摘要: A face or face insert (40) for a golf club head (20) is disclosed herein. The face (40) has an interior surface (40a) with a first thickness section (200) and a second thickness region (205). The first thickness section (200) preferably has a thickness that is at least 0.025 inch greater than the thickness of the second thickness region (205). In a most preferred embodiment, the first thickness section (205) has a X shape. The face or face insert (40) with variable thickness allows for a face or face insert (40) with less mass in a golf club head (20) that conforms to the United States Golf Association regulations.

摘要: A golf club head (42) having a delta of the coefficient of restitution between a geometric face center of the face (72) and a location (806) 0.5 inch sole-ward from the face center that is less than 0.065. The golf club head (42) preferably has a volume ranging from 420 cubic centimeters to 470 cubic centimeters. The golf club head (42) preferably has a moment of inertia about the Izz axis through the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared.

摘要: A golf club head (42) having a substantially square or rectangular body is disclosed herein. The golf club head (42) preferably has a volume ranging from 420 cubic centimeters to 470 cubic centimeters. The golf club head (42) preferably has a moment of inertia about the Izz axis through the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared.
