The Ai-ONE Milled Eight T S is a rounded progressive mallet with a slant neck, providing moderate toe hang that’s best suited for strokes with moderate 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.
Drop Ship Only
All golfers, even the best Tour 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 in Odyssey Ai-ONE Milled, we’ve leveraged Callaway’s industry-leading Artificial Intelligence design and super-computing capabilities to create a level of insert performance that no one else can match.
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 10% closer to the hole on average than a typical milled putter.
Ai-ONE InsertThis milled titanium insert was designed using Artificial Intelligence to create the unique contours on the back surface. These contours help to maintain ball speed on off-center hits for better distance control, no matter where you hit it on the face. The unique champagne finish complements the navy PVD of the head to give it a rich and striking look.
