peripheral-cut tool.

Key Features

• M42 cobalt HSS construction for elevated heat resistance and extended tool life in hard materials
• TiCN coating reduces friction and increases surface hardness at the cutting edge
• Coarse-pitch, 3-flute spiral geometry promotes chip evacuation and lowers cutting forces
• Right-hand cut and right-hand flute direction compatible with standard milling setups
• Single-end design — 5/8-inch cutting diameter with matching 5/8-inch shank diameter
• Non-centercutting — intended for peripheral and side milling, not plunge cutting

Compatibility

Designed as a standard roughing end mill for use in milling machines, machining centers, and CNC routers accepting a 5/8-inch collet or end-mill holder. Confirm spindle direction and holder runout before use.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the spindle before mounting or removing the tool. Seat the shank fully in the collet or holder and torque the retention nut to the holder specification — do not rely on feel alone. Because this is a non-centercutting tool, program the toolpath for side entry or ramp entry only; vertical plunge moves will damage the cutting edges.
