It's certainly cheap enough, but do you need something to hold onto to

And when it says impact rated for that second one, surely the impact is

It's only for the occasional job, including one coming up shortly where
I will be drilling a few holes into bricks.

Personally I prefer to have a chuck for versatility. Either of those in your

I have one from Aldidl - rough as hell from new, but stripped down and lubed
it's good.
Having a chuck is useful for drilling holes through joists etc.
