Hertel 62888813 Roughing End Mill 1/2 in 4 Flute Cobalt

Product Description

The HERTEL 62888813 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a TiAlN coating, it handles interrupted cuts, tough alloys, and high-heat applications where standard HSS tools would wear prematurely. The 1/2 inch diameter, 4-flute configuration with a coarse pitch geometry breaks chips efficiently and reduces chatter during heavy roughing passes. With a 1.625 inch length of cut and a 3.625 inch overall length, it fits standard milling setups without extended-reach considerations. This tool is installed by machinists, tool-and-die professionals, and CNC operators working in job shops and production environments.

This roughing end mill suits ferrous and non-ferrous stock removal on vertical mills, knee mills, and CNC machining centers. The right-hand cutting direction and right-hand spiral flutes are standard for conventional milling machine spindles. The centercutting design allows plunge entry, giving the operator flexibility in toolpath programming. The 1/2 inch shank diameter fits ER collet chucks, end mill holders, and set-screw holders common in both manual and CNC setups.

Key Features

• M42 cobalt construction for elevated heat and wear resistance over standard M2 HSS
• TiAlN coating extends tool life in dry and semi-dry cutting conditions
• Coarse pitch roughing geometry breaks chips and reduces cutting forces
• Centercutting capable — supports direct plunge entry without pre-drilling
• Right-hand cut, right-hand spiral — compatible with standard spindle rotation
• Single-end design with 1/2 inch shank for broad holder compatibility

Compatibility

Designed as a standard 1/2 inch shank roughing end mill suitable for use in ER collet chucks, end mill holders, and set-screw style tool holders on vertical mills and CNC machining centers with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle powered down and the machine in a safe, locked-out state. Ensure the shank is fully seated in the holder to the recommended minimum engagement depth before tightening. Verify runout with a dial indicator before the first cut. Do not exceed the tool manufacturer's recommended depth of cut or feed rate for the workpiece material.
