Is one Dremel as good as any other?

Am looking for a Dremel on ebay. Seen five model numbers with varying voltages. Will the cheaper, lower voltage ones be OK? I'm not sure what I'll use it for, just random things that pop up I suppose. I do have to cut a notch in a rear Mudhugger I bought (a flange for a cable on the seat stay is in the way). It's thick plastic. I want the option of doing a bit of metal cutting as well though...you never know. Just wondering if the cheaper ones like the 7750 (4.8v) are a bit weedy...

Ouch, just seen the price, the little ones are good for little jobs, some of the guys at work use them on verry small delicate jobs but for for a more general purpose tool they have the 10volt ones (untill the batterys flat & the mains one comes out )
There's plenty of non dremel grinders out there if you didn't want to spend 100's.
For a few years in my shed I had a cheap (Maplins) solar pannel topping up an old car battery powering a no name 12 volt grinder that would usually be powered from a 12v plug top adaptor.

The battery ones are pretty useless, though I haven't tried any of the very latest ones. Whatever one you get, look for 30,000 rpm. There's a Bosch one for £60. See if you can find similar but cheaper:

the one i have is 33000rpm no load speed and 36 quid so extra 20 gets you some extra bits on top.

even the new batt ones are crap so i have been told just dont last long enough grinding and cutting under load.

.. the battery ones might serve if you are planning a life of crime cutting through locks! They are pretty much precision tools so suitable for fine work . Their typical power is 100w so how long will those li ion types last? 10 minutes under load?

I've used a mains-powered one from Aldi for years and it cost £14 at the time. It lasted many, many years and was used for many jobs....cutting s/s was one of them and it served to repair a huge number of bikes.

A colleague of mine brought me back a mains powered dremel from the states some 45 years ago. I have replaced the brushes once and it still works. I was so impressed that I bought a few with stands for use with practical classes drilling PCBs in electronic workshop practice.. eventually we replaced them with more conventional mini press drills with more stable chucks. The hand held dremels are fine for grinding and polishing. They also have cutting disks, which work very well but are terribly brittle. Even a little hand shaking and they will snap... I would use them for cutting bolts to size.

Having read this I decided the cordless one would probably suffice. It goes up to 28000rpm. Got it from Argos for £85. The £68 Screwfix one is not currently available anywhere for some reason and the £80 Homebase one wasn't in stock here. The Bosch thing d8veh mentioned is without batt or charger.

Hmmm! I think I would have rather spent the money on a petrol generator. I use mine in the shed frequently. It's easier than bringing out the extension lead. Aldi often sell generators for about £60. One time, they reduced the price right down to £40.

You`re not wrong there! When you get one snap at 20k rpm, fly past your ear and embed itself in the shed wall you`ll reach for the hacksaw next time.

Petrol's expensive, smelly and polluting and generators are noisy.

As lm twice the age of most of my workmates, I cringe every time one of them uses powered tools with a total disregard for there eyes dispite having safety glasses available. I have pointed out the potential dangers so many times I can't remember....................sory this is turning into a rant, just remember your safety glasses
