The direct processing of the high-hardness die materials by a pulse laser is considered to have a great potential in rapid machining with little thermal effect. In this study, a femtosecond laser has been used to fabricate microstructures on cemented tungsten carbide. Development of a hole depth and its shape with irradiated number of pulses in percussion drilling are examined in detail by making its replica. Results for machining a square dent by beam scanning are also presented.
