Determination of wear rate is fundamental to life estimation tools heat treated, used in metal forming processes for the metalworking industry. Thus, the main purpose of this article is to determine the five types of wear rate of tool steel produced by powder metallurgy and one by conventional casting, heat-treated by vacuum hardening process, and triple tempered. To this end, we used the test method "pin and drive", which was used for testing three specimens for two different surface finishes (ground and polished) and 10N test load. The results showed that the wear rate will change for different surface finishes studied. It is suggested for further work can be measured the effect of different loads test tool steels, as well as engineering tested coatings on the surface of these materials.
