Abstract
A golf putter head includes a metal body with a heel, a toe and a front face. The metal body has a central cavity and a pair of lateral cavities in the front face with the lateral cavities being spaced apart and disposed at opposite ends of the central cavity. One of the lateral cavities is located adjacent the heel of the body, and the other lateral cavity is located adjacent the toe of the body. A blind bore formed in each lateral cavity extends into the body in a direction generally perpendicular to the front face. A weight member is disposed in each blind bore. Non-metallic material in the central and lateral cavities forms an insert in the central cavity arranged for impacting a golf ball and other inserts in the lateral cavities for retaining the weight members in the blind bores. Preferably, the non-metallic material in the central cavity and the lateral cavities is polyurethane. The front face of the body, including the inserts, is finished by using a milling machine to provide a flat surface extending between the heel and the toe of the body.
