Vokey Design Spin Milled(tm) wedges are unique new products that provide a truly discernible performance option - increased spin. By working with Tour players to create wedges that performed under the most challenging major championship conditions, Bob has developed a precisely machined, tight tolerance groove that provides the player with increased spin on both full and partial wedge shots. Vokey Spin Milled wedges feature a CNC machined cut face and grooves. A special circular saw style cutting tool is used to create precise grooves with a steeper draft angle and a tighter edge radius for increased friction. Vokey Spin Milled wedges have 30% more groove volume than a conventional wedge. This provides more consistent and higher spin, particularly from grassy lies and wet conditions. Spin Milled gives you the confidence to successfully execute more challenging short game shots.
