A couple of things to address. The DBM finish is extremely durable but does change the amount a carbon steel head can be bent. In the case of the PTM with the DBM finish, we do not recommend bending. I personally have been able to bend some 1 degree, but it is not consistent, so we longer recommend bending them. So, we will work with you and replace the heads or refund the purchase. You will need to tell customer service that you discussed with me and they should take care of it. The Satin Chrome version is fine and you can bend those, no problem. Also, as an alternative, the DBM forged head (MA0225) can be bent if you want the dark finish. We can also check to see if we have a set of the PTM in the dark finish that have the lie numbers you want, without bending. Not sure we will be that lucky, but we can try. You may ask why the DBM iron can be and the PTM with the DBM finish can’t. We have found that different carbon steels react differently to the DBM process. The PTM is 8620 carbon steel, where the DBM is 1035 carbon steel. We continue to research and work on the process to try to understand why this is the case, but for now there is a difference.
I do want to comment on a couple of things with regards to bending irons. First, Loft and Lie machines are not the accurate way to measure a club. They tell you how much you are bending, but they base lie readings on groove alignment, not actual center of sole alignment. So you should always measure the number on a golf club gauge to know the actual lie reading. As a side note, I did check stock and did not find one head at 66.5 degrees. All were within tolerance. I was a little concerned about that number. Secondly, it is vitally important to use the proper type of bending bar when bending. Too many times I see a short hosel bending bar being used on standard length hosels, which can increase the chance of damaging the iron.
Really sorry for what you experienced. We should have done a better job of listing these as not bendable. If you do this kind of thing long enough, these kind of things can happen. I can’t stress enough that the only way to get accurate lie readings before you bend is to measure the clubs in a golf club gauge. No bending machine on the market will give absolute accurate lie readings unless the grooves and the ground line when touching the sole in the soles center are absolutely parallel to each other. Not many are. Loft readings should be accurate in a bending machine. Lie readings, it all depends on the groove line and it’s relationship to the center of the sole.
