Hertel 62914023 Roughing End Mill 3/16 in 4 Flute Cobalt

Product Description

The HERTEL 62914023 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 TiAlN coating, it handles tough ferrous and stainless materials while resisting heat buildup at the cutting edge. The fine-pitch, 4-flute spiral geometry with right-hand cutting and right-hand flute direction delivers smooth chip evacuation in slotting and peripheral milling operations. At 3/16 inch in diameter with a 3/8 inch shank and 1/2 inch length of cut, this tool is suited for light profiling and roughing passes in confined features. Machinists and tool-and-die professionals will recognize the value of the TiAlN coating for extended tool life in dry or semi-dry cutting conditions.

This end mill is intended for use in manual mills and CNC machining centers where roughing passes require controlled chip load and heat resistance. The non-centercutting design means it is not suited for plunge milling; it is optimized for ramping entries or side milling. The 2-3/8 inch overall length keeps the tool rigid in short-reach setups, minimizing deflection during heavy passes on hardened or work-hardening materials such as stainless steel and tool steel alloys.

Key Features

• M42 cobalt construction for elevated heat and wear resistance versus standard HSS
• TiAlN coating extends tool life in dry and semi-dry high-temperature cutting
• Fine-pitch, 4-flute spiral geometry for efficient chip evacuation in roughing passes
• Right-hand cut and right-hand flute direction compatible with standard spindle rotation
• Non-centercutting design requires ramp or helical entry — not for direct plunge
• 3/8 inch shank diameter fits standard ER and straight-bore toolholders

Compatibility

Designed as an OEM-style roughing end mill for use in standard milling machines and CNC machining centers accepting a 3/8 inch straight shank toolholder.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Confirm the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Seat the shank fully in the collet or toolholder and torque the retention hardware per the toolholder manufacturer specification. Because this tool is non-centercutting, program ramp or helical entry paths — direct plunge moves will damage the cutting edge.
