Abstract
A putter golf club head includes a body fitted with relatively high-density heel and toe inserts. A golf putter club head includes a body formed of a first material (e.g., titanium) having a density of approximately 3.0 g/cm3 to 7.0 g/cm3. Two cavities are formed in the body, one adjacent to the heel region of the body, and another adjacent to the toe region. Inserts are provided in each of the two cavities and are formed of a second material (e.g., tungsten) having a density ranging from approximately 15.0 g/cm3 to 20.0 g/cm3. The cavities may be configured such that they extend to (or are bounded by) the bottom surface and/or the front face of the body. In one embodiment, the body of the putter club head has an elastic modulus greater than approximately 90 GPa while the density of the insert material is greater than the density of the body material by a factor of at least 3.0.
