Callaway Quantum Max Iron Set (5 Clubs: 6–P) – N.S.PRO 950GH neo Steel Shaft

Greater Forgiveness and Spin with a 360° Undercut Structure

The Quantum iron series was developed with a focus on common impact errors often seen among average golfers. While continuing to use AI-designed models optimized for each club and loft, 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 off-center strikes such as low-face or toe-side impacts. This helps produce a higher launch angle and improves the chances of landing the ball on the green.

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

A newly designed Tri-Sole shape helps the club glide smoothly through the turf and reduces digging, providing improved turf interaction in a variety of impact conditions.

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

The Quantum Max Iron features a classic head size, shape, and offset, making it suitable for a wide range of players.
