The Ryobi 2kg (£80 ish) seems to be selling well in my local Champions so presumably it must have some credentials as a "trade" tool. But you just don't know these days. Champions need to sell something not available elsewhere in the area, and Ryobi need a retail outlet. Quality is probably the last consideration.
The power input to a drill certainly does give some idea about likely performance. Are you saying it does not?
The senile one is saying just that. Sad we all know.
It gives some idea, but that's all. With an SDS you're interested in the maximum impact energy. Or with any power tool, the *output* in watts. A proper spec will provide this.
A cheap tool is likely to have an inefficient motor and drivetrain, so just comparing power input between makes tells little.
But then Drivel thinks boilers can be more than 100% efficient so the concept escapes him.
Strange given the way you quote boiler efficiencies from 55% to over 100% rather than their input power.
What a prat.
It gives a reasonable idea, IMO - above, someone wrote that it gives "no clue about performance" - an 800W machine is likely to have more oomph than a 600W one.
Yes, my £25 Aldi one is rated 900W, with an impact energy of 4J.
It does tell you something, see above.
I don't care what Drivel thinks, but I don't like all this stupid Drivel-bashing that generates about 30% of newsgroup traffic. It's probably helping and thrilling him enormously, and ought to stop.
What a sad bastard. Poor sod. Condensing efficiencies go up to 109%. That is the scale they use.
This is case of lack of parental discipline as a child. Spare the rod.....and now you know the result.
No it is not stange. It is senile babble.
The more they come the harder I knock em down. Chris, you have to recognise that Plowman is nut. Once you realise that it is easier. He just keeps coming back for more, when any sane person would have stopped it years ago. He is one of the ng nutters. There are about 6 of them who are just plane nuts.
A slight u-turn but we get the drift :-) I've used a 9 volt cordless that would take the head off a screw
Who's U-turn? Not mine, was it Drivel's?
And? One very commonly finds 12v motors giving well over 6HP...
As opposed to juvenile prating? Somebody, somewhere, please change your password and do not write it on a post-it which you then stick to your monitor. Further to that, stop your eight-year-old's pocket money for a month.

Nope. I always get it right. It was Richard Cranium.
But the trade still buy it. I know many tradesmen who use Ryobi and have done for the past 2 to 3 years and have had no problems and are well satisfied.
Randolph, do you go boozing with Richard Cranium?
It might or might not. A decent SDS drill could have a power consumption of say 900 watts but a power output of 550 watts or so. The rest goes in noise and heat.
That's the important figure. But if you do some checking you'll find 900 watt input SDS drills that manage 5J plus.
It tells you how much electricity it uses, that's all, as required by law. So not really too much to worry about on a mains tool which is used for short periods. But a power in against power out is pretty important with cordless stuff.
Then the killfile is your friend. It's a newsgroup and not owned by you, me, Drivel or anyone else. So if certain posters annoy you it's up to you to filter them.
Richard, I'm sure you are on many. You are a senile pest that is for sure, on of the resident nutballs.
*But it is likely to*. If you can't even see that, then I give up.
Chris, please give up, as the man is a waste of space.
Sorry, if you think that's an important piece of information, then you really do not understand at all. What if I tell you of a 900W SDS drill that gives an impact energy of 8 1/2J, or one that gives 10J? A drill that takes 1300W and gives an impact energy of 25J? A 900W SDS drill that gives 3.5J? A 900W drill that gives 3.8J impact energy? As a test question, which one of the above costs the best part of £600?
