Odyssey Ai-ONE Silver Milled SEVEN T CH putter 2025

Now in a beautiful silver finish, the Ai-ONE Silver Milled Seven T CH is an updated take on this iconic design featuring a crank hosel that provides moderate toe hang — making it best suited for golfers with a moderate arc and moderate face rotation through impact. The Seven T head shape combines an angular, easy-to-align mallet silhouette with tour-level craftsmanship: the entire body is precision-milled from stainless steel and fitted with a 100% milled titanium Ai-ONE insert engineered with artificial intelligence. The putter ships with the new Odyssey SL 90 Stroke Lab steel shaft and includes a matching headcover.

Technology in Detail

Ai-ONE Milled Insert

The heart of the Ai-ONE Silver Milled Seven T CH is its 100% milled titanium insert, designed from the ground up using Callaway's artificial intelligence and super-computing capabilities. The AI created unique contours on the back surface of the insert — contours that no human engineer would likely arrive at through conventional design methods. These contours act as a variable-thickness structure that flexes intelligently across different impact locations, helping to maintain consistent ball speed whether you strike the center, heel, or toe of the face. The result is better distance control on every putt, regardless of where contact is made, and putts that finish closer to the hole on average compared to a typical milled putter.

100% Milled Stainless Steel Construction

The body of the Seven T CH is precision-milled from a solid block of stainless steel, a process that removes material with extreme accuracy to create perfectly consistent geometry from head to head. Full milling is the gold standard of putter manufacturing, delivering the exacting tolerances and premium tactile feel that tour professionals and serious amateurs expect. Every surface — sole, cavity, hosel, and face perimeter — is shaped to exact specifications, ensuring that the head weight of 360 g and the loft and lie angles are precisely replicated. The silver finish is applied after milling, providing a clean, classic, and highly premium look.

Crank Hosel (CH) & Moderate Toe Hang

The crank hosel is a distinctive neck design in which the shaft is offset forward and then angled back over the head, creating a specific balance point and toe hang measurement. On this model, the result is a 21° toe hang — classified as moderate — which means the toe of the putter drops slightly when the club is balanced on a finger along the shaft axis. This moderate toe hang is best matched to golfers whose putting stroke follows a slight arc, with a corresponding degree of face rotation through the ball. For golfers who use a more straight-back-straight-through stroke, or who rotate the face more aggressively, other hosel configurations (double-bend or slant neck) may be better suited. The full-shaft offset also helps position the hands slightly ahead of the ball, promoting a forward-press that assists in a smooth, rolling start to the putt.

SL 90 Stroke Lab Steel Shaft

The Odyssey SL 90 Stroke Lab steel shaft is a lightweight steel shaft designed specifically for putting. It incorporates 20–30 grams of counterbalance weight in the butt end (the exact amount varies depending on grip choice), which shifts the overall balance point of the club higher up the grip. This counterbalance effect reduces the perceived weight of the head during the stroke, making it easier to control tempo and arc. The Stroke Lab shaft is an evolution of the original graphite-and-steel composite Stroke Lab concept, now delivered in a pure steel shaft construction that gives players the classic feel of steel with improved weight distribution. The shaft is compatible with the removable sole weights (available in 5, 10, 15, and 20 grams) that allow further fine-tuning of head weight to individual preference.
