Abstract: A combination golf club with an insert and golf ball in which the cover of the golf ball and the insert are composed of substantially the same material. The preferred material is a thermoset polyurethane. An alternative material is an ionomer material. The golf club is preferably a putter.

Abstract: The present invention is a golf club head having a club head body with a recess and an insert therein. The insert is composed of a thermoset polyurethane material having a shore D hardness in the range of 42 to 55, and a Bayshore rebound in the range of 51 to 60. The preferred thermoset polyurethane material is formed from a p-phenylene diisocyanate prepolymer and a curing agent. The golf club head is preferably a putter club head, however, it may be a wood club head or an iron club head. The particular thermoset polyurethane provides a soft striking face for feel and a good rebound for distance.

Abstract: A golf club head with a polymer insert is disclosed herein. The polymer insert is disposed in a recess of the club head in which the recess has a depth that is greater than the thickness of the insert. The polymer insert has a plurality of tabs on its perimeter to engage the recess walls to allow the insert to essentially float within the recess. An adhesive is disposed between the rear wall of the recess and an interior surface of the insert. Further, an adhesive is applied between the plurality of tabs, and preferably over the exterior surface of each of the plurality of tabs. The plurality of tabs allow for a uniform surface on the face of the club head TO without having the insert occupy the entire recess. The insert may occupy between 55% to 75% of the face of the club head. Further, the insert may occupy between 10% to 25% of the volume of the club head. Yet further, the insert may be 1% to 5% of the weight of the club head. The insert may be composed of a thermoset material.
