The Mizuno MX SpeedMetal delivers an evolved iron design that blends explosive distance with enhanced forgiveness — all wrapped in a sharp, confidence-inspiring head shape that looks great at address. Incorporating Mizuno's latest Seamless Cup Face and NEW CORTech Face technologies, the MX SpeedMetal enlarges the high-velocity impact zone for greater ball speed and more consistent performance across the entire face. The design philosophy is clear: make it easier to hit further, without sacrificing feel, control, or visual appeal. This set is offered with shafts extended by +0.5" for taller players or those who prefer a longer club length.
Shafts extended by +0.5" (approx. +1.27 cm) over standard length.
The Seamless Cup Face eliminates the weld seam between the face and the sole, creating an uninterrupted, precision-formed construction that allows more uniform flex at the moment of impact. Thinned areas revolve 360° around the entire perimeter of the head, expanding the rebound area for maximum ball speed across the whole face — not just the sweet spot. This seamless design significantly improves energy transfer efficiency, generating faster ball speeds and a more penetrating, piercing ball flight. The deep centre of gravity that results from wrapping the face around the head's perimeter also promotes a higher launch angle, adding carry distance and a more controllable descent angle into greens.
The re-engineered CORTech geometry expands the reinforced section of the 17-4 stainless steel face both vertically and horizontally, creating a wider high-rebound zone that returns more energy to the ball — even on off-center strikes. This multi-thickness face profile is refined to maximise ball speeds across the entire hitting area for longer, more consistent distance with every iron in the set. A deeper centre of gravity and a higher moment of inertia further enhance launch stability and off-center forgiveness, delivering reliable, repeatable results without compromising the player's ability to work the ball when needed.
Mizuno engineers analysed head vibration patterns at the moment of impact to perfect both the feel and acoustic response of the MX SpeedMetal. The result is a network of six internal sound ribs integrated into the head structure, which are carefully tuned to produce a crisper, more solid strike sensation that instantly builds player confidence. The optimised head geometry works in harmony with these ribs to ensure every shot delivers the pure, satisfying feedback that Mizuno irons have always been known for. Rather than masking impact feel with excessive dampening, H.I.T. enhances and refines it — ensuring performance and sensation work together.
The MX SpeedMetal is finished in a premium nickel chrome plating with a refined satin treatment that elevates its on-course aesthetic. The satin surface dramatically reduces glare in bright sunlight, providing a clean, distraction-free view of the ball at address and throughout the swing. Beyond its visual appeal, the durable plating acts as a protective layer that resists everyday wear and tear, preserving the club's sharp, high-end appearance round after round. The result is a set of irons that looks as impressive as it performs — embodying Mizuno's commitment to craftsmanship in every detail.
