Abstract
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.
Claims5
A wood-type golf club head comprising:
- a body composed of a titanium alloy material, the body comprising a crown, a sole and a front wall having a perimeter, a body extending 2.0 inches to 5.0 inches rearward from the perimeter of the front wall, wherein the crown, the sole, the front wall, define a hollow interior;
- wherein the wood-type golf club head has a volume ranging from 420 cubic centimeters to 470 cubic centimeters, a moment of inertia, Izz, about the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia, Iyy, about the center of gravity of the golf club head ranging from 2000 grams-centimeters squared to 4000 grams-centimeters squared;
- wherein the wood-type golf club head has coefficient of restitution ranging from 0.81 to 0.94;
- wherein the body is substantially rectangular;
- wherein the body extends rearward from a perimeter of the front wall a distance of least 50% of the length of the body at an angle of 80 degrees to 90 degrees relative to relative to a plane parallel to the farthest extent of the front wall.
