Drill question

need a little physics/electrician helping here! I have been offered three drills that my parents have accumulated and don't need, but ive only got space for one of them in my bag. unfortunatly only one of the drills has a charger, i think that dtrill is 9.8V, but the other two are 18v and 24v. obviously i would rather take the 24v, it is much better quality too, but will the charger still charge the battery? or do i have to settle for the shit one?

get a new charger and take the 24v.

chargers easy to get?

What make are they? Some chargers from the same company will charge a range of batteries.

Also it depends on what you want to use the drill for as the 24v maybe heavy and the 18v maybe be a drill/hammer drill.

If you know the make of the drills check ebay for chargers.

i think they are all generic, one is called powermaster or something, the other is powermatic, one of them is woolworths haha

If it's NiMH according to this http://en.wikipedia.org/wiki/Nickel-metal_hydride_battery#Charging it depends on the method of charging the charger uses. If it's a trickle charge then yes if it's delta V then I guess no as the cells will have to be groped in series to achieve 24 volts so the 9 volts will not be enough (read the wiki link), if it is delta T then I guess yes. Multi grove will probably know more.

but the batteries still fit in the charger and have the lgiht on as chargin, i just didnt know wethere they would charge to the full 24V

What does the label on the charger state? Voltage for example and what make are the drills?

but the batteries still fit in the charger and have the lgiht on as chargin, i just didnt know wethere they would charge to the full 24V

The best thing to do is leave it for a few hours then stick a volt meter on it and see what it's pumping out.

Is it a NiCM or NiMH battery? As I siad I'm only interpreting wikipeidia and what I said only applied to NiMH anyway.

the charger is for the Powerbase, and i think it says it goes up to 12V
ive had a closer look and the 24V is Power Devil and it is a hammer drill so i wanna take that one, but a little look at someone with a similar problem on a DIY forum seemed to suggest the only option is to buy a whole new drill. crud

ebay didnt seem to come up with anythign for that specific drill. just gonna take the qweaker one for now, with its charger, as it is mainly only for polo mallets anyway, and if i find a charger for the 24V then illpick it up some point i guess. cheers for the help guys!

What do people think of this:

At the moment I am using my mums 20 year old Bosch drill, but that can't be used as a screwdriver, no clutch and all that.

I want to get a new one, Bosch are generally good quality, and this looks good as a screwdriver, and for most drilling jobs (and looks like a good deal).

I've been told I can't really use that for masonry, is that true? I was told I would need a mains powered drill/driver, or just a normal drill with hammer function, but the costs of good news ones of those is too much anyway, so if I need that I'll just hire one, or borrow my mums.

buy it, you can never have enough power tools.

hi john,

i don't think the psr18 is very good, cheap undoubtedly, just not very good. Suggest spending twice that on a lower end professional model erbauer / makita

You may well be right, but could you tell me why you don't think it's good? Obviously you get what you pay for, but for the 3-4 times a year I'll use it, it would be hard to justify spending much more. I much prefer the Bosch professional range to the DIY range, but the price difference is huge.

Boch stuff is good quality DIY level stuff IME, for three or four times a year it will be fine. Makita is excellent as suggested by rive gauche and professional quality, and hence professional price!

Just listen to your drill, if it's getting hot, the motor or the bit, stop or you will burn out the motor or soften the bit depending on which is hot. Use oil on the bit when drilling metal, regularly pull the drill out of wood to clear swarf when drilling wood, don't just push all the way though a thick peace, these type of things will all reduce the load on the drill and help keep the strain on the drill lower. Use of good quality bits is more important for an occasional use drill.

it'll be alright for gerneral drilling / screwdriving tasks, but it won't even touch masonary. You need a hammer function + way more power for that. I've recently been buying tools from Buck and Ryan in Holborn. They sell reconditioned Dewalt, it has a 28 money back guarantee if you don't like it and a full years warranty. I got a Dewalt cordless driver for £45. Bargainlicious. The guys in there know there shizzle too.

The price of NiMH powered cordless drills is coming down as the Li is battery is replacing them.If you want a bargain on a decent cordless hammer drill/driver keep an eye on the Screwfix website and B & Q. I picked up a DeWalt DC725KB 18V Combi Drill from B & Q with two rechargable batteries for £85 (reduced from £199.99). The batteries are 1.3NiMH though so they will only run for a hour or so before recharging. But you just charge up the other whilst you work. A great investment though.

You may well be right, but could you tell me why you don't think it's good?

ok, there's not enough metal around the gearbox, chuck, collet and battery compartment, and the levers look and feel plasticky (they're in b&q if you want to fiddle with one). however for enthusiast use it's well reviewed on amazon.

if you're set on bosch then the Gxx range is better if you can afford it

boring.....

it's true, forums are great places to indulge the inner trainspotter :D

Innit Murts... what's wrong with a hammer and chisel?!

I've been drilling holes in walls today to fit rawplugs and you definitely need the hammer function for masonry. I always borrow someones but it's a Bosch and it wasn't expensive but seems fairly good quality, never had a problem with it.

Finally something that I really know about.

Green bosch are ok but week. Same with entry level drills by any of the big guys.

Go to screwfix as they always have offers on. Site are makita built but unbranded and good for the dosh. If you want to drill into walls you want a "combi" drill as tat will have a hammer action switch.

I'll post some links.
