Whether you are in the beginning stages of choosing golf irons, or you have narrowed down your list and want the low down, my review of the Titleist 620 CB irons will provide you with all the information to decide if these are the ones for you.
For those who are just getting into golf, irons are one of those essential pieces of equipment that every golfer needs. They make up the majority of your set of clubs and will be the foundation for your entire game. Having irons that fit your swing and skill level is critical to becoming a better golfer.
Titleist CB 620 Irons Features
The “CB” in the name of these irons stands for cavity back, making them one of the most visually appealing forged cavity backs on the market. These are considered a players’ iron, names as such because they are more geared towards players with some skill and experience in the game. A players’ iron offers less forgiveness than a game improvement iron, but gains control of shot shaping and distances.
Innovative Design

The design of the CBs is simple and elegant. There is not a lot of fancy technology built in, just tried and true designs that create a beautiful combination of appearance, exceptional feel, and forgiveness.
The irons are built with a cavity that sits high on the back of the club head, moving the center of gravity down and back for more forgiveness, as well as perimeter weighting that cranks up the moment of inertia.
Premium Forged Feel

I love forged irons. While they produce more vibration on mishits, the feeling of hitting a forged iron in the middle of the face will never get old.
If you have ever hit a ping pong ball with a golf club, that is kind of what it feels like to hit a forged club pure. It’s almost like swinging through a cloud, only to look up and see your golf ball flying towards the target. Of all the forged irons I have hit, the Titleist 620 CBs give the most pleasing feel.
The big downside of forged irons is how quickly they wear out. Due to the integrity of the metal and the forging process, a forged iron like the CBs wears out a lot more quickly than a cast iron. Forged irons are also much more susceptible to rust than their cast counterparts. These are simply sacrifices you have to face for a higher performance iron.

No one cares about looks and feel if an iron doesn’t perform. I’m here to tell you that the CBs absolutely do. When I first switched to them, I was a little nervous that they wouldn’t perform to the standard that I had grown accustomed to with my Cobra irons.
Without doing anything different in my practice, my swing, or my coaching, I immediately started hitting more greens and giving myself closer birdie putts. The fact of the matter is that the CBs just seem to work.
Head Shape

Here is one of the things I love the most about the CBs. The club head almost looks like a blade from the top view, while still performing like a classic cavity back design, similar to the Mizuno MP 15 Irons.
I love the progressive blade length. I feel more confident with the smaller short irons and the larger long irons.
The topline is narrow and easy to look at, giving the feel of a club that tour players can trust - which they do, both men and women on tour.
I also love the reduced offset. It is minimal for a non-blade iron, giving these clubs a very straight faced, reliable feel. It should be noted that lack of offset is not a good feature for any golfer who struggles with a slice, but the same feature allows a good player to hit the shots they need.
Complete Set Makeup

The Titleist 620 CB irons are made in pitching wedge all the way up to 3 iron. I personally have the entire set, although most players cut off at 4 or 5 iron, as hybrid irons have become so easy to hit.
The set extending to 3 iron is a bit rare in the golf industry nowadays. I think it’s a great option to give to players who may prefer a long iron over a hybrid or a high lofted wood. The more customizable, the better!
Workability

As we are talking about players of a higher skill level, it is likely that this same demographic wants the ability to hit a variety of shot shapes. Whether for fun or to get out a tough situation, being able to effectively curve the ball both ways with a high level of control is an incredibly useful skill.
First and foremost, in order to work the golf ball you must keep your clubs clean.
The CBs offer this ability for 2 major reasons. First, forged irons tend to impart more side spin on the golf ball due to simple design characteristics. While this would be a bad thing for a player without the ability to control the club face, it can be very useful for someone who wants to curve shots.
Second, a players’ iron is going to have less weight built into the perimeter of the club head, meaning a lower moment of inertia and higher gear effect. These terms likely don’t mean anything to you, so to put it differently, the club does not work against the golfer trying to hit a hook or slice.
There are some clubs, called game improvement irons, that are actually designed to help you hit the ball straight. Those clubs have what we call low workability, and are the contrast to the Titleist 620 CB irons.
Forgiveness

Forgiveness is something that is sacrificed to a degree when you choose to go with a players’ iron. It’s an unfortunate truth that is universal in golf - any iron that is designed for tighter control is not going to provide as much help when you mishit a shot.
When it comes to players’ cavity backs, the CBs are one of the most forgiving on the market. The cavity being placed higher on the club head helps the center of gravity of the club move further down (where the denser material is), making it easier to get the ball in the air. Titleist has also found a way to forge a thin face with lots of material around the edges of the club head, helping maintain ball speed even when struck off center.
Neither these nor any other players’ iron is going to be as forgiving as something like a Taylormade M4 iron, which is designed for forgiveness and utility. This is why we recommend the CB 620’s for players who consider themselves strong ball strikers. If you are looking for forgiveness in a Titleist iron, take a look at the T300 Irons.
Handicap Range
Given the lack of forgiveness relative to game improvement irons, and the increased workability of these irons, I believe they are best suited for players whose handicap is under 5. From a scoring standpoint, this would mean your scoring average sits somewhere around 76-78, and your wider scoring range is between 74-83. Of course, if you are shooting better scores than this the Titleist CB 620’s are still a good iron for you.
Our Experience Using The Titleist 620 CB Irons

As you can probably tell from everything I have said so far, my experience with the CBs has been nothing short of amazing. Prior to switching, I tested everything from Mizuno to Srixon to Taylormade to Miura, and nothing compared to the balanced performance of the CB 620’s. Some irons may have provided more forgiveness, but they were very hard to work. Others gave me more total distance, but it was hard to hit specific yardages. I can say for certain that the CB 620 irons from Titleist are the cream of the crop. But above it says “our experience,” so let me tell you what my brother has to say about the CBs.
John has been using them longer than me, and he has a pedigree of success that most of the world would pay good money for. He is an NCAA National Champion, has multiple top 5 finishes on the Korn Ferry Tour, and has experienced early success on the PGA Tour. He has gone as far as to test other Titleist irons like the T100s, and swears that it would take a lot of convincing to get him to switch away from CBs.
The short version is this - we love the Titleist 620 CB irons. They are a great balance of reliable performance, good looks, and impeccable feel. We have experienced an impressive level of consistency through multiple sets of CBs. My bet is we will continue to trust these irons for years to come.

Final Thoughts
If you are a higher level player - from a weekend warrior shooting 75 to a competitive player with a “+” in front of your handicap - the Titleist 620 CB irons are a phenomenal option. While they are not the longest iron, the most forgiving, the highest launching, or the most technologically advanced, they are the ultimate balance of all of those things.
Here’s the thing about the CB 620’s - if they are the right iron for you, then you know your numbers, you’re confident that you hit them far enough, and you feel like you strike the ball solid most of the time. If this describes you, chances are you are the perfect player to have a set in your bag.
There are some with more speed, more height, more forgiveness, or more workability, but there are none that give you all of these characteristics in noticeable amounts. I am confident that, if you give the Titleist 620 CB’s a chance, you will never use another iron in your life. At least until the years catch up with you and you need a little help getting the ball to the green!
