TaylorMade M2 Irons Steel ShaftsNot since the Burner Iron of 2009 have we seen an iron where the ball explodes of the clubface and shows distance gains that the testing of the M2 Iron has shown.Many manufacturers have increased distance purely by making the iron lofts stronger or increasing the length of the shafts. Although this increases the distance, often it has made the ball flight too low so shots that landed on the greens wouldnt hold. TaylorMade have addressed this by engineering irons that fly far and high, resulting in M2 irons can deliver dramatic distance from every iron, for all golfers. This synergy of distance and height was accomplished through a unique combination of features and technologies.FeaturesThick-Thin Fluted Hosel - 3 grams of extra mass trapped in the hosel was removed. That weight was then distributed as low as possible throughout the head to lower the CG and promote higher launch and more ball speed.360° Undercut - This expands the unsupported face area for more ball speed across the face. It also removes weight from the topline to create ultra-low CG. This allows for stronger lofts that maximize distance without sacrificing the high peak trajectory that results in long, playable shots from each iron.Speed Pocket - Increased flexibility due to an even thinner sole increases launch angle and preserves ball speed, improving forgiveness for shots struck below the center of the face.Thin Face with Inverted Cone Technology - Works in conjunction with the Speed Pocket to enable fast, consistent ball speeds across the face that push the limits of distance performance in an iron.3D Sound & Feel System - A light but extremely stiff 3D-badge system that manages sound and eliminates unwanted vibrations for superior feel, giving golfers a pure feeling distance iron.
