Wanted long Masonry drill

Help please I`ve exhausted all the usual outlets and without success cannot locate

a long masonry drill. I only require it for two holes for tv cable to go from my garage built alongside Cortijo into kitchen adjoining.

My 46 cm drill bit will not go through far enough. I am not sure how deep the wall is but would think 50 or 60 cm would do it.

I have been using an 8 mm wide drill but width not really a problem as holes would be hidden.

I cannot locate a Ferreteria which supplies anything that long and do not know of a hire shop in the Baza area.

So I`m looking to beg borrow or buy such a drill piece if any kind soul can assist.

Hope you can help.

I used my drill hammer for the first 49 cm , then i have take a steel pipe diameter 20 mm and a large forehammer . and hit it trough the 1.5 meter wall of the cave . It worked

The hire shop is on the left after the Baza hospital turning..you will see it with the machinery outside..

Thank you all for your replies
I'll check the hire shop this week Thanks. .

All sorted
could not obtain drill so resulted to brute force with a length
of slim steel bar and got through. .
measured the distance after the event and drill was only once inch short in the end.
Thanks to you both
