Callaway Quantum Max Fast Iron Set (5 Clubs: 7–P, A) – N.S.PRO 950GH neo Steel Shaft

Large Head Packed with Technology for Distance and Forgiveness

The Quantum iron series was developed with a focus on common impact errors often seen among average golfers. While continuing to utilize AI-designed models optimized for each model and club number, a new 360° undercut structure has been introduced. The head features a cross-section shaped like the letter “J”.

By positioning the face weld point farther back from the face, the design allows the face to flex across a wider area—even on typical miss-hits such as strikes low on the face or toward the toe. This helps generate a higher launch angle and increases the chances of landing the ball on the green.

The irons also incorporate urethane microspheres, providing a high-quality sound and soft feel at impact.

A newly designed Tri-Sole improves turf interaction, helping the club glide smoothly through the ground and reducing digging regardless of the impact condition.

In addition, AI-engineered face design continues to be used, further strengthening control points and significantly enhancing trajectory correction.

The Quantum Max Fast Iron features a larger profile with an extended blade length, delivering excellent forgiveness and a strong sense of confidence for the player.
