yes I understand what you are saying, but cordless drills lack power for heavy drilling -so if you want to use a cordless you will need to be patient.
fence posts are pretty damn hard -its a big ask to drill into them at all tbh
I remember those days.

I'm using decent mid-class drill bits (metabo 626706000) which is about a tenner on amazon and has decent 4.5 rating and lots of reviews ~250, so it's likely boils down to:
[QUOTE="^woody^, post: 4666949, member: 37821"you need a different drill that will drill the hole in 15 seconds not 15 minutes. An SDS.
[/QUOTE] Any recommendations for suitable cordless SDS drill under 150-200 quid including >3Ah battery and charger?

I don't mind being patient at all and I am patient. I'm happy to spend 15-20 min per hole as I only drill like a dozen a year or less, so time isn't a big concern. But recharging and thus killing the battery every ~15 mins IS a concern, hence I find the new Dewalt drill with 1.3Ah battery useless for this.
I've managed to drill 10 holes into 4 different posts with a cordless Workzone hammer drill (14.4V, 1500mAh) and that lasts for at least 30-40 mins on full charge thus I can drill ~two holes per charge. That's OK. I thought Dewalt combi would be faster but apparently not + battery discharges very quickly. So far waste of money.
Yes, I'm serious. You've bought the bottom of the range drill and battery from dewalt. Can't imagine it's designed for drilling into concrete for more than a few holes at a time to put up a hanging basket or something.
Wrong tool for the job, sorry. You would have been better with a cheapo corded drill for what you're doing.
What the heck are you drilling that takes 10 minutes anyway? Have you got it on hammer drill mode?
Are you boring 25mm holes or something silly?
You'll burn the thing out pretty darn quick running it continuously like that

indeed - a budget mains SDS is £50

I have that one, because I don't need anything better and I don't drill that many holes. It goes through brick like butter, and when I have needed to do concrete far faster than my cordless one, now I wouldn't even bother trying.indeed - a budget mains SDS is £50

It makes DIY much less effort, even given the need to use an extension lead.
did you see my post ??
I missed this post. You really are using the wrong tool for the job!
For what it's worth, I have the DC 996 dewalt and 5 amp batteries. I've put a 12mm hole through a reinforced concrete post and it takes about 20-30 seconds, using a 12mm masonry drill bit, on order to put a bolt through.
However if I've got multiple masonry things to drill, I get the titan corded sds drill out.
Think the OP is now on their way back to B&Q to demand to speak to a manager to complain about the 'poor' performance 
Then home via Aldi to stock up on whatever workzone tools are in the middle isle this week!

the difference between cordless hammer action and mains SDS action really is chalk and cheese

I would say 'black and white', but is that allowed?

No only 6 mil hole - 3-4 then 6, see my post above
