There's no comparison. Many times I had a customer watching as I
prepared to drill through a wall using a decent SDS. [Fairly brief
noise from drilling] "Err... is that it?" "Yes!" "Bugger me!" They've
often tried to drill little holes for shelves etc so are expecting a
mammoth struggle for me to drill right through the wall.

Although you mention 'cheap'. I wouldn't know, but a good quality mains
SDS is only about ?120 anyway. Non-SDS drills are ****e. In fact they
won't even drill through ****e, once it's been left out in the sun.

You can even get a Bosch or DeWalt for ?99.99. Obviously not the tops of
their respective ranges. And if willing to go to Titan or Erbauer, drop
twenty.

I paid about ?25 for a green Bosch some 12 years ago. I think the, now
defunct, DIY store had mispriced it.

My Makita was very close to £100 - and I see it is now quite a bit more, £150 or more. That is in about three years.



And the spec is the same?

Chances are it will be fine.

That's the sort of task more likely to knacker you IME!

There is a huge variation in concrete, and hence how hard it is to drill
- especially with a normal percussion drill. If you are lucky and the
floor is relatively weak then the percussion drill will make a hole it
in. (drilling down is somewhat harder since you can't clear the dust as
easily). However you may take a fair amount of time per hole. If the
concrete is hard, then you may find it very difficult and time consuming
per hole. (and good quality drill bit like a Bosch multi material one
will help)

*any* SDS drill is massively better at drilling holes in hard stuff.

Of course, but the heffalump in the room is the fact that you also have
to buy all new drill bits too, because you can't use your ordinary
ones !

I have a conventional chuck which fits into my SDS drill. So, I can use
ordinary bits without having to bring asecond drill with me.


But not in hammer mode !, especially if you were drilling concrete.

My Titan cost £69.99 a fortnight ago.

That is hardly the heffalump in the room, perhaps a small mouse!

Drill bits are cheap, and you can buy a set of the common sizes for
relatively little. Then just get whichever long/large bits you need to
use as and when.

Fully endorse the SDS comments, but,
Still sounds like a lot of work. Thought about hiring a Spit/Hilti gun?


Yup, that's actually a very good point

Think laterally a bit - don't even bother trying to screw down the
timber, nail it to the floor instead!

(You can also get long arm attachment for the nail guns to allow them to
be used at a distance (e.g. from a standing position into a floor or
into a ceiling etc))

Pretty much - there were two or three nearly identical models when I bought mine. I'd have to check to be 100% but things like wattage, looks, brief read of description, all are the same.
