In this paper, drill fred mechanism, cutting depth measuring device and sensing buzzer of drill contact were investigated in order to develop the micro-hole drilling machine. Also, measuring device of cutting resistance was developed in order to estimate cutting resistance from change of cutting condition. The results show that extremely-low fled rate(less then $17{mu}m/S$${mu}{ extrm}{m}$ /s) can be done and cutting depth can be measured by up to 1${mu}{ extrm}{m}$ with developed drilling machine. Accordingly we could assemble a very cheap micro-hole drilling machine($phi$ 0.05~0.5 mm). Also we got the some properties of cutting performance i.e. under the same condition, cutting torque decreases as increase of spindle speed and rapid fled of drill brings about the inferior cutting state under low spindle speed.
