Commentaire sur Rois 1 5:31

And they brought. From the mountains; an expression of uprooting.

Heavy stones. Heavy.

Hewn stone. Carved and chiseled. And if you ask, it has already been stated, “Neither hammer nor axe [nor any iron tool] was heard in the Beis Hamikdosh, during its construction.”²⁷Below 6:7. The explanation is, that no iron was heard in the Beis [Hamikdosh], while it was being built, but they would chisel on the outside, and bring in and build [it] inside. Thus is this expounded in the Maseches Sotah.²⁸See 48b.
