1. Desempenho de Ferramentas Reafiadas - Furação
The present work evaluated the performance of step drills, new and after regrinding. The way of regrinding the drills after they reached the end of tool life criterion was also varied. The following variables were also considered: type of coatings (uncoated, TiAlN e AlCrN) and the routine of re-coating them after regrinding (no recoating, recoating over the

2. Um estudo comparativo do comportamento das afiações conica e conica radial (racon) em brocas helicoidais de aço rapido / A comparative study of conical and radiused conventional point (racon) behaving in high speed stell twist drill
The main goal of this work is to study the behaving of Racon (radiused conventional point) and Conical (conventional) drill points in high speed stell twist drills and analyse their performance, trying to correlate them to their geometrical features. For this purpose, tests with two different machinability materiais, the SAE 4340 and SAE 1045 steeIs, were ca
