    Hi ther
    The local Kmart is selling 12v cordless drills for less than NZ$10 , about $7
    in real money.
    I was think of buying on just for the battery pack. Its less than the cost of
    2 good (Eveready) AA rechargeable batts.

    I know every drill will be different but generally....
    Will the battery pack just be nasty old nicads, or something better??
    What could I expect to see in the battery pack??. Just a bunch of AA batts
    joined together or something else ??

    Buy one and let everyone know.
     
  3. Yes they were selling them in Tas. about six months ago, battery packs are
    nicads, chargers are dumb, the drills are o.k. and will take standard 14
    volt packs.
    A mate of mine bought two for the motors, uses them for model yacht winches.
    I bought one because it was only $10 and apart from having to recharge the
    batteries fairly often, it is quite good ,useful to have lying around. Why
    not buy four of them and just use them up.
    Pius what more can you expect from a $10 drill. They were selling them for
    twenty last month.
     
  4. Almost certainly the poorest quality nicads available, and spot welded
    together. They won't be AA size.

  5. I bought one of these cheap drills less than a year ago. 3 weeks ago i
    replaced it with a $300 dewalt unit.

    If you are chasing just the batteries, your best of going and spending
    the money to buy some decent batteries from KMart
     
  6. So your dewalt one should last 30 years then huh? ;->

    Our $15 Bunnings drill is still going strong at work after several
    years.
    We got a cordless drill, half a dozen power boards, and a whole bunch
    of hand tools for under the $50 petty cash limit. Not the best quality
    for sure, but they work just fine, and the prices are amazing.

    I bought a Kmart 12v Arlec drill; it was ok for a year or two but the cheap
    charger stuffed the batteries because I left it on more than the 3 hours. I
    was able to fit a 12V transformer and rectifier in the battery compartment
    and now have a once cordless drill now with a cord. It beats chucking out
    the old unit. I now have a 14.4V Mactek from Bunnings....dearer but a much
    better chuck, proper charger with sensing and I expect better quality
    batteries from the outset.

  8. Time will tell, but at least i dont have to charge it every time i use
    it, and when it is charged i get more than 20 minutes use from it. And
    it only takes one hour to charge when i do need to charge it.
    How often does it get used?
    Power boards are another thing i refuse to buy cheap. A decent one
    will last, after a couple of dozen uses most cheap ones seem to refuse
    to hold onto a plug. I suppose thats OK if it sits behind your
    computer and never gets touched though.


    One thing i learned when i was a tradesmen is not to buy cheap tools.
    Whenever you need them they always fail on you.

    I think that's an entirely valid point, for a tradie. For Joe
    punter who stuffs around in the garage on weekends, A $300-$500
    makita just isn't justifiable (even though it is a fantastic
    bit of kit).

    I have a whole shed full of assorted $25-$50 el-cheapo power
    tools. I recognise that they're crap, and I understand that
    they'll die on me soon enough, but I only want them once or
    twice a year, and *need* them much less than that. I'd love
    to have all DeWalt and Makita kit (and I would have in a
    business situation), but the cheapies have their place.


    GB, I take issue with the "laser guided" circular saws from
    NRG ("Not Real Good"?) though. They're a lod of bollocks!

    In cordless drills, the best one I've had is an Aldi 18v job that was $50 -
    2 speed gearbox, mistreated thoroughly (including a few drops off a ladder
    onto concrete) and still performs. In the $300 range I hope you got one of
    the lithium-powered units.
     
  11. Well I am in that situation now. Let me give you another example:

    I bought a cheap $15 dollar sander to do a few parts on my boat. I had
    to keep placing the sandpaper back into the sander every couple of
    minutes. After 4-5 times, i went of and bought a (dewalt again) sander
    which has since done lots more. And this sander feels balanced and
    does not vibrate as much.

    My cheap drill that I bough, motor died when drilling through a 6mm
    piece of steel. My Bosch drill went through this with no problem and
    several times more, and is still going 5 years on.

    My 5 dollar cheap car battery charger overheated and died. I bought a
    $90 unit (made here in Aus) that does not even get warm when charging
    a dead flat battery.

    (i have more stories)


    Point is, if you are only planning on using it once, and only for a
    few minutes, then yes, the cheap tools are for you. If you intend to
    reuse it several times, you will get better value for money buying the
    low end tools from the big names.
     
  12. Not sure if its lithium. It came with 2 batteries, both last for a
    long time, in fact it has only been charged once since i bought it.
     
  13. Quite often, once a week on average I'd say.

    For home I bought a Ryobi cordless for about $50, this was the lowest
    cost one available before the $15 ones flooded the market a year or two
    back.
    It came with two NiCds and a crappy charger but it has been the most
    reliable drill I have ever owned. It has been dropped a few times from
    the top of a 7ft ladder onto concrete and has been filled with gyprock
    dust many times over.
    The stamina of the battery is quite good. I've used it to undrill and
    redo hundreds of screws in a day with one charge. Torque wise it's
    great, I've broken a few bits and locked up the drill many times, but
    it handles it without issue.

    Yes, the battery chargers are crap, if you leave them on you'll ruin
    the battery. Something to watch.
    We've had no problems with the $2.50 bunnings power boards. They get
    treated attrociously in both production and lab environments without
    issue.
    Interesting, all the professional contractors I see at work have the
    best tools money can buy, presumably because work was paying for them.
    But with the individual contractors (who work for themslves) I get for
    my home jobs, they all have the cheapest Ozito Bunnings tools. I asked
    why once, and one guy said they are much better value, he could buy ten
    Ozito's for the price of one top brand, and the top brands simply don't
    last ten times as long. That means more $$$ in his pocket.

    Not only that, but who is going to steal crap drills when many expensive
    European/Japanese brands are available on the same building site?

  15. In my experience the good tools outlast ten Ozito's.

    Take my fluke meter for example. The LCD cost $50 to replace. 1 out of
    10 drops will result in a cracked LCD. DSE $70 meter, 1 in 2 drops
    result in a fucked meter.

    The drill. Spending 8 hours waiting for a charge because your battery
    is fucked = 8 * $120 = $960. Driving to a site to find out your drill
    is fucked = Throw away call out charge, wasted driving time, ect ect..
    Pissing off the next customer because you are a day late...

    For me, every minute lost = money lost. For a small time contractor, i
    guess he places no value on lost time.

    You work it out.

    Irrelevant. If you are stupid enough to let your tools get stolen, and
    not have insurance if they are stolen, then bad luck 'ey.

    I have, thanks. You're getting very upset about this whole
    thing. Looks like your 'truth' is the only possible 'truth'.
    Very well, I'll stop "annoying the pig" now, I see no point
    in attempting to discuss your issue further.

  17. I am putting forward a practical viewpoint. Like i said, if you are
    only going to use the tool once or twice, or you dont mind waiting for
    a battery to charge etc. then go for it.

    Maybe but what about other factors? Theft, loss, etc. Everyone has different
    considerations for their particular need.
