Abstract

A golf driver club head with air holes, for increasing the speed of the driver and the accuracy of the flying direction of the ball, is provided. The front face of the driver club head is flat. Two shallow vertical arc shape holes are developed on the left side and another two shallow vertical arc shape holes are developed on the right side of the front face of the club head. One circular hole is developed at the center of the rear face of the club head. Air comes through the four vertical arc shape holes and passes through the empty inner space of the club head and goes out through the circular hole.
