The use of hard metal tools [4] has increased greatly in recent years.
Today, most turnings, drillings and millings [5] are carried out with this
tool type, characterized by high hardness [6]. Their development is driven
by the evolution of machine tools, which allow and require tools
more and more wear resistant [7–11], more tenacious [12] and which
allow cutting speeds much higher than tools made of HSS. According
to Ceratizit [13], a leader in hard metal manufacturing, 60% of metalworking
tools are steel and the remaining 40% are hard metal tools
[14]. The price of hard metal tools is up to 30% higher than that of
steel tools, but their life is greater. Hard metal tools are able to work
up to 15 million units before requiring sharpening. Normally, the sharpening
can be performed from 8 to 10 times, while the steel tools allow a
maximum of 1 million manufactured pieces.
