I am looking at buying a new cordless drill, i have seen a b&d 18v with a 1.5Ah battery and a Bosch 24v with 1.3Ah battery. Q? what is the Ah? and how does it effect performance of the battery?
 
Amp Hours. The higher the Ah, the more power the battery holds.

An ideal 24v tool has 2Ah or thereabouts. 1.3Ah is going to work fine, but it will need recharging more frequently and won't have the same grunt as a higher capacity battery.

a bit simplistic i know but think of volts as your car
engine and the amphours as the petrol tank the bigger
the engine the more the power the bigger the fuel tank
the longer you keep going

Trician,
How powerful are modern cordless hammer drills? Are they suitable for drilling through a brick with a 15mm bit, or only for drilling small holes for rawlplugs? Are they a suitable substitute for a corded drill (with the exception of SDS)?
I'm only used to the small budget 12V non-hammer drills!
Cheers
Jon
 
To put things in to perspective jonny,I to have the 18V DeWalt the same as Trician (how we doing TT?) and it is as he says a brilliant piece of kit,all metal gearing,replaceable brushes blah blah.

I also have a DeWalt 110V corded percussion,which is now up for SALE.Its only been used once.

The cordless has replaced it.

Hi SF,

Jon,
15mm masonary bit in brickwork? Take it steady on the slowest speed and she'll get you thru'.
Might pay you to have a spare fully-charged battery standing by for afterwards but unless you hit blue engineering bricks you shouldn't have a problem.

My only negative comment about the dewalt 18V model, is that the speed control is not precise enough and I find it too heavy for screwdriving. Other than this, its a belting peice of kit :)
 
Cheers Trician,
£260 in Screwfix...may invest in one in the future. Wasted so much money buying cheap £50 ones in the past...
Jon.
 
Don't mess about here - get a dewalt 18V hammer drill
- superb piece of kit and well worth the money.

if i could just add to the comments, im going to buy myself the 18v De-Walt combi drill in the next 2 weeks, it sounds like you 2 are happy with ures, and after using a 14,4 + 24v SDS both dewalt, i would say 14.4 appears to run out to quikly, and the 24v SDS was just way OTT for screwing up surface fixings etc, so i feel 18V is ideal size.

also it's pretty nice becase you can use the de walt radio and charge ur batteies in them 2. the radio owns.

for any 1 thinking of buying them soon, i would strongly suggest www.toolstation.com they sell all the same de walt drills but there in competion with screwfix it would seem, and the prices are quite a bit lower.

have fun drillin all :)
 
RE: Toolstation - are their quoted prices inc VAT?
Don't foget delivery either. S/F used to deliver FREE if the order value was over a certain amount.

I am looking at buying a new cordless drill

I guess it all depends on what you're using it for and how often. I bought a DeWalt 14volt hammer drill since at the time DW only sold a 12 or 14volt right angle drill (and this is one useful piece of kit for working in floorspaces !) They now sell an 18 volt one, so must be even better.

I'd recommend the Bosch 'green' range for light/DIY use or the Bosch Blue or DeWalt for trade use. The DW 14volt hammerdrill gets used for most drilling, screwdriving, but I've also got a corded SDS for drilling holes larger than Rawlplug sizes.

I'd get batteries of at least 1.7Ah if you're doing much more than putting up a shelf kinda work. Get at least two batteries and make sure they charge in an hour or less. Finally, (sorry Screwfix) I've found www.diytools.com (aka Powertek) to be very well priced and CSMabrasives (www.sanding.net) to be the most helpful power tool suppliers. Oh yeah, don't buy anything by Ferm, unless you intend to throw it away before too long - really are Christmas Cracker quality I'm afraid (had a sander that just sort of self-destructed after a couple of hours use).
 
There IS only one make of power tools and that's DeWalt period-fullstop-end. By the way try eBay a second hand DeWalt is worth 20 new Bosch or any other make. So far I have acquired a lot off eBay, DeWalt's, a brand new Robin Loop Tester with DLoc (for £250 with guaratee and certificate - I think they are about £450 list).
 
If you want a proper professional cordless tool, Hilti is the tool
