Spin Milled Grooves
A proprietary Spin Milling process allows SM8 grooves to be meticulously engineered maximizing spin and durability. The first step in this process is cutting the face with a high speed saw making it perfectly flat. Once this is done, each and every groove is individually cut based on the loft and finish. Low lofted wedges have narrow, deep grooves while high lofted wedges have wide, shallow grooves. The next step involves cutting micro-grooves in between the grooves to maximize spin on partial shots. To make the most durable groove in golf, the impact area is given a proprietary heat treatment . The process is finalized with a 100% inspection for conformity to the rules of golf on each groove on every wedge head.
