The Ai-ONE MILLED SEVEN T DB is an updated take on this iconic design with a Double Bend shaft. It’s a face balanced offering that’s best suited for strokes with minimal arc and face rotation. This putter is milled out of stainless steel and fitted with our milled titanium Ai-ONE insert and features our new SL 90 Stroke Lab steel shaft.

All golfers, even the best players in the world, miss the center of face from time to time. And when you lose speed relative to a center hit, the ball doesn’t roll as far as you intended, so you miss more putts or leave them farther from the hole. Now with Ai-ONE Milled, we’ve leveraged Callaway’s industry-leading Artificial Intelligence design and super-computing capabilities to create the most advanced insert in golf, with consistent ball speeds across the face.

These premium putters feature a 100% milled stainless steel body fit with a 100% milled titanium insert. The multi-material construction includes unique contours on the back of the face that minimize ball speed losses on off-center hits, and greatly increase the sweet spot. With Ai-ONE Milled, putts finish closer to the hole on average than a traditional milled putter.

These new models deliver the premium look and feel that players expect with a level of insert performance that no one else can match. This is the new face of milled design putters.
