As per above. Use an SDS hammer drill. I struggled for years without and recently had to drill a number of holes for some CCTV cameras. The SDS drill goes through masonry like butter.

Interesting - checked out what SDS means, rechecked the Tesco site. The Black & Decker 860 (the 1st link - in my previous post) is an SDS machine, it is supplied by Tesco - so I can double-up my vouchers to get it!

Before wasting a ton of money on a new drill why don't you spend less than £10 and try some decent drill bits, it really doesn't matter how good your drill is if you are using rubbish drill bits it will never perform.

If you upgrade to SDS max or the like keep in mind you looking at £15+ per drill bit for anything decent.

SDS Max bits are expensive and more heavy duty. But SDS Plus is sufficient. The bits are not expensive either. I bought these:

An update. Visited Screwfix - got a set of Bosch multi construction drills, told these go through anything, these blue ones are better than the De Walt ones.


Anyway, the first hole wasn't too bad, went in using a '6' then a '7' to make it was wide enough for the plug. But the second one took an age, first go 1/4", after some several 'goes' gave up at an inch. Found it had worn away the shoulders of the drill!!
Still, at last finally the troughs are up - all I need to do now is fill them up with compost & plants - only thing with their height I'll need a ladder - doh.

I have a feeling an SDS would be too much on a concrete garage. Its a proper hammer drill, it wacks the wall with force where a normal drill has an eccentric cam and rattles a bit.
Any tough masonry drilling I find drilling a very small pilot hole first helps loads. I agree the dewalt extreme bits are excellent btw, but most branded new bits are ok. Its the multi bit cheap sets that are dire.

If I have a "hard" surface to drill, I start by using a tile drill, the type used on ceramic glazed tiles. The drills are small diameter and sharp pointed (unlike normal masonry drills). Once through the initial hard top surface I then use "ordinary" masonry drills.

Yes, and no - only ordinary!

You'll be kicking yourself if a rogue bit gets you, not worth chancing the sight in your eye. I got hit by a piece of masonry drilling with a hammer drill about a year ago, just below my eye. I was wearing the safety goggles but if I hadn't and the piece hit an inch further up....
