Hertel 44838985 Roughing End Mill 1/2 in 4 Flute Cobalt

Product Description

The HERTEL 44838985 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and coated with TiCN, it delivers improved heat resistance and wear life compared to standard HSS tooling. The coarse pitch flute geometry breaks chips efficiently and reduces cutting forces during heavy roughing passes. With a 0.5 inch mill diameter, four flutes, and a 0.625 inch length of cut, this tool suits production environments where stock removal rate matters. Licensed machinists and toolroom operators are the primary users.

This end mill fits standard milling applications where a 0.5 inch shank diameter is required. The right-hand cut and right-hand flute direction make it compatible with conventional vertical and horizontal milling machines as well as CNC machining centers running standard spindle rotation. It is suited for roughing passes on ferrous and non-ferrous metals in job shop, tool and die, and general metalworking environments. The TiCN coating extends tool life in abrasive or harder workpiece materials.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance
• TiCN coating improves hardness and reduces friction at the cutting edge
• Coarse pitch design promotes chip evacuation during heavy roughing cuts
• Right-hand cut and right-hand helix for use on standard spindle configurations
• Single-end design with 0.625 inch length of cut and 2.625 inch overall length
• 0.5 inch shank diameter matches standard collet and end mill holder sizes

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard 0.5 inch collet chucks, side-lock holders, and shrink-fit holders used on vertical mills and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify holder runout with a dial indicator before committing to a roughing pass. Do not use this end mill for plunge cutting, as it is a non-center-cutting design.
