RADSPEED Irons represent a breakthrough in golf technology innovation, with all new weighting technology and the first application of 3D printing in golf club design. An intricately designed lattice medallion is 3D printed and placed in the sole to save weight and fine-tune the feel. The extreme heel and toe weighting creates the optimal combination of speed, low spin and stability for the best performance. The forged PWRShell face insert increases flex in and around the sweet spot for faster ball speed and higher launch.


  • Radial Weighting – Strategic placement of weight optimizes speed, forgiveness, and flight direction. By increasing the distance between the front and back weights, Cobra created a radical combination of ultra low spin, extreme ball speed and forgiveness.
  • Extreme Heel and Toe Weighting – 10g and 3g weights positioned in heel and toe for fast ball speeds, low spin and stability.
  • Tuned RAD Weighting – 10g weight insert in the toe centers the CG and adds stability for better distance and forgiveness on off-center hits.
  • Forged PWRShell Face – Forged face insert is constructed with thin 17-4 stainless steel for increased flex at the sweet spot.
  • 3D Printed Medallion – Cobra has pioneered the introduction to innovation with the first application of 3D printing in golf club design: an intricate lattice medallion structure that saves weight and optimizes feel and sound.

Handicap: 0-5  Plays Golf: I play more than once a week  Dexterity: Right Hand

I traded my speedzones in to global golf and bought the new radspeed irons. Global Golf gave me a sweet deal with their 50% trade-in bonus. The irons were a big upgrade. I am able to crush my irons farther then ever before and they feel a bit lighter then the speedzones. The first time I hit my 6 iron, I crushed it 210yrds. Not something I was able to do with the speedzones. Love the clubs, and love global golf.
