M42 Cobalt Roughing End Mills

Cobalt Roughing End Mills are designed for roughing or hogging large amounts of metal prior to a finish milling operation. They are used for deep slotting or heavy side cuts and require less power than conventional end mills. Ideal for machining high alloyed steels, titanium alloys, and cast alloys. M42 Cobalt offers increased wear and heat resistance, higher speeds and feeds and long life in production applications.

In this category You will find coarse, medium, fine and truncated tooth pitch.

Coarse pitch = heavier feed rates

Medium Pitch = less than heavier feed rates, Aids in reducing chatter and vibration

Fine Pitch = For use on Inconel, Hastalloy, Titanium alloys and other High Tensile strength, abrasive and harder materials up to 40 Rockwell - This style reduces cutting pressure over more teeth which aids in extending end mill life

Truncated = This geometry reduces chatter - dramatically - For maximum performance reduce feed rate by 10%
