Yes indeed, you need it especially to start with to keep the hole on the
right place at least, so they should be able to manage that OK. However I've
never taken a hammer drill to bits.

My DeWalt SDS drill turns but doesnt hammer.
Someone siad there's a spring inside which I may have broken by pushing

Hpw easy are these things to repair,

You shouldn't have to push at all, thats the whole point of SDS.

Hammering doesn't engage until it's pushed. Basic physics says it could
hardly be otherwise.
