B-6 Heater 7 Iron RH Stainless Steel Shaft Description The Heater B6 Irons (TaylorMade M6 clones) have a 360º deep undercut cavity. The sunk channel at sole promotes stability at impact and forgiveness on off-center shots. The undercut cavity expands the unsupported face area for more ball speed across the entire face. It also removes weight from the topline to create an ultra-low center of gravity. The steel bar feature over the cavity supports the top line and reduces vibration. The overall lower center of gravity placement promotes a high launch and penetrating ball flight. Condition Pre owned in very good condition. Item shows normal wear.
