This is an incredibly useful tool, and I've found the selection of attachments which accompanies it to be quite good. I bought this to use on a boat and I've found a million things to repair I didn't know needed a Dremel tool! It cuts and grinds stainless steel bolts more easily than anything I've seen, never mind bronze, fiberglass, wood, etc.

The battery, though, is what makes it both unique and frustrating. Of course being able to use the tool unfettered by a cord is great, and it does recharge reasonably quickly in about three hours. On the other hand, the motor is not as powerful as the corded variety, and the speed is not continuously variable. I haven't yet found either of these to be a problem. But you cannot get a half-hour of use out of a fully-charged battery. Fifteen minutes is more like it. This is plenty of time to practice home dentistry skills on the dog if you are so inclined, but it means that unless you have a battalion of extra batteries at $26 a pop you will not be able to grind out all the grout in your bathroom, cut more than ten ceramic tiles, or buzz off more than a few square inches of rust from your car from a single charge. If you are buying the tool for those sorts of projects you need the corded flavor.

I have a line powered Dremel but I most often grab for this rechargeable unit because its easier to handle without the cord. It is great for tight spots in the car. I recently upgraded the intercooler piping in my car and needed to enlarge a 2" hole to 3" diameter. I just used the cordless Dremel to make numerous radial cuts and bent the "tabs" back. I would have gone nuts trying to cut that out with a hack saw or file! I always use it at the full 15 krpm speed and don't miss a variable control at all.

My friend lost his special "antitheft" key wrench for his license plate mounting bolts. I just used a cut-off wheel to make two cross cuts in the (round) bolt heads, and unscrewed it with a Phillips head screwdriver. Without a Dremel, it would have been tough.

The battery life is short, but I always have an extra charged battery ready. If I'm working with it alot, I just rotate the batteries through the separate wall mounted recharger.

It can also be used as a printed circuit drill or for other small precise drilling. Much easier to handle than a typical hand drill for light work.

It does kick up some metal bits so use eye protection!

I'm not what you would call a handy sort of fellow; a few years ago, my greatest handyman-type success was the successful changing of a light bulb. Five years ago, I had never even heard of Dremel; now, I wonder how and why anyone goes through life without a handy-dandy Dremel tool. A few years ago, I got it in my head that I wanted to build my own working versions of Tom Servo, Crow T. Robot, and Gypsy of Mystery Science Theater 3000 fame. Such a project involves some tool-oriented activity, so for the first time in my life I found myself looking at tools. Since I know nothing about tools, I went about my business trying to look like I knew what I was looking for. I think every man responds to the siren call of the hardware department at some point in his life, but not until I found myself looking at a selection of Dremel products did I feel a strange lump of excitement in the pit of my stomach; tool anxiety had suddenly turned into tool excitement, and I gleefully returned home with this Dremel Multipro Cordless kit - feeling quite manly, I might add.

Exactly what does this thing do, you ask? Dude, what doesn't it do? It slices, it dices - no, wait, that's not right. This Dremel tool carves, it grinds, it polishes, it sands, it cuts, it brushes, it drills, it does darn near everything. It comes with 50 accessories in the form of abrasive wheels, drill bits, wire brushes, polishers, engraving cutters, router bits, and cutting wheels. I, being born with a passive tool-user gene, can't really tell what each accessory piece does just by looking at it, but I'm sure most halfway intelligent people can. I have fun just trying to figure it all out. What I needed at the time I bought my Dremel kit was a little sander tool, and even I could recognize the accessories made for that purpose. I soon had my proto-Tom Servo head free of jagged edges and was ready to delve further into my little project; this was just the first of many little Dremel success stories in my suddenly tool-enabled household.

The tool itself is a portable two-speed unit that comes with its own battery and charger. Whenever you get through using it, just plug it back up to let it recharge, and it's ready to go the next time you need it. It is light-weight and allows for different grips, helping to ensure you can pretty much reach whatever little space you need to get to with it. This model has two speeds - 7500 and 15000 rpm. That's pretty darn fast, and that high speed combined with the unit's low torque makes life pretty simple for you - the tool does all the work for you, making this the perfect tool for weaklings such as myself. Now, if you're into some heavy-duty work, the Dremel tool may not meet all of your needs, but for many odd jobs around the house and all manner of hobby activities, a portable Dremel tool is the way to go.

I must say that the documentation that comes with the kit is quite impressive and does actually describe each accessory and its proper uses. Of course, my being a man, I don't think it's legal for me to read a manual, so I just get by on instinct and luck. The kit also comes with a colorful little book telling you all sorts of jobs you can do with your new Dremel tool - if you have a significant other, you might want to keep this kind of information away from her/him. Even if you do get stuck doing odd jobs your better half would never have conceived of without the insight of the Dremel documentation, at least you can be comforted by the fact that you will have a lot of fun playing with your new essential Dremel tool.

If you were frustrated with the power or endurance of the Dremel Cordless Pet Nail Grooming Rotary Tool-- (http://www.amazon.com/Dremel-761-03-Cordless-Grooming-Rotary/dp/B0000C6DZ2/ref=sr_1_2/002-2958210-2482411?ie=UTF8&s=hi&qid=1188235101&sr=8-2),

I've got the tool for you. This one uses a rechargeable battery and has excellent power. I've got a 100 lb. German Shepherd with huge nails and he does NOT like to get his nails trimmed. This tool did the job fast, no worries about cutting too deep with a clipper, and the battery charge lasts a long time.

One caution is that the rotary sander will generate a fair amount of heat, so don't work one nail too long or it will get uncomfortable for the dog. It's worth the extra money for this tool and you don't have to feel bad about running through all those AA's.

This tool could be great, but has a MAJOR flaw. The battery pack is designed such that it pops out of the tool with the least bit of pressure. The battery pack is actually part of the handle, so you can't avoid touching it when working w/ the tool. I found it very difficult to work with the tool for more than a few seconds before it shut down because the battery popped loose. I resorted to duct taping the battery in place. Eventually I got tired of this & I heated up the case with a butane lighter and bent the sidewalls inward to more firmly grip the battery. With this modification, (or with duct tape) the tool works fine. But you shouldn't have to resort to this sort of jury rigging. If the product people at Dremel had actually used this tool, they could have identified and cured this problem.

I have 3 Dremels now: a regular AC variable speed model, a cordless that runs at 5 and 10 thousand rpm, and this one. The convenience of the cordless models causes the AC model to lay on the shelf most of the time. I advise anyone purchasing a Dremel to also buy the 4486 MultiPro Chuck. If you change tools frequently the chuck is really essential, and I have no idea how I could use my 1/32nd and smaller drills with the collets available. It seems to me that much of the criticism I read in the other reviews of this product are from people expecting the Dremel to be a substitute for an electric drill-- In that regard I agree that it isn't one. However, for someone doing highly detailed miniature work, the Dremel is an essential tool, and the two cordless models are the best of the lot. I have had no trouble with the battery coming loose on either cordless model, and I am quite satisfied with how long the charge will drive the machine, and the relatively short time needed to recharge them.

I bought this in a bit of an emergency situation and it helped greatly. We needed a tool that could do some "hand milling", shaping, and filing of some small plastic parts to finish a mechanical engineering project for one of my classes. It worked really well on the plastic but when we tried using it to smooth some metal threaded rods, we chewed through a few files before the job was finished. I'm glad I bought this Dremel though because I'm sure I will be able to find some use for it in the future. The fact that this unit is cordless is also a huge help even though the batter only lasts about 20-30 minutes when used.

Bought it to trim the three labrador's toenails (or claws, as it's been a while...). They don't love it, but they put up with it much better than the clippers. We're trimming once a week, and no more worry about bloody toenails.

I've had this thing for over a year and I must say it is a good item, although there are a few annoying bits to this tool.

The battery pack itself is a pain, it keeps falling out, which may be a flaw in the design of the casing itself. The recharge-able pack works only 10 minutes after a full charge, which is understandle, being cordless and all (which isn't really an issue, just a reminder to those who are considering this item).

This tool is a great starter kit for a hobbyist or a crafts-person. It's not an advanced or professional kit, but thats ok, afterall, it was never meant to be in that market.

All in all, I'd say it's a great tool.

This tool is small, quiet, and easy to hold, even for a woman. It doesnt kick back when it turns on or while you're working with it. When you turn it off, it stops its own rotation immediately instead of spinning to a stop. I got it for my boyfriend for Christmas.

Comes in a nice, compact black case that snaps shut, and even holds the manuals. One small complaint is that the attachments are left to float freely around the box. This can be corrected by using ziplock bags to hold them.

Easy to charge because the bottom of the tool pops off and fits into the charger, so the whole tool doesnt have to hang from your wall.

A couple of notes that would have helped me, so may help you- I thought this tool could be used as an electric screwdriver, but it can not. It spins too fast.

Also, be aware when looking at the Dremel tools that some are corded. I almost ordered a corded one, but decided on this one because of the convenience of use. Corded ones give you more power per price. I think this is the most powerful cordless model offered by Dremel.
