Sds max

[Millsy 82]

Right then I am pricing a few jobs which will involve drilling through nice thick granite walls!

Now I have long ads drill bits that are long enough but after my last run in with these walls which pretty much killed me and my drill (4 1/2 hours to get 3 28mm through the wall) I have decided that I need to get a half decent sds max and drill bits including txt core bit for upto 5" (although I think knocking the wall down and rebuilding it would be a better option)

So what drills are half decent? I don't want to break the bank so Hilti are out of the question.

Also I am after long drill bits upto 30mm plus in diameter. I have seen them somewhere but can't remember where.

Not another one subbying at Hatton Garden?

Yeah, as Ray quoted, you would be better off hiring a core set with drill from tool hire depot.

I wish I was clever enough lol.

The amount of granite cottages down here it's not worth hiring one every time. Just to run a 22mm gas pipe through a house took 4 hours with a sds plus 30mm drill bit then a core bit and core drill as I can't get a long 30mm in sds+.

I just wouldn't bother with SDS on granite mate even small diameter as you've discovered.

Get a core drill and some decent diamond core bits, if it's just for smallish diameter you could get away with using your existing SDS+ with a core bit to SDS adaptor with hammer OFF.

Funny you bring this up as I found this earlier in the week:

First one I've found. SDS Max gets expensive, I priced a DeWalt one up recently at about £600 + VAT. 3 year warranty though on dewalt.

I saw a Bosch for about £400 the other day the only thing is I bought a cheap Bosch 24v and it was terrible.

I need to get one hiring isn't an option really as loads of the jobs down here involve granite cottages. I was hoping including bits to get around £1000-£1200 in total.

There's a Dewalt agent on flea bay selling refurbs for about 60% retail, I have a 7kg 1200w sds max which does everything I want and this 9kg 1500w is about as powerful as you can get bit only one year guarantee.

I used to have the predecessor to this model (HR5001C) until it was knicked and it was an absolute monster, rarely in 240v though.

Why are you discounting core drill Millsy, that'd be ideal for your application?
