Friction will be less at higher speeds.

Yes you are right @Naman as the speed decreases, the friction between the tool and W/P increases. So as the friction increases wear also increases.

Naman Gandhi said:   1 decade ago
In slow speed the contact between surfaces are more so it is obvious that at slow speed it will wear more.

Cemented carbide tools are used for machining stainless steels, carbon steels which are very hard.

Because it is powder metallurgy technique and cobalt binder and its temperature is high.

Kareem said:   1 decade ago
Because the time available for wearing is more.
