What the differences mean
At the 7-iron, the KING OS is 30° and the F-Max is 31.5°, a 1.5° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the KING OS should carry roughly 4 to 6 yards further with that club, on a slightly lower, shallower flight than the F-Max. Across the 9 clubs both sets share, the F-Max averages 0.9° weaker, with the largest gap at the 4-iron (20° vs 22°).
The KING OS is a game improvement iron and the F-Max a super game improvement iron, so they sit one step apart on the forgiveness scale. The F-Max is the more forgiving design, with a wider sole, more offset and more perimeter weighting for high handicaps, beginners and slower swing speeds. The KING OS trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly 10 to 25 handicaps.
The KING OS is listed as full-hollow cast body with tungsten toe weighting and the F-Max as investment cast cavity back with a deep undercut and progressive head construction. The KING OS's hollow body lets the face flex more and moves mass low and outward, usually giving higher launch and more ball speed on off-centre strikes than the F-Max, at some cost in feel. The KING OS adds tungsten weighting, which lowers the centre of gravity and raises stability on mis-hits, helping the long irons launch.
The F-Max arrived 1 year after the KING OS, a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept. Here the 7-iron loft moved from 30° to 31.5°.
Which should you choose?
The F-Max is the weaker-lofted set — up to 2° weaker than the KING OS. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.

Frequently asked questions
Is the Cobra KING OS stronger lofted than the F-Max?
Yes. The Cobra KING OS 7-iron is 30° against 31.5° for the F-Max, 1.5° stronger, which is worth roughly 4 to 6 yards of extra carry with the same swing.
What is the loft difference between the Cobra KING OS and F-Max?
At the 7-iron the difference is 1.5° (30° vs 31.5°). The largest gap on a shared club is 2° at the 4-iron, and 5 of the 9 shared clubs differ.
Which is better for higher handicap golfers, the Cobra KING OS or the F-Max?
The F-Max. As a super game improvement iron it is the more forgiving design, suited to high handicaps, beginners and slower swing speeds. The Cobra KING OS is a game improvement iron, better suited to roughly 10 to 25 handicaps.
Do the Cobra KING OS and F-Max have the same lie and length?
At the 7-iron, yes: both are 62.5° lie and 37.25 inches long.
