Am I being dim?

I've got an 18 v Makita and I'd never expect it to get through a cavity wall with a 16 mm hole.
Not this side of Christmas anyway.

 

To be honest without an sds drill even a good combi can struggle depending on the brick you have and if your cavity wall is breeze or thermally, with that drill stage your drilling, start with 7mm drill bit then send the 10mm down it you'll need a long bit, then get a 12 and 16 mm hss masonry drill bit and drill down your 10mm hole again staging it up. This is a long winded way but without an sds drill it's probably the only way to get that drill to do the job.

 

I've emailed a local tool hire place to see what they reccomend, what do you think? http://www.itstools.co.uk/

 

I'm a dewalt man myself 18v xr sds with a couple 5amp batteries had it coring 2 inch holes as long as you do it right 18v can do most jobs

 

Which is why I said go down the hire shop.
You dont e mail the hire shop, you go there, get what you need, use it, and take it back.
Job done.

 

I like the SDS battery operated ive used various brands nice bit of kit, I've never owned one a bit pricey for me, I use a bosch SDS 110V with chisel action it does what I need it to do.

 

True , I install a fair few Armandii, I charge £50 supply and fit in front of the sink window that's the soldered type not the cheap ones with hosepipe connections, its not really a lot of money and could save you flooding your home out.

 

I was quoted double that and I was supplying the pipe and tap etc.

not planning a trip to the Isle of Wight any time soon?

 

I wish i was , they only take a steady hour to do that's with a chat and a cuppa half hour if you was in a rush, the bits cost around £20 I am happy enough with £30 PH .

 

Btw if you've bought this type 8 times out of 10 it will leak and flood you out make sure the water turns off before doing anything .

 

@IceColdRum Do any of your neighbours/friends have an SDS drill you could borrow?
I fitted one of those ten years ago and it's still fine. I did have the plumbers here installing a new bathroom at the time so I asked them to drill a hole in the wall (no charge) but the rest of it I did myself just following the instructions on the packet. See us women can do DIY too

 

One of these?

Dreadful things (sorry). Life expectancy of twelve and a half months. I've fitted a few over the years and always done it properly but last time I bought one of those DIY kits. The break-in connection had a dribble and in the end I just replaced it with a capillary fitting and a reducer taking the opportunity to fit a shut off valve as well. Good job that I did because as soon as it was out of warranty the tap started leaking.
As far as the hole goes the quality of drill is less important than the quality of the drill bit. And it seems obvious but if you're putting it by the kitchen sink double check that it will not emerge in line with the sink pipework for ease of working.
