I need to drill a couple of holes (cavity wall) from the loft gable
end to outside to pass cables through.

I decided it would be neater, easier and better to drill a 25mm hole,
slightly angled so it doesn't "rain in" and fit a piece a pvc tubing
(to prevent the cable chafing on the entry and exit) rather than drill
a number of small holes (one for each cable).

I have a set of long masonry bits that go up to 12mm so a can start
with those.

I thought it would be easy to find a long 25mm bit. It was. One such
beast is a Rawlplug 32-350 at 35mm x 300mm but I can't find any
website that specifies the shank diameter.

I could email/phone a supplier but I thought I'd just ask here on the
off chance one of you has such a drill and can tell me.

TIA

You need to move with the times and go to sds. I can't say I've seen
large diameter plain-shanked masonry bits for years.

There are multi-material bits (I use in my combi drill), but only up
to about 12mm

I wouldn't be surprised if a Chinese 1 metre 25 mm SDS bit and a basic drill
for maybe £50 was cheaper than a "western" plain drill on its own

I bought a screwfix 1m 25mm for £25 when they were doing them cheap -
fine in brickwork.

The tool stall on the local market usually has a few very large
drills at surprisingly low cost. I have so far resisted the urge
to get one "just in case". The ones which are simply large have
proved worth having.

Thanks. That's a good suggestion. I would imagine P&P on a 25mm x
300mm bit won't be cheap, so even if the cost locally is more, the
total cost might not be more.

Plenty (non SDS) for less than £20 but they don't say what the shank
diameter is.

It's unlikely I'll need to drill more than a couple of holes so was
trying to keep the cost to a minimum.

I appreciate SDS would be better/faster but the time it takes me to
drill them isn't a big issue.

Shank size will rarely be larger than 1/2" - since very few drills have
a chuck larger than 13mm.

You can also get core bits from about 25mm...

I hired an SDS and purchased an SDS bit from a local firm a few years ago.
Wasn't too expensive and the difference in time and effort was well worth
it. If you're drilling a core I believe you can hire those bits.

Umm... I did a series of 20mm Rawlbolt anchors in oldish concrete for
our pergola and damaged quite a nice Bosch 2 speed drill. The *hammer*
action will not now fully disengage and makes the drill useless for
drilling in steel.

I suspect the hammer cam has slid along the shaft:-(

My 20mm TC tipped drills are all 12mm shank.

CPC do a set of 3 (12,16,24mm) 1m long SDS bits which is often
on special offer for about £8. I've used them quite often
and they're still as good as new. Even if you don't want a long
hole, they can be handy just for reaching a higher location
without having to stand on something.

Handy for drilling behind skirtings or architraves as well since they
will flex enough to allow you to get a parallel hole even though the
drill must be by necessity slightly offset.

That's one website I never thought of looking on, which is a surprise
as they are local to me (about 20 miles).

I think my wallet is geting worried :-)

Talking of standing on something... I saw a pair of stilts at work
today. Not sure who was planning to use them but we do have people in
at the moment fitting false ceilings.

Found a picture of the exact ones at

I have the screwfix 12338 20mm (£5.89) but they also do a 25mm 11968 (£8.49).
The shank on the 20mm is 1/2" (nearly 13mm).
