You don't need to be an 'investor' to invest in Singletrack: 6 days left: 95% of target - Find out more
Following on from my previous posts about which ground anchor's to use, I now need to go about fitting them. I need to drill some 16mm holes into solid concrete. My little DIY drill coughed spluttered and started shaking when asked to drill just the 12mm pilot hole.
So, can anyone recommend me a decent power drill with a hammer function that can drill 16mm holes into concrete? Would prefer to stay corded - no real need for cordless for the stuff I'll be doing.
EDIT: Goes without saying, the cheaper the better
TIA,
Kevin
hire one from HSS?

Budget for some SDS bits for use with the hammer action and get an SDS chuck adaptor for it if you want to use it on steel or wood with your regular HSS bits.
use a smaller pilot drill and work your way up to the 16mm and you should be fine.
16mm into concrete? Then you'll be needing an SDS - the Erbauer one above will be £40 well spent.
Buy some decent bits though and as Bear says, drill a 7 or 8mm hole to start with - use something as a guide to keep the drill square as you go down.
That Erdbauer looks perfect - seems to be out of stock everywhere though. Anyone know of any Screwfix's that have them in stock?
Only if you type my reply for me, I can't be bothered to do it myself.
I've got one of [url= http://www.screwfix.com/p/makita-hr3210c-2-4kg-sds-plus-drill-240v/51574 ]these[/url] that you'd be welcome to borrow.
You need to live in Mid Sussex though............
Don't pilot into concrete. When moving up a size it causes the bits to snag badly. 16 mm should be easily achieved even with a cheapy like the erbaur. Or go hire say a hilti sds plus drill and watch it eat the concrete!!
Without doubt the erbauer one will be fine for the odd job, and when it breaks screwfix will replace it.
but that might be a bit clumbersome for more general work. [url= http://www.toolstop.co.uk/bosch-gbh-2-28-dfv-2kg-sds-rotary-hammer-drill-with-quick-change-chuck-in-l-boxx-240v-p16274 ]bosch GBH2-28[/url] ftw. Mine has taken abuse on a complete house renovation, it astounds me every time.
But buy some decent bits. Cheap ones are almost single use. So you keep buying them.
Used to use HILTI TE10's, bombproof. I'll be ordering a TE1 for corded duties.
A mate had one of these we used on the barn build.

Damn near broke my wrist using a 30mm auger bit into a 200 year old elm beam 🙂
Hilti, you gets what's you pays for

whirling round in cartoon mode
you wouldnt believe how close to the truth that is! 🙂
😆
One imagines the Hilti might be a bit on the pricy side for the OP.
jathink? 😉
this is the one I actually have

Pretty knackered now. The rubber housing is fractured nearly all the way round. The chuck is getting stiff and the fancy blue light was broken on it's first outing. But ive treated it with such utter contempt and as little more than a breaker much the time. Still pleased with it for £60 including a handful of bits and chuck adaptor.
Yep, as much as I'd love to have a really good quality drill, I doubt I could really justify the expense for drilling 8 holes. I'm sure it would be a good investment, but can't really justify it at the moment.
In general, fancy lights on power tools don't last that long. I was giving someone a hand for a few days this week and he has a flipping huge Makita sliding mitre saw with a brand new blade. Suffering severe saw envy 😳
I got a cheapie Performance Power SDS jobber from B&Q when I needed to drill some holes in concrete -- it was nearly as cheap to buy as hiring one from HSS, so if it exploded after two days I'd still have been quids in. It didn't and thus remains a handy thing to have standing by 😉
I wouldn't bother with any of the B&Q own label kit. We bought their cheapy SDS+, and the chuck wasn't central, so the drill bit drew little circles. As the idea is that the bit repeatedly hammers the same spot, this meant that a) drilling a hole took far longer than it should, and b) getting a hole the size you wanted almost impossible.
We exchanged the drill, and the replacement was the same - chuck was skew wift. We then asked to check replacement for the replacement, and that was the same.
We then got them to agree to give us the next line up in the range. And they were all the same. By this point we'd wasted the best part of the afternoon on B&Q tat, and had checked most of their stock of own label SDS+ drills.
Then we went to Wickes, got one of their own label drills (re-branded Draper) and it was dearer, but spot on. Not as good as a Hilti, but orders of magnitude better than the B&Q gear.
Think of it this way - a Hilti is 203mm rotors with Saint calipers, the Wickes drill is a good set of V-brakes, and the B&Q drill was like a set of badly set up plastic cantis on a 20 year old Apollo.
