I think the thousand suns line is hyperbole, but that's just me. It could be argued that the air around the hammer was heating up due to the friction of swinging the hammer (like when spacecraft burn up in re-entry). Maybe that is why Thor survived the hit himself. But I agree that it could possibly one shot an average showing herald level being. Definitely not a high end high herald level being though. Characters in classic comics grossly fluctuated inconsistently in power, even skyfathers.
Why? I mean, that's probably not the exact amount of joules of energy that the hammer had but he knew that this was Surtur that he was facing after all and I'd wager it would have been very dangerous even for him.
Thor survived the attack but he was taken out. And this arc was the definition of a high end herald level being in terms of Thor (And Loki). Not to mention that Thor has a very powerful connection with Mjolnir.
Surtur was easily a Galactic level being and this was a high end stakes game (If Surtur lit the flame, he'd burn creation) with Thor really kicking it up a notch. Not sure what fluctuation you're talking about. Although I'd like to see an example of this grossly fluctuating Surtur.
Fun fact: Although in the scans I posted, that was supposedly Thor's most powerful blow, he goes on to charge up his hammer even FURTHER:
Thor doesn't just hold back massively. He has like layers.
In this story, Surtur destroyed a Galaxy while forging the Twilight Sword. With it, his power increased greatly, and it became even greater the closer he drew to the eternal flame.
