long drill bits

[Jennie]

Hi all,
I need to buy some long drill bits so I can install an outside tap. I've seen these online:
Hilka 3 pce SDS Long Drill Bits 450mm: Amazon.co.uk: DIY & Tools
Would they do the job? I figured 450mm is fairly long, but not too long. I thought I'd drill a smaller pilot hole, then follow through with the 24mm bit (and use 22mm pipe sleeving for the 15mm pipe carrying the water).
Regarding sleeving, is copper pipe OK? I've heard somewhere that for load-bearing walls, stronger pipes are recommended.
Also, I'll be insulating any exposed copper piping on the outside. But what about the bit running through the sleeving - surely that would be at risk of freezing in winter?
Thanks for your advice,
Jennie

Most cavity walls are little more than 300mm wide, so 450mm will be good handy size. 24mm bit is plenty. Insulating the pipe will not protect it much from freezing, especially if on an exposed wall.
Never seen a wall that could collapse around a 24mm hole!
Sleeve the pipe tight with a copper or plastic pipe or just tape with insulating tape to protect from corrosion and avoid copper pipe plus fittings outside.
Remember the frost will freeze the tap but then travel inwards and potentially burst the pipe. Best you can do is insulate the tap outside in winter & fit an isolating valve inside.

For sleeping a pipe carrying water....use plastic electrical conduit. A 2 meter length is about a quid in screwfix

Or pinch a bit from a Spark! :smile:
Conduit makes great sleeving & it also does to temporary protect copper pipes coming out of floors & walls after first fix.

Also, 22mm Hep pipe or other makes makes a good sleeve for 15mm.

if its for a few jobs only they should be fine assuming you have an sds drill. If you plan on using them alot then pay alittle more and go for better quality bits.

They are £8.89 in TS , but as AWheating says, they don't really last long, it's not that they wear out fast, it is because the tips either snap off, or just plain ole fall out

Try and remember to isolate water and drain the pipework to the garden tap when it starts to get colder regards Turnpin:smile5:

I've got those, different 'cheap' brand but almost certainly out of the same factory. Every so often Lidl have 1000mm long ones of the same version which i've got too. I've drilled loads of holes with them and as long as you have a decent corded SDS they'll eat anything.

As for fitting the tap jennie, alway pipe down to it where poss, as that way in winter you can shut iso inside and open tap outside there by draining the tap and pipe, ergo no water no freezing.

one down side to cheaper sds drill bit as with all drill bits and blades is you make the drill/tool work harder, not a problem with a cheap drill but if you have spent good money on quality tool you will want it to last as long as possilbe.

I suppose its like having an expensive camera but a cheap lense.

Better to work the other way and have the tool be the cheaper unit than what you use in it
