Yup. I can't see the benefit of the added complication and weight of
hammer action on a cordless, given that most common bricks etc can be
drilled OK with a decent bit and no hammer action.

Well im slightly surprised you have gone along with this one.

Masonry drills tips are ground to a chisel edge and are designed to be used
in a hammer action, this angle means they don't cut. Ever tried drilling
into wood with one ?
So the only why you make a hole in masonry with one is by abrasive friction,
which will
a) blunt your drill
or b) as the carbide tip is brazed onto a softer shank, melt the tip off.

This is one for the misuse of tools, bad working practice, and a qualifying
point in the.
