The greater red hardness of M-42 Cobalt end mills enables these tools to run about 10% faster than conventional HSS end mills. This translates to shorter machining times and permits fuller utilization of available machine horsepower. While Cobalt end mills are initially more expensive than HSS, they retain their sharpness for longer, providing more cuts between grinds and less machine downtime, resulting in lower end mill tooling costs.

Ball-Nose end mills have rounded end cutting edges. This style of end mill is available as a center cutting tool only. It is used where rounded details must be machined in a part (for example, a slot with a rounded bottom). It is also used where sharp machined corners must be avoided. Ball nose end mills are also widely used for delicate cuts on contoured surfaces of molds and dies.
