The Cobra BiO Cell irons feature a perimeter undercut cavity design and tungsten weights strategically positioned to produce a combination of forgiveness and explosive distance. They feature BiO Cell technology which re-distributes weight from the face and body to increase perimeter weighting and positions the center of gravity directly behind the sweet spot. This iron features Cobra’s largest unsupported face ever to create incredible face flex delivering increased ball speeds and maximum distance. E9 Face Technology and metalwood face-weld construction combine to create a higher COR for increased distance and forgiveness. The long irons (3 through the 7 iron) feature a hyper 17-4 stainless steel construction with heel - toe tungsten weighting for incredible forgiveness, while the short irons (8 iron and shorter) have a 431 stainless steel construction with tungsten weighting centered behind the hitting area for added distance.


  • Perimeter Undercut Cavity design: The BiO Cell iron has the largest unsupported face of any COBRA iron and this head design creates more face flex at impact for extreme distance and higher ball speed.
  • Forged E9™ and BiO Cell Face Technology: With new BiO Cell pockets combined with E9 Face technology, Cobra has removed weight from the face which delivers a larger effective Sweet Zone™ which produces faster ball speeds for longer and straighter drives.
  • Tungsten Weight Fueled Distance and Forgiveness: The long and mid irons (3-7 irons) feature heavy tungsten in the heel and toe for added forgiveness while the short irons feature tungsten weighting centered behind the hitting area for improved distance an

GREAT Iron set

As expected with most Cobra products, the Bio Cell line is an amazing representation of Cobra quality. The clubs arrived before promised date and in better than new condition. Not only extremely happy with clubs, but with my experience with Global Golf as well.

Used Bio Cells From Global Golf

Handicap: 21+  Plays Golf: I play monthly  Dexterity: Right Hand

I purchased Used Excelled Condition Bio Cell Silvers 4-GW after hitting them in a local Big Box store. The irons I hit were very forgiving, long and straight.

Bought Sun 12/28/14, delivered today Wed 12/31/14

I am disappointed in the rating system Global Golf used, as some of this set should fall safely in Very Good Condition and not Excellent. There is a dent in the cover on the cavity back that says Tungsten Weighting on the 4 iron, small nicks/gouges on the bottom face of the 9 iron and deformities (dents/scrapes) in the grooves on another iron. There is much more than ball marks on the face of all these clubs. Each face is scratched and scuffed. The rating of Excellent would apply to some of the clubs, but definitely not all. These were played a good amount and not babied clubs.

Beware that the rating used for a used set you buy, might not apply to all of the clubs in the set.

They will function fine, but show more wear than what is listed in description and video of Excellent Irons.
