Guide: Driving Iron – A Safe Choice for Hitting the Fairway

Driving irons, also known as utility irons, close the gap between irons and fairway woods. They are becoming increasingly popular. The fitting experts at HIO Fitting explain why this alternative to hybrids can be an advantage in the long game.

Guide: Everything you need to know about the driving iron

Strong performance from the tee box

Driving irons have long been established among professionals, but they are also becoming increasingly interesting for amateurs. In the following, the experts from HIO Fitting show how these clubs work, who they might be suitable for and which models are currently in vogue.

Driving irons: efficiency and control

Long irons have always been difficult to play, which is why many golfers prefer to use hybrids or woods. However, for those who prefer the classic look of an iron, driving irons could be the solution. These clubs combine the traditional style of an iron with modern technologies to increase forgiveness and make longer shots easier. Most utility irons also use graphite shafts, which allow for easier acceleration of the club head. This combination of components and special technologies is intended to make driving irons easier to play.

Technology and construction

Driving irons initially have a wider profile in order to distribute more weight in the edges and on the underside of the club head. This increases forgiveness and makes it easier to launch the ball. Modern models are also often equipped with cavity technology and special fillings to improve club head speed and sound. The chosen head shape thus supports a ball flight with less spin, which achieves more distance due to the flatter flight curve and longer roll.

Target group and use

Driving irons tend to fly flatter than hybrids and are particularly suitable for tee shots. They can also be used for shots into the green, but this requires high swing speeds and therefore high ball speeds in order to achieve a higher ball flight and less roll. Players who often play from the fairway or semi-rough into the green and want a club that is easier to play than a long iron and also generates more spin may be better off with a hybrid.

Example models based on TaylorMade

Different manufacturers use different technologies in the development of their utility irons. Which of the models is best suited to individual use should therefore be analyzed as part of a professional club fitting. In the following, the experts from HIO Fitting present different concepts of driving irons based on three TaylorMade models.

TaylorMade has three clubs in its range that fall into the category of driving irons: the P UDI, the P DHY and the new P790 UDI. The abbreviation UDI stands for Utility Driving Iron, which means that TaylorMade strategically covers both common names for this category of clubs. While the P790 UDI is still very reminiscent of a traditional iron, the other two clubs in the P family are characterized by more exotic designs. The P DHY is more like a hybrid and is therefore also referred to as a driving hybrid. The P UDI, on the other hand, has a futuristic, thick and powerful design. All models promise increased precision and optimum trajectories with maximum forgiveness.

The fitter’s view on driving irons

So much for the theory, but practice can differ considerably. Thanks to 15 years of fitting experience, the HIO experts have been able to accompany countless customers in their search for the perfect golf clubs. There are always people who would like to play a driving iron, after all, its characteristics sound quite conclusive and also advantageous in many aspects. Already during the fitting, or at the latest out on the course, fitters notice that utility irons perform worse than hybrids in one area in particular, namely when it comes to the forgiveness of the club types. A driving iron is significantly more difficult to hit, flies flatter and is not as consistent behind the ball as the hybrid. The typical slice is also amplified with a driving iron. The hybrid, on the other hand, has a natural draw tendency, which benefits many golfers, especially in the long transport clubs. For these reasons, the experts at HIO Fitting find that driving irons are by far the least used and fitted clubs at HIO, as most fitting customers are won over by the strong performance of hybrid clubs.

Nevertheless, the experts can draw important conclusions for the iron game from the technology of the driving irons: In general, a wider iron is always advantageous to approach precision play with even more control. It can also be helpful to use a wider model in the long 5 or 4 irons in order to increase forgiveness. Ultimately, the clear advantage of graphite shafts can also be seen in the irons, as the club is easier to move without compromising precision – even for athletic players.

To summarize, driving irons are an interesting alternative to hybrids, especially for players who prefer the classic look and controllability of an iron. Utility irons are characterized by their special design, which is intended to improve precision and fault tolerance. However, hybrids often offer greater forgiveness and consistency, making them the more popular choice for most golfers. Ultimately, however, it all comes down to individual playing style, which is why a professional fitting is essential to find the club that best suits your needs.

Equipment: The Buyer’s Guide to the Perfect Golf Shaft

Acting as the “engine” of the golf club, the shaft forms the crucial connection between the clubhead and the golfer. Its length, flexibility, kick-point, weight, and alignment profoundly influence the club’s performance, warranting a thorough examination. Our experts at HIO Fitting are here to provide detailed insights.

Types of Golf Shafts

Golf shafts come in many types and subtypes, each with distinct properties affecting the game. Modern shafts are typically made from steel, graphite, or composite materials.

The Difference in Shaft Material: Steel or Graphite

The notion of “precision with steel vs. speed with graphite” is debunked by HIO Fitting experts. Golfers comfortable with graphite shafts will achieve precise shots, and those handling steel’s weight won’t necessarily swing faster with lighter graphite shafts. The increased swing speed associated with lighter shafts is due to their reduced weight, not their material.

Technological advancements from 2000 to 2015 have nullified the old belief that steel shafts offer more precision. Graphite shafts now dominate woods, while steel shafts are still preferred in hybrids for power players. The advantage of graphite in long clubs lies in their lighter weight and customizable profiles.

Steel Shafts

Heavier and stiffer, steel shafts suit players with high swing speeds and are cost-effective to produce. Typically weighing between 90g and 130g, they offer flexes from Regular to Extra Stiff (R-X). Though technically feasible, making steel shafts lighter and softer is prohibitively expensive.

Graphite Shafts

Our HIO Fitting experts dispel common myths about graphite shafts:

  • Graphite shafts are durable and don’t wear out or become fatigued.
  • Modern graphite shafts offer stability and precision even for high swing speeds.
  • They provide a consistent feel, ideal for perfect iron sets.

Graphite shafts are manufactured by wrapping graphite tape with epoxy resin around a steel spindle. After heating, the spindle is removed, and the shaft is ground, cut, and painted.

The primary advantage of graphite shafts is their low weight. Available from 29 grams in woods to 39 grams in irons, they can also weigh up to 125 grams, matching steel shafts in weight. Graphite shafts cater to all flex variants, from “Ultra-Light” to “X-Stiff,” accommodating every swing speed. They are also beneficial for golfers with joint issues due to their vibration dampening properties and can be customized to individual preferences.

Multi-Material Shafts

Multi-material shafts, which emerged in the mid-2010s, combine the best properties of steel and graphite, revolutionizing irons and wedges. New methods to incorporate steel fibers into graphite have made these shafts stiffer and lighter.

High-End Carbon Fibers

Innovations in the 2020s have introduced pure graphite shafts with advanced carbon fiber structures, like Mitsubishi Chemical’s “Braided Carbon Technology,” integrating new fibers like 1K Carbon Fiber or MR70. These shafts achieve high stiffness at low weights, with some as light as 30 grams or customizable in weight distribution.

Key Golf Shaft Terminology

What is Flex?

Flex refers to the shaft’s ability to bend, categorized into Ladies/Light (L), Amateur (A), Senior (S), Regular (R), Stiff (S), and Extra Stiff (XS). Flex levels vary by manufacturer, lacking a unified standard. Flex is measured by the shaft’s vibration frequency (CPM) before installation. During fitting, stiffness is adjusted by trimming the narrower end (tip trimming).

The Impact of Flex on Ball Flight and Feel

A shaft that’s too soft bends excessively, resulting in higher trajectories and leftward spins, while a stiff shaft does the opposite. However, HIO Fitting experts note that these effects vary among golfers. During fitting, flex is tailored to swing speed and golfer development, with a focus on feel and control.

Driver Distance and Corresponding Flex

  • Ladies Flex: Driver distance less than 175 yards (160 meters).
  • Senior or A Flex: Driver distance 175 – 210 yards (160 – 190 meters).
  • Regular Flex: Driver distance 210 – 240 yards (190 – 220 meters).
  • Stiff Flex: Driver distance 240 – 275 yards (220 – 250 meters).
  • X-Stiff Flex: Driver distance over 275 yards (250 meters).

What is Torque?

Torque measures the shaft’s twisting under load, impacting the clubface on off-center hits. Lower torque means less twisting but a stiffer feel, potentially losing feedback and distance. Finding the right torque value is essential for individual swing speeds.

What is a Kick-Point?

The kick-point is where the shaft bends most during a swing, influencing feel and ball flight trajectory. High kick-points result in lower ball flights, while low kick-points lead to higher trajectories.

The Weight of the Shaft

Shaft weight, measured in grams, affects clubhead speed and distance. Lighter shafts increase speed, while heavier ones provide stability. Proper weight distribution can significantly improve coordination and reduce mishits.

The Length of the Golf Shaft

Correct shaft length, determined by measuring the wrist crease to the ground, is crucial. Longer shafts increase distance but require repeatable, solid shots for consistency. Accurate fitting prevents distance loss due to off-center impacts.

Better to Get Fitted Than to Guess

Fitting, once exclusive to tour players, is now widely accessible. An experienced fitter can demystify shaft selection through a comprehensive fitting process, including static and dynamic fitting, ball flight analysis, and personalized adjustments.

How Can the Right Shafts Improve Your Game?

Hitting Further

A lighter shaft or optimized ball flight parameters through dynamic fitting can increase distance.

Hitting Straighter

A stiffer or heavier shaft can reduce dispersion, but lab conditions are recommended for comparison. Properly bent angles in irons and wedges also help.

Hitting Higher

Light shafts with low kick-points or heads with deep, rearward centers of gravity produce higher flights through increased backspin.

Hitting Lower

Heavy shafts with high kick-points or heads with forward centers of gravity achieve lower flights with reduced backspin.
