There are large numbers of Chinese-origin SDS drills coming into 'DIY Sheds' at ludicrously low prices. The largest outlet is own-branding such a drill at about 80 quid, with 3-year warranty. So far, so good!
But the small print of the warranty specifically EXCLUDES 'trade, professional or hire use'. How exquisitely dumb! For a start, an 850 Watt SDS drill is hardly a DIY must-have for the xmas stocking. And if DIY stores deliberately exclude tradesmen from their clientbase by this sort of thing, what's the point of B&Q 'trade credit cards' etc.?
I'd be the first to agree that these drills are complete crepe. That's the whole point. no-one will nick them and they're so cheap that if one breaks you chuck it away and get a new one. Problem is - it stuffs up the job while you get the new one. I'd MUCH rather 'DIY Sheds' paid more attention to quality and less to their lawyers who draft the warranties! Also, I bet many Chinese exporters are pretty miffed that ALL their products get the bad reputation created by the cheap 'crepe'.
You can buy SDS chiseling drills the shape of the £350 Bosch Multi-Drill for £30 upwards. I met a double glazing installer using two. They usually last him about a year, but are usually dropped or stolen before they wear out.
I think they're perfect for DIY xmas stockings!
Eumig (if I recall correctly), made cine projectors.
Aldi are selling Eumig 9.6 volt rechargeable cordless air pump. It looks like a cordless drill. Has a pressure guage at the rear to measure pressure. Cost about £15.00.
Certainly a lot easier than than pumping the twin cylinder body builder.
I've always used the electric air pump thingy that Antares sell for about £30.00. Get the extension hose with it too and the only sweat you work up when re-pressurising is carrying the thing in from the van. It feels soooo decadent to just flick the switch and watch that pressure gauge rise :-)
Big and clumsy to use (and store) though. That Eumig device sounds like another big improvement - provided it lasts more than five minutes.
