Club Building 101: Shaft tip diameters; sanding .370″ to taper
Every club head has a certain tip diameter designed for a specific shaft. As a club builder, it’s my job to know which shafts work in which heads, and also when to use certain tools — like a shim or a reamer — to get the optimum shaft into the club head to create the best fit for the player.
This video explains those processes, along with both hard and soft stepping. I also give you the definitive answer for sanding a graphite shaft to taper.

Then and now: Comparing Rory McIlroy’s current setup to his record-breaking 2019 Canadian Open victory
In Rory McIlroy’s first appearance at the 2019 RBC Canadian Open, he crushed the record books to earn his 16th PGA Tour title in dominating fashion, winning by seven shots over Shane Lowry and Webb Simpson.
McIlroy’s score of 22-under-par 258 is the lowest 72-hole score to date at the Canadian Open, and his closing 61 is also the best final-round score in the history of one of golf’s oldest tournaments. Finally, with his win in 2019, McIlroy became only the sixth player to win the career Triple Crown, adding to his victories at the U.S. Open in 2011 and The Open Championship in 2014, joining Tommy Armour, Walter Hagen, Arnold Palmer, Lee Trevino and Tiger Woods in a coveted list.
So, with that, why not compare his current setup to the clubs he used to break all the records?
Driver
2019: TaylorMade M5 (9 degrees), Shaft: Mitsubishi Tensei CK Pro White 70 TX
2026: TaylorMade Qi4D (9 degrees @8), Shaft: Fujikura Ventus Black 7X (45 5/8 inches)
McIroy led the Tour in Strokes Gained: Off-the-Tee in 2019; he’s doing the same in 2026. Between now and then, McIlroy has switched from the Mitsubishi Tensei CK Pro White 70 TX (a shaft with slightly more feeling in the tip) to the original Fujikura Ventus Black 7X, having just made the change to the heavier version from playing the 60X.
What’s interesting about McIlroy’s 2019 setup is that the weighting on his driver is actually set in the high-draw setting, using the T-Track weighting system, whereas in the Qi4D, he’s currently using a heavily rear-weighted setup. (Two 13-gram weights in the rear and only two 4-gram front weights.)
The TaylorMade M5 driver he played in during his Canadian Open win was the company’s first head that they claimed to design to initially exceed the USGA’s COR limit, and then injected with tuning resin to bring it back in bounds.
Fairway woods
2019: TaylorMade M6 3-wood (15 degrees), Shaft: Mitsubishi Tensei CK Pro White 80 TX; TaylorMade M5 5-wood (19 degrees), Shaft: Mitsubishi Tensei CK Pro White 90 TX
2026: TaylorMade Qi4D 3-wood (15 degrees), Shaft: Fujikura Ventus Black 8X; TaylorMade Qi4D 5-wood (18 degrees), Shaft: Fujikura Ventus Black 9X
The TaylorMade M6 fairway wood that McIlroy was using during the 2019 season is still in the bag of some of the best golfers on Tour in 2026. Just check out Justin Rose’s winning setup from the Farmers Insurance Open earlier this year. This year, though, McIlroy has still been searching for his top-end-of-the-bag setup, having played both the new Qi4D and the Qi10, which he won the Masters with.
The same shaft swap can be seen in the fairway woods as the driver, along with slightly less loft on the 5-wood.
Irons
2019: TaylorMade P750 (4) Buy here, TaylorMade P730 (5-9), Shafts: Project X 7.0
2026: TaylorMade P760 (4), TaylorMade Rors Proto (5-9), Shafts: Project X 7.0
The biggest difference between McIlroy’s custom set and the stock P730s is the groove design. While the P730s were constructed with 14 MX-9 grooves on their milled faces, McIlroy’s proto heads instead use the higher-spinning, 16-groove layout of the TW2 grooves. Other big differences between the sets are that McIlroy’s 7- and 8-irons have thinner toplines, are 1 degree stronger in loft, and are 1/4 inch longer than the original P730 builds.
With McIlroy’s 4-iron, the switch from P750 to P760 sees a transition to a two-piece construction with Speed Foam in it, which allows McIlroy to launch the ball slightly higher, with more workability.
Wedges
2019: TaylorMade Milled Grind (48-09SB), TaylorMade MG Hi-Toe (52-09SB, 56-09SB, 60-LB09), Shafts: Project X Rifle 6.5
2026: TaylorMade MG5 (46-09SB, 50-09SB, 54-11SB, 60-08LB @61), Shafts: Project X 6.5 (46-54), Project X 6.5 Wedge (60)
Between 2019 and 2026, McIlroy’s focus on his short game has been much more apparent. It was the reason why he switched back to the TP5 golf ball, to help with launch, spin and control with his wedges leading up to his career Grand Slam victory in 2025. The most apparent changes to McIlroy’s wedge setup are his lofts and bounce. He’s slowly delofted his pitching to a sand wedge, but has increased the loft on the lob wedge, bending his current 60-degree to 61. With that, adding more loft to his lob wedge also slightly increases the bounce and leading-edge sit point, so, as a result, he plays a lower-bounce lob wedge compared to 2019. The MG5 wedges are also softer than the first Milled Grind option from 2019. McIlroy also no longer plays the full-face grooves found on the Hi-Toe.
Putter
2019: TaylorMade Spider X
2026: TaylorMade Spider Tour X
Notice anything similar. Yes, the copper finish on Rory McIlroy’s Spider X putter in 2019 is a slightly more reflective finish than the recently released torched PVD finish. McIlroy was using the True Path alignment system, but now uses only a single white sightline.
Ball
2019: 2019 TaylorMade TP5 (#22)
2026: 2025 TaylorMade TP5 (RORS)
As mentioned above, McIlroy had transitioned from the TP5 to TP5x golf ball since his victory in Canada in 2019, but now is black with the same style of golf ball as his victory at Hamilton Golf & Country Club.
Grips
2019: Golf Pride Tour Velvet Cord
2026: Golf Pride MCC
Interesting, McIlroy actually used Golf Pride’s Tour Velvet Cord grips during his victory in 2019 (it was during a 2+ year switch to the corded TV) as opposed to his usual MCC grips, which he has played for most of his career.

Or,,,, you can bore out your Irons to 370, much easier and the fit will be better. This guy is a Master Club Maker? Advocating this sanding stuff is BS. It ain”t easy to get it correct, and Taper tips are each make for a number. The design of the shaft is totally different.

To bore out the hosel of a taper tip iron head requires precision drill press , a couple of different size drill bits and reamer for accuracy and consistency throughout a set and even then, chances are some fits will be loose , very loose and others tight. A taper fit is always the same, if the tapers are accurately machined.

Correct Tony Dyck – the difference between parallel and taper is merely 0.015 of an inch. Anyone attempting this would logically use a good caliper gauge to the appropriate diameter and depth of the receiving hosel.

Shanking this video. Doesn’t explain enough and it leaves a lot of people still confused. You need more diagrams and actual footage of the parts you are describing and the work it takes to make, say, that 370 fit into the 355. And say that yes, it “fits” but it’ll never play the same or feel the same as a real taper tip that has a long taper section at the bottom 3 inches than the same 370 thickness of that parallel shaft.

Likely should have proofed this episode before airing it. I get it that it’s not easy, but the one that stands out is that you are only sanding off .015″ of the tip diameter and not .15″ (and only .0075″ off the radius).

Thank you for addressing issues that are not often discussed.
Suggest that the advantage of taper tip iron shafts is that properly machined tapered tip shafts inserted in tapered bore clubheads, are much more precise and consistent through a set of irons than parallel tip shafts inserted into clubheads machined for parallel tip shafts.This is basic knowledge in the machining business.
It is much more expensive as you point out to machine, sort and match taper tip shafts to clubheads; however if machined properly the taper fit will always ensure the shaft is perfectly centered within the hosel, close to “interference fit” throughout the set and there will not be looseness found in parallel tip irons.
IMO it is one of the main reasons golfers say that they notice a difference between forged clubs compared to cast iron heads. The difference in feel IMO, is due to more precise fit of shaft and clubhead with taper tip shafts in taper tip heads, which is common with more expensive forged irons. Cheaper cast iron heads more commonly will have parallel tip shafts in parallel heads. Its cheaper for the manufacturer.
So although mfg may say it is ok to grind or sand parallel tip graphite shafts to suit tapered tip iron heads, I suggest the precision inherent with irons with taper tip shafts precisely machined in the factory, may be lost when taper is done ad hoc for each shaft. If the irons are expensive forged, IMO dont compromise the feel for relatively small shaft cost savings.
