Driver shaft snapping in the same place

[idontnoh]

Wondering if anyone could give me an answer as to why my driver shafts keep snapping near the adapter? I've had two shafts -- an Accra (Mizuno tip) and a Hzrdus (TEE tip) -- fail at the tip, near the adapter over the last 6 months. Pictures below. Given each manufacturer's reputations, I have to believe this is more user error than it is faulty manufacturing so can someone please tell me what's wrong with my swing that this keeps on happening?

Usually caused by heel strikes or undue stress on the head from loading and unloading the bag.

Hm, interesting, thanks. Neither case applied here as the Accra was at the driving range and the Hzrdus was on the course this morning.

Have they been removed from previous tips/clubs?

 

Overheating will breakdown the composite and weaken it..

 

I've had this happen to a shaft that was previously removed from another club..

Heel strikes meaning hitting the ball off the heel of the driver near the shaft adapter.

I had this happen to a shaft I changed the adaptor on.  Obviously I used too much heat...

Yeah, definitely not that either. My miss is high toe so it’s not because I hit it near the adapter. I almost never hit shots off the heel. Thanks for the suggestions!

Hzrdus was stock from TEE. Accra was a brand new shaft and the Mizuno adapter was professionally installed by a top 100 fitter in Northern Virginia. 
 

still at a loss for how this has happened twice...

On the pics you provided it appears the lumen of the shaft is filled with epoxy well past the top of the adapter.  If this is the case then  that could certainly be a cause of shaft failure at that point.

Never had one break there. I did have on snap at the handle between my hands when I started my down swing the other day. Strangest thing ever. Thought I got too close to an overhanging branch or something. 

[mgoblue83]

Soo.. how often do you hit off the heel and/or drop kick it off the ground/mat? 

 

 

Is this you?

Interesting. I never noticed the epoxy but both were professionally done (one was stock), so I don’t know if that played a factor.

Honestly, never drop kick it off the mat/ground and almost never hit it off the heel as my miss is a high toe. Thanks for the input and entertaining video!

At one time some graphite shaft manufacturer's said their warranty was voided when hitting off driving range mats.

Do you ever slam your driver head into the ground?

Never. I'm not an angry golfer and don't flail around after a bad shot.

What's your SS? What weight and flex were these shafts? Do you go after it hard with a late release, or are you smooth in tempo/transition?

SS averages between 103-107, depending on the day, but nothing world beating. I have what a fitter described as a "late, violent release" and generally go after it.

And these were all X shafts in the 60 g range. 

[RogerinNewZealand]

Then suggest 70+ gram stronger shaft for your transition.And with a Firm Tip that is built for your transition.

I thought these were all stiff tipped shafts but I never thought to go heavier. Thanks for the suggestion and time to go to BST...

[RogerinNewZealand]

Think of rear axles...8 inch or 9 inch then Dana 60...your only at 8 inch with 60 grams.In 1995 i played with a big fella,steel shafted driver, huge build and swing.Steel is Option 4....👍

Sorry, can't help you on why these shafts have snapped, however "The Club Pro" guy is hilarious. Never heard of him, just watched about ten of his videos, best golf instruction and advice on youtube. As far as shafts, do you ever lean over to pick up your tee, or even when putting peg in the ground and lean on club for support? 

[Tufph]

Had this happen to my best friend. Was the weirdest thing, 3 hole tee shot, ball goes flying and the club head is hanging on a few threads. Called OEM and they changed it for him.

We wrote it off to as too much heat.

 

Goto velocore - strong tip. Lol

[bluedot]

My son did this twice, both times at the range.  I was told by a really good club guy that this is common for high swing speed players because of the high rubber tees at ranges, which tends to move the strike more toward the heel of the club.

Stop hitting the club on the heel and this will stop.

If what you just stated is accurate, I would think lines of golfers are forming, returning broken clubs. Tons of us have both toe and heel hits. Manufacturers are building these clubs for the average player, even advertising that toe and heel hits will not affect distance or accuracy. They are designed knowing where the average player hits it and it's not middle of the clubface.

I fit people everyday, all day. The easiest way to break a shaft off at the hosel is repeated heel shots. If you break 2 in a row, there is a good chance it is the operator, not the implement.

Heel strikes. All day, every day.

thanks but heel strikes are not the problem at all. As stated earlier, my miss is high toe and I rarely hit towards the heel. Thankfully, TEE’s legendary warranty and customer service came through and they replaced the shaft in 3 business days.

If heel strikes aren't the problem, then it's something else, not a defective shaft.
