In this research, varying hole shape and surface are investigated under following conditions^ various cutting speed, feeding speed, and types of drill. Experiments were performed in four different cutting speeds:20,60,100,and 140[m/min].A non-diamond coated carbide drill and a diamond coated carbide drill were used in experiment for the comparison. In the result, the relatively best shaped hole with less burrs was drilled at the feeding speed 20[m/min].The hole drilled by diamond coated drill was better than that of non-diamond coated drill: less burrs and better shape of the hole. Moreover, diamond coated drill had less wear during drilling process than non-diamond coated drill. Also, strongly warped angle diamond coated drill drills the hole with better shape and less burrs than that of weakly warped angle diamond coated drill; however, the blade of strongly warped angle drill is easy to be chipped since the blade is sharp.
