When I used to make a feature of Helicoil TAP, the tap depth of (insert=1.5) is about 1.5times of  (insert=1.0). 

But now I use this SOlIDWORKS 2026(SP1.1), all helicoil depth is same. (Insert=1.0, 1.5, 2.0, 2.5, 3.0 are same tap depth feature).

So, I checked hole wizard setting and  the Helicoil Tap tables of all(Insert=1.0.~ Insert=3.0) are same data. 

I think solidworks muse be correct this problem. 

If it is not, Please let me know how to fix it.
