M42 exhibits excellent wear resistance by virtue of high heat-treated hardness (68 to 70 HRC), and the high cobalt content imparts the hot hardness.

As such, the cutting edges on tools made from M42 super high speed steel stay sharp and hard in heavy-duty and high-production cutting applications.

M42 is also “less prone” to chipping when used for interrupted cuts and costs less when compared to the same tool made of carbide. Reminder, that the cutting edge chipping is never acceptable and all efforts should be made to minimize or eliminate.

To increase the life of high-speed steel, tools are sometimes coated; one such coating is TiN — Titanium Nitride. Most coatings generally increase a tool's hardness and or lubricity. While adding a layer of protection from heat do to friction between the material being drilled and the cutting edge. A coating allows the cutting edge of a tool to cleanly pass through the material also assist to decrease the temperature associated with the cutting process and increase the life of the tool.
