The term D iron can cause a bit of confusion on the first tee, as it’s not a club you’ll find in a standard set. A D iron is more commonly known as a Driving Iron, a specialty club designed to be a powerful and reliable weapon from the tee. This article breaks down exactly what a driving iron is, who benefits from putting one in the bag, and precisely how to hit it for the best results on the course.
What Exactly Is a D Iron (Driving Iron)?
Think of a driving iron as the ultimate blend of a long iron's control and a fairway wood's forgiveness. It's a low-lofted, powerhouse iron specifically built to offer a strong, piercing ball flight for players who need an accurate alternative to their driver or 3-wood. It’s the "fairway finder" many golfers turn to when a hole gets tight and a fairway hit is non-negotiable.
For decades, professional golfers and skilled amateurs carried 1-irons and 2-irons for these types of shots. However, these traditional long irons were notoriously difficult to hit. They had tiny sweet spots and required immense swing speed and perfect contact to get airborne. For the average player, they were often more trouble than they were worth.
The modern driving iron solves this problem. It packs the same low loft as those old blades but with an infusion of modern technology that makes it significantly easier to launch and far more forgiving on off-center strikes. It’s designed to look like an iron and feel like an iron at address, giving comfort to players who prefer that look over a bulkier hybrid or wood.
Driving Iron vs. Hybrid vs. Fairway Wood
It’s helpful to understand where the driving iron fits in the golf bag ecosystem. Here’s a quick comparison:
- Driving Iron: The lowest-launching and lowest-spinning of the three. It produces a penetrating ball flight that's fantastic for windy days and firm fairways where you’ll get plenty of roll. It offers maximum control and workability for shot-shapers but is generally the least forgiving.
- Hybrid: The versatile middle ground. Hybrids are designed to be a direct replacement for long irons, offering a higher launch and more spin than a driving iron. Their shape helps them cut through rough more easily, making them a better all-around option from various lies. They are built for forgiveness and getting the ball up in the air easily.
- Fairway Wood: The highest-launching and most forgiving option of the group. With a larger head and deeper center of gravity, a fairway wood is designed for maximum distance and forgiveness. It’s easier to hit high from both the tee and fairway, but that higher flight can be a disadvantage in the wind and offers a little less precision than an iron.
The Anatomy of a Driving Iron
What makes a driving iron different from a standard 3-iron? It all comes down to the design philosophy. Engineers have taken the profile of a long iron and supercharged it with technology borrowed from metalwoods.
Clubhead Construction
Most driving irons feature a hollow-body construction, much like a metalwood. This allows the face to flex a lot more at impact, which creates higher ball speeds across a wider area of the face. This is the main source of its forgiveness compared to a traditional, solid-piece long iron. The hollow body also allows manufacturers to place weight strategically around the perimeter and low-in-the-sole to lower the center of gravity (CG), making it easier to launch the ball high.
Wide Sole Design
You'll notice that driving irons have a wider sole (the bottom of the club) than a standard iron. This serves two purposes. First, it helps prevent digging into the turf on shots from the fairway, allowing the club to glide through the grass more smoothly. Second, that extra mass low in the head further helps lower the CG, assisting with a higher launch angle.
Loft and Shaft
Driving irons typically have lofts ranging from 16 to 22 degrees, which puts them in the same neighborhood as a 2, 3, or even 4-iron. Shaft offerings are also different. While you can find them with graphite shafts, many stronger players opt for heavier steel shafts (or heavy graphite) to increase control and promote that piercing, low-spin ball flight they are looking for.
Who Should Carry a Driving Iron?
While technology has made the driving iron more accessible, it’s still a specialty club that suits a specific type of player. It’s not the best choice for everyone.
Players with Above-Average Swing Speed
Let's be direct: to get the most out of a very low-lofted club, you need speed. Without enough clubhead speed, you'll struggle to generate the height and carry distance needed to make the club effective. Players who swing their driver at 100 mph or more will usually see the most benefit, as they have the power to activate the club's design and launch the ball on a strong trajectory. Golfers with slower swings are often better served by the higher launch of a hybrid or fairway wood.
The Golfer Seeking a "Fairway Finder"
This is the number one reason to bag a driving iron. If your driver gets a little wild or you face doglegs and tight landing areas, a driving iron is your best friend. It provides significantly more control than a driver while still offering plenty of distance to leave you with a reasonable approach shot into the green. Hitting the fairway more often keeps those dreaded double bogeys off the scorecard.
Excellent for Windy or Firm Conditions
If you regularly play in windy conditions or on firm, links-style courses, a driving iron becomes almost a necessity. Its low, penetrating flight stays under the wind, minimizing its effect on the ball. On firm ground, the ball will land and roll out for a considerable distance, often rivaling the total distance of a high-flying 5-wood.
For Those Who Prefer the Look of an Iron
Some golfers simply do not like the look of a hybrid at address. Personal preference plays a huge role in confidence, and if you feel more comfortable standing over a club with an iron profile, the driving iron is the perfect fit. It delivers hybrid-like forgiveness in a package that looks and feels like a classic iron.
How to Hit Your Driving Iron: A Coach's Guide
Hitting a driving iron correctly involves a slightly different approach depending on whether you're on the tee or in the fairway. Let me walk you through the proper technique for both.
Method 1: Hitting the D Iron from the Tee
This is the driving iron's bread and butter. Your goal here is to hit the ball with a slightly ascending attack angle, similar to hitting a driver or fairway wood.
- Tee Height: Use a short tee and set the ball up low. You want about half of the ball to be above the top edge of the clubface. This promotes a slight upward strike.
- Ball Position: Place the ball slightly forward in your stance. A good reference point is about two ball-widths inside your lead heel. This is further back than your driver but further forward than a standard mid-iron.
- Stance: Take your normal, stable stance, about shoulder-width apart. Don't feel the need to stand extra wide.
- The Swing Feel: Think about sweeping the ball off the tee. The forward ball position will help you catch it on a shallow, almost level path. The big mistake players make is trying to "help" the low-lofted club get into the air by scooping it. Trust the loft. Just make a smooth, balanced swing and the club will do the work.
Method 2: Hitting the D Iron from the Fairway
Hitting a driving iron off the deck is a much more demanding shot and requires precise contact. Make sure you have a good lie before attempting it.
- Ball Position: Move the ball back to the center of your stance, or just a touch forward of center. This is the spot where you would play a standard 3-iron or 4-iron.
- Get Your Weight Forward: At address, feel like about 60% of your weight is on your lead foot. This prepares your body for the correct impact position.
- The Swing Feel: Unlike the tee shot, you need to hit down on the ball just like any other iron shot. The goal is to make contact with the ball first, then the turf. This downward strike is what compresses the ball against the clubface, producing the ideal spin and launch. Keep your weight moving towards the target through impact.
- Manage your Expectations: This shot isn't meant to fly super high. Expect a low, running trajectory that covers a lot of ground. It’s a great shot for long approaches into open greens, but probably not the best choice when you need to carry a bunker and stop the ball quickly.
Final Thoughts
The D iron, or driving iron, is a fantastic specialized club that can add a new dimension of control and reliability to your tee game. For players with enough speed who are looking for an accurate fairway-finder, especially in windy or firm conditions, it can be a true score-saver by keeping you in play.
