Hertel 44838605 Roughing End Mill 3/16 in 4 Flute Cobalt

Product Description

The HERTEL 44838605 is a single-end roughing end mill designed for aggressive material removal in metalworking and machining applications. Built from M42 cobalt high-speed steel with a TiCN coating, this end mill delivers elevated heat and wear resistance compared to standard HSS tooling. The 3/16 inch cutting diameter and 4-flute configuration with a fine pitch provide efficient chip evacuation and smooth cutting action on ferrous and non-ferrous materials. With a right-hand cutting and right-hand flute direction, it suits standard CNC and manual milling setups. Installation and use require no center cutting entry — plunge cuts are not supported with this tool.

This end mill is suited for roughing passes in job shop, production, and toolroom environments. It fits applications where a reduced-diameter, short-length-of-cut tool is needed for profiling, slotting, or peripheral roughing in confined areas or on smaller workpieces. The 3/8 inch shank diameter allows compatibility with standard milling chucks, collets, and end mill holders commonly found in both manual and CNC machining centers.

Key Features

• M42 cobalt HSS construction for improved red hardness and tool life over standard HSS
• TiCN coating provides additional surface hardness and lubricity for extended wear resistance
• Fine pitch, 4-flute design optimized for smooth roughing cuts and efficient chip flow
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Single-end configuration with a 3/8 inch shank for secure chuck or collet retention
• Non-centercutting — suited for peripheral and slot milling entries only

Compatibility

Designed as a standard roughing end mill replacement for use with 3/8 inch collets, end mill holders, or milling chucks on CNC machining centers and manual knee mills requiring a 3/16 inch cutting diameter tool.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 3/8 inch shank fully into the holder and torque the retention mechanism per the holder manufacturer's specification. Confirm runout with a dial indicator before beginning a cut, and note that this tool is not centercutting — do not use for direct plunge entry into solid material.
