Callaway GBB Epic Iron Sets Details

Every iron in this set is uniquely constructed to promote optimum performance. During development we studied and tested new ways to enhance launch and trajectory, and succeeded by introducing an incredibly high amount of MIM’ed tungsten (over 664 grams in the set) into our Internal Standing Wave technology. MIM’ed stands for Metal-Injected Molding, an injecting-molding process using finely powdered metal to create intricately shaped parts with tremendous precision.

Tungsten is relatively heavy, which allowed us to control the head’s internal weighting so that we could give each individual iron its own optimized 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 Irons.

Yet what truly sets this iron apart is the Exo-Cage head construction that we first applied to an iron in the Big Bertha OS, the only iron to earn five stars in every category of the 2017 Golf Digest Hot List. The high-grade steel structure in the center 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. In fact, it helped us raise the COR right up to the limit in each iron. We’ve never reached that level of speed in a full set.

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 result is the most premium, high-performance iron ever to bear the Callaway name.

  • Next generation 360 Face Cup Technology is 1mm at its thinnest point adding even more ball speed on center hits and further minimizing distance loss on off-center hits
  • Exo-Cage for Energy Lensing promotes faster ball speed for longer distance
  • Multi-Material standing wave optimizes CG location
