Large hand-held drill for 1 metre thick stone wall

[OwlHoot]

Any serious DIYers here?

I need a large hand held drill with a diamond core drill attachment, to drill a small (about an inch or 2.5 cm) hole through a roughly metre thick stone wall.

Searching, I can see only carpy little Black and Decker drills or, at the opposite extreme, huge diesel-powered drills on trailers, no doubt costing thousands.

What do bank robbers use to drill through thick concrete walls? That's the kind of thing I'm looking for, although I'm not planning to drill into a bank vault!

TIA

A meter? Yikes.

The answer to your question is they use a rig and a core drill like the Hilti DD350 (as made famous in the Hatton Park job)

That said, you probably don't need a core drill for your diameter but that's pretty deep.

Domestically you can do most things with an SDS with a clutch. It'd certainly do the diameter and you can get long SDS bits:

Forgot to add, don't start with a 20-30mm bit. I'd start with something like an 8mm, and maybe even step up again to 14 or so. And remember to go at an angle upwards to the inside to stop water.

And for my money you won't get better value than the Makita 2630. Superb kit if you don't mind it being wired

Great, very many thanks for your prompt reply vwdan!

Now I wonder if one can buy walkie talkies that work through a metre of stone. (Only joking )

This. I borrowed a friends Hilti clutch drill to get through a double skin dense block wall to two and half feet or so with a shorter drill than in the links but went through like butter and going up drill sizes was much easier.

Also measure the depth of the wall and put some tape on the drill an inch or so less. You want to go through the last bit on normal drill else you bash through with the hammer and create a large crater at the other side. If it doesn't matter then, well, forget that bit.

It's OK, I've found a suitable drill bit:

Use a small archaeologist's pick because the prison officers might get suspicious of a drill.

As VWD has said, get an SDS Plus. If you don’t want to go to the expense of a Hilti, or you don’t have many holes to drill:

The guys who did the Hatton Park job got their drill from the Toolstation in Twickenham. My local!

If you are doing it yourself then as per the replies above, alternatively google your local area for diamond drillers (trade name) & get someone in
