Wall is too hard to drill

[flosswoss]

Hi. Am trying to put a knife rack on the wall but cannot drill deeper than 1cm as the wall is rock hard. I'm using an old one speed 450W drill with a regular masonry bit. I don't do enough diy to justify buying a new drill so would another bit be more suitable? Also I'm a bit confused about when to use the hammer function. Please help before I resort to no more nails!

hammer action is for precisely this occasion
check there is nothing electrical horizontally or vertically in line with the area you are drilling

also be aware off water and gas pipes

Thank you, I have used a detector to check for pipes and wires etc. Just bought a better bit so will have another go later. Fingers crossed!

Its not just the bit its the hammer action you need.

Hammer action and push hard, if that cannot go in you need an sds drill and bits, or else you are trying to hang shelves in a Tiger tank!

Thanks! Our friend who's an electrician came round to install a light fitting and in 20 seconds managed to drill the holes with that sort of drill - he says I can borrow it whenever but it's one for my Xmas list!
