Q&A: Aerotech Golf President Chris Hilleary



The best-case scenario for a small golf equipment company is essentially what has happened for Aerotech Golf in the last six years.

Matt Kuchar began using a set of the company’s SteelFiber composite shafts in his irons in 2008. Since the switch, he’s won five times on the PGA Tour, and along the way he convinced friend and fellow top-ranked golfer Brandt Snedeker to try the shafts. Snedeker liked them so much that he put the same model in his irons, and has used them in route to four PGA Tour wins as well as the 2012 FedEx Cup.


The success of Kuchar and Snedeker has led to several other PGA Tour winners using the shafts, but what seems like an overnight success actually began 17 years ago.

Aerotech Golf President Chris Hilleary joined Aerotech Sports in 1997 as the director of its golf division. The company’s main focus was the production of composite hockey sticks, however, which allowed Hilleary to purchase the golf division in October 2005.

Since that time, Hilleary has grown the Bellingham, Wash., company to an enviable spot in the industry. SteelFiber is the No. 1 graphite iron shaft on the PGA Tour, and its popularity with golfers has led to it becoming a custom iron shaft option for nearly every major equipment manufacturer.

Hilleary took the time to chat with GolfWRX Managing Editor Zak Kozuchowski about the SteelFiber shaft, his company’s success and what the future holds for Aerotech.


ZK: Chris, you said that you strapped yourself financially to purchase Aerotech Golf in 2005. What was it that made you do that?

CH: I worked for Aerotech Sports (Aerotech Golf’s parent company) for nine years and ran its golf division. During that time, I designed the SteelFiber technology and I knew that this shaft had the potential to revolutionize the iron shaft category. When the opportunity to purchase the golf division came along, I actually had to compete against one of the largest shaft manufacturers in the world to purchase the brand. I initially looked for investors, but I decided to leverage everything I owned and was able to outbid the competition. In retrospect, it was one of the smartest decision I’ve ever made.

ZK: Tell me about the SteelFiber shaft specifically. Where did the idea come from, and why do you think that it has been so successful?

CH: Before I began designing the SteelFiber shaft, I saw a void in the market as composite shafts had not been embraced in the iron category. Over 95 percent of all drivers and fairway woods used graphite at the time and I was confident iron shafts would get there, but I needed to overcome some performance hurdles first. That’s when I set out to create a graphite iron shaft that had all the control and consistency of steel but had all the benefits of graphite as well. The SteelFiber shaft was actually an evolution of several designs over time. Early on in the development I realized that I needed to add a higher density (heavier) material into the structure to achieve the performance enhancements I was looking for. After several attempts co-mingling different materials with the graphite the real breakthrough came when I discovered the micro-thin steel fiber and applied it to the entire surface of the shaft. The unique combination of the graphite core with the full layer of steel has created an iron shaft that outperforms steel shafts that has ultimately accounted for its success.


ZK: What do golfers need to know about SteelFiber shafts if they’re considering purchasing a set? I’ve been told by top custom fitters that the shafts tend to play on the stiff side and that they have a higher balance point than a lot of iron shafts.

CH: First of all, golfers should understand that this is a composite shaft so it has all the vibration-dampening characteristic of a 100 percent graphite shaft. This lowers the risk of injury, aggravation of existing injuries and reduces the fatigue associated with swinging heavier, harsher steel shafts. Secondly, we have designed this shaft with a very stable lower quadrant and tight torque values. Combine that with the full layer of steel and it results in an extremely controllable shaft even as the butt frequencies get lower (softer). Therefore, the shaft plays on the firm side of flex as you mentioned. This is evidenced by that fact that over 80 percent of all the shafts being played on the PGA and Champions tours are our standard stiff flex. Our balance points run about 50 percent (middle of the shaft), which is not necessarily high but when using lighter weight shafts with standard head weights (designed for building steel shafted irons) a club builder may need to add a tip weight or make a slight length adjustment to hit target swing weights.

ZK: When an iron shaft becomes successful on tour, it tends to be successful for a long time. For example, True Temper’s Dynamic Gold steel shafts have been the most played iron shafts on the PGA Tour for decades. Do you think SteelFiber has that kind of staying power?

CH: The Dynamic Gold has been the benchmark in iron shafts for more than 70 years and we can only dream that the SteelFiber shaft has that kind of staying power. With that said, the Dynamic Gold shaft replaced the hickory shaft because of the performance benefits it exhibited over its predecessor. The SteelFiber has now taken iron shaft performance to the next level by adding performance characteristics that the steel shaft could not achieve. If history repeats itself, you never know, the SteelFiber shaft has a chance to become the new “gold standard.”

ZK: Some large golf equipment manufacturers have expressed their frustration with USGA rules that they say have limited innovation. Do shaft manufacturers face similar obstacles, or is there still a lot of room to innovate in the shaft space?

CH: I think the golf shaft is one area that can continue to stretch the boundaries of performance and make the game more enjoyable for everyone. As material science, manufacturing processes and the understanding of shaft performance improves, we will continue to create new innovative designs.

ZK: Tell me what’s next for Aerotech Golf.

CH: Our main focus has been managing the growth that we’ve been experiencing during the past few years and especially in the last 24 months. With that said, we continue to research new materials and expand our knowledge of shaft performance and will be adding to our product line soon. Our next product launch will be a comprehensive line of SteelFiber hybrid shafts. We have been getting several hybrid shafts in play each week out on tour and it’s time to share those designs with the golfing public.

ZK: Thanks for your time, Chris.

    My professional club maker, a Top 100 Guy, had no problems dialing in the correct flex and swing weight in my iron sets with Aerotech Steelfibers. I guess club making is an art… experimentation, talent and skill.

    After playing with an Aerotech rep by chance at Semiahmoo GC near Bellingham a couple of years ago, he encouraged me to experiment with their products through local fitters.

    Even though it is the iron shafts that tour players only seem to use, I actually ended up getting a stiff 70 gram SteelFiber in my three wood.

    The impact feels so stable and stays square.

    It’s money.

    Chris helped me select the SteelFiber’s I now have in my irons. Very approachable, answered all my questions, asked me a lot of questions, and was very helpful. I am very, very happy with these golf shafts.

    Im sure these are fine shafts, but they just didnt work for me. Couldnt get the feel down. I even had a GD top100 fitter work with me.

    Best of luck to them though!

    I have also had issues swingweighting a set of 125’s. In fact, they still sit unbuilt in the corner of my workshop. I just picked up tungeston tip weights (10g), so im hoping thats enough added weight to make them playable.. Perhaps we need to have a “Steelfiber LB” = low balance. I’d love to have a steelfiber shaft where the last inch of the tip section is just as solid steel rod with epoxy vents,
    I just hope when i finally get this issue worked out, that all the great things i hear about these shafts are true.

    I love these iron shafts, and they have saved my elbows and shoulders. Their old hybrid shafts work but I want slightly more kick. Looking forward to see what they have in the new versions.

    I love these shafts. Play them in titleist CBs. Dispersion is much better then with the DGs. First time I tried them I hit five 7 irons into a circle with a 10′ diameter (which is absurdly consistent for a 16 handicap)

      Also I wished he would have addressed the balance point issue a bit more. I added lead tape to my 3&4 irons because I couldn’t figure where the head was.

        Good point….so a tighter dispersion was your net gain? How can that be…when you compare them to steel?

          Lower torque maybe? I don’t know. But my accuracy has never been so good.

Today from the Forums: “New Axis 1 Tour-HM models at the 2020 Honda Classic”



Today from the Forums shines the spotlight on new Axis 1 Tour-HM models featured at this week’s Honda Classic. The flat-sticks have garnered lots of reaction from WRXers, with our members currently split on the unique designs.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • tiger99210: “I like them. Doesn’t look Odd at all.”
  • Barracuda: “I don’t get the hate on companies that are actually trying to do something better than what we have available. I don’t play axis1, but it was definitely on my shortlist, I ended up with a LAB putter. It does look funky; it also helps me score better than my stunning queen B6.”
  • Steel Dillo: “I’d be more interested if they were priced reasonably. Just don’t see what drives their cost up comparable to a fully milled specialty brand other than having Rose’s name on them. IMO, they should be in that $200-$250 range like their other putters.”
