First, I've not put in 10 inch lags. Do they have hex heads,
so you can turn them with a socket wrench?

I'd be thinking pilot holes, with a corded drill. Remember
to pull out the drill often, and clear the "flutes" or
grooves in the drill bit.

And then a shot of lubricant like aerosol white lithium.

Corded impact wrench from Harbor Freight to turn the bolts.

I am trying to choose an impact drill (driver) that can
install 10 inch
Spax lag screws in pressure treated timbers. Although I
would prefer a
corded model, I find very few corded models on the market.
( Am I being too
quick to want to shy away from battery operated models ?)

Has anyone here actually used an impact driver to install 10
inch lag screws
and if so, which driver did you use for the job ?

Thank you very much !!
