These incredible irons have been created with loads on innovation without boundaries. The Callaway designers have elevated themselves into producing an iron to the highest level in a compact players shape. It combines the combination of ball speed, distance, forgiveness, accuracy, control and feel. And to go beyond that standard, they have had to be extremely meticulous, creative and committed to carefully crafting each material.
This exceptional iron set also features:
- Next-Generation 360 Face Cup Technology
- Exo-Cage for Energy Lensing and Maximum COR
- MIM’ed Tungsten Infused Standing Wave To Optimise CG Location
- 1 year guarantee
The Face Cup incorporates an ultra-thin rim around the perimeter of the inner side of the face. At impact, the rim flexes and rebounds to add ball speed on centre-face hits and minimize ball-speed loss on off-centre hits. It’s especially effective on the most common mis-hits -- toward the toe and low on the face. To further improve face performance, this iron has an increased rim flexibility by reducing the thickness to 1 mm at its thinnest point, resulting in even faster ball speed on centre and off-centre hits for more distance.
Every iron in this set is uniquely constructed to promote optimum performance. During development stages, Callaway's engineers studied and tested new ways to enhance launch and trajectory, and succeeded by introducing an incredibly high amount of MIM’ed tungsten (about 621 grams across the set) into our Internal Standing Wave technology. MIM’ed stands for Metal-Injection Moulding, an injection-moulding process using finely powdered metal to create intricately shaped parts with tremendous precision.
Tungsten is relatively heavy, which allowed the designers to control the head’s internal weighting so that we could give each individual iron its own optimised CG location. To do this, we engineered a precise amount of tungsten for each club. We could lower the CG in the long irons for easy launch and high, long carry, and raise the CG in the short irons for lower, more controllable flight. And we could better control the left-right CG positioning in tandem with the hollow hosel that creates weight savings. This is an expensive alloy to manufacture, but it’s integral to enhancing performance in the Epic Pro Irons.
Yet what truly sets this players iron apart is the Exo-Cage head construction. The high-grade steel structure in the centre of the cavity stiffens the body, especially the topline and sole, so that the face can take on more impact load. This is known as “energy lensing”, and in the irons energy lensing allows the face to behave more efficiently to promote faster ball speed and distance, dramatically enhancing performance. This has helped raise the COR right up to the limit in each iron. It’s the highest level of ball speed and forgiveness enhancing technologies that Callaway have ever achieved in a pro head shape. The multi-material head consists of a variety of premium components, each precision-milled and robotically laser-welded to give Callaway engineers precise control over CG location, COR, MOI and vibration control, with maximum structural integrity. A multitude of processes, steps and inspections are required to create each head.
The slightly smaller head, slimmer topline, and less offset all promote the kind of keen feel and workability that better players want. The result is the most premium, high-performance iron ever to bear the Callaway name.
