Dremel MultiPro Cordless 7700-02 20,000 RPM Two-Speed 7.2V Rotary Tool System w/50 Accessories

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!


An incredibly useful tool that even I can use without mishap   May 13, 2004

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.


Know your purpose--not for doggy toes   November 13, 2004

I bought this tool from another company as a dog nail grinder. However, there are other Dremels better suited for this purpose. Also the product specs on Amazon are not always correct--double check first on the Dremel web site. This tool is currently spec'ed for 10K and 20K rpm. For puppy dogs slower is better as the friction is less and the nail does not get hot as quickly. Best tool would be something around 5K rpm. I think that's the slowest they sell. Some reviewers complained about the 8000-01 Lithium-Ion Cordless so maybe the 7800-02 9.6V Cordless MultiPro is a good bet, though I have seen good reviews on the 750-02 MINIMITE Cordless Tool however it's slow speed is 6500. BTW, specs for the 761-01 Pet Nail Grooming Kit are not online at Dremel so I can't confirm if the Amazon specs are correct, you need the owner's manual to do that. Thanks! and Good Luck!!
