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

• Very handy, but not for every application

  
  By A343AFAT1JZQTY on 2000-07-01
  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.
  
  

• Extremely useful gadget

  
  By A1RX06VI29OO9M on 2001-10-09
  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

  
  By A3KF4IP2MUS8QQ on 2004-05-13
  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.
  
  

• Dremel 7700 MultiPro has one major flaw

  
  By on 2000-06-30
  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.
  
  

• Pretty good so far, though I haven't used it that much...

  
  By A17JG1S28DV34R on 2000-04-11
  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.
  
  
• Know your purpose--not for doggy toes
  By A17KHC2602ZHSY on 2004-11-13
  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!!
  
  
• Very handy tool
  By A1CQRJFY5EEMDZ on 2002-05-02
  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.
  
  
• Useful for small jobs
  By A2ENEGKNVXBANF on 2002-08-28
  Overall a good useful tool for light duty use only. Battery life is very short and the cutting wheels are delicate. I've pretty much destroyed all my wheels and stones putting the dremel to tasks which it obviously can't handle. The case is rugged and holds lots of bits and attachments.

  I plan to purchase a corded dremel for those more ambitious jobs.
  
  

• not bad
  By on 2002-05-29
  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.
  
  

• The right tool for pet grooming
  By A1BWIVTQSQCZM0 on 2007-08-27
  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.
  
  
• Nice set, wrong tool shape
  By A3VLVKS3CC82V8 on 2007-10-19
  The form, fit and function of the hand-held tool is poor, but the tool set attachments are great. Even the little bag is a nice touch.
  
  After many decades, I bought my first Dremel hand-held tool. However, if the battery was turned 180 degrees and the French curves on shallower side were made into a flat surface, parallel to the rotating axis, then it would be extremely useful for cutting balsa wood to make models. It would also be able to sand all surfaces with precision. I don't believe there is one Dremel table that would have this stand-alone-flat-surface capability to handle any work size.
  
  I would guess that Dremel Marketing dictates to Dremel Engineering, just like marketing at Microsoft must dictate tons of application bells and whistles, whose bugs are rarely fixed (even after 17 years of re-packaging MS Office applications)...marketing seems to drive almost all companies.
  
  I registered my Dremel product and signed up for the forum. But I don't think Dremel wants to hear from folks with any suggestions. Of the 30-40 permissions, I only had the right to read, not to make replies. I guess the Dremel legal department reins in users with muzzles...no wonder there are very few postings.
  
  If you do register with Dremel, DO NOT check any boxes pertaining to your interests. If you do, you can count on a deludge of third-party emails, selling everything from travel deals to fake online degrees. It appears that Dremel sells your name to profit from you, while you are not permitted into the domain of a one-sided forum. I've spent way too much of my time unsubscribing and adding to this review (which you will not see as the most current review on Amazon).
  
  If "money is no object," then buy all the Dremel tools (shaper/router table, scroll saw, drilling station, etc.) that you need to do the job right (hand-held tools with French curves are how Marketing promotes sales of all other Dremel tools). Just don't expect the tool to be innovative in form or fit (I am impressed with 20k rpm, but speed falls off quickly as battery drains), and don't expect the battery to last more than 0.5 hours cutting very soft Balsa wood.
  
  Technical functionality is the very best of form, fit, and function. Aesthetic functionality is usually the application of misguided technical functionality dollars. We consumers will always buy what we need, regardless of bad press, but more product support, allowing us to provide critical feedback, would be a good thing for everyone...not using "buy what we need" as a marketing lever to sell us inferior products.
  
  According to the U.S. Department of Labor Health Hazards (OSHA)abrasive saw blades and disks:
  
  (Author, not OSHA, note: You should wear a protective mask when using Dremel abrasive disks or any abrasive saw blade. This may not mean that all abrasive disks are coated with Cobalt, but I don't know what substance, other than carborundum, could be coated on such blades. Even though you should wear a filter mask, it may not absorb Cobalt fumes).
  
  OSHA: "Health Hazards. Cobalt Dust Stellite tipped saw blades generate a fine dust containing cobalt when sharpened. Cobalt is a silvery, bluish-white, odorless, and magnetic metal (author, not OSHA, note: test yours abrasive disk...magnetic steel disks will be misleading...with a strong magnet). The fume and dust of cobalt metal is odorless and black. Without proper ventilation, cobalt overexposures are possible. Cobalt also is combustible and burns brilliantly (Author, not OSHA, note: Dremel disks do not burn when exposed to flame)in air at room temperature. Dusts of cobalt metal or cobalt compounds may form explosive mixtures in air.
  
  Inhalation of cobalt metal fume and dust may cause interstitial fibrosis, interstitial pneumonitis, myocardial and thyroid disorders, and sensitization of the respiratory tract and skin. Chronic cobalt poisoning may also produce polycythemia and hyperplasia of the bone marrow. Among 12 workers engaged in the manufacture or grinding of tungsten carbide tools (cobalt is used as a binder for tungsten carbide crystals), who developed interstitial lung disease, there were eight fatalities.
  
  The current Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) for cobalt metal, dust, and fume (as Co) is 0.1 milligram per cubic meter (mg/m(3)) of air as an 8-hour time-weighted average (TWA) concentration [29 CFR 1910.1000, Table Z-1].
  
  Signs and symptoms of exposure:
  
  Acute exposure: Acute exposure to cobalt metal, dust, and fume is characterized by irritation of the eyes and, to a lesser extent, irritation of the skin. In sensitized individuals, exposure causes an asthma-like attack, with wheezing, bronchospasm, and dyspnea Ingestion of cobalt may cause nausea, vomiting, diarrhea, and a sensation of hotness.
  
  Chronic exposure: Chronic exposure to cobalt metal, dust, or fume may cause respiratory or dermatologic signs and symptoms. Following skin sensitization, contact with cobalt causes eruptions of dermatitis in creases and on frictional surfaces of the arms, legs, and neck. Following sensitization of the respiratory system, cobalt exposure causes an obstructive lung disease with wheezing, cough, and shortness of breath. Chronic respiratory exposure results in reduced lung function, increased fibrotic changes on chest X-ray, production of scanty mucoid sputum, and shortness of breath. Chronic cobalt poisoning may cause polycythemia, hyperplasia of the bone marrow and thyroid gland, pericardial effusion, and damage to the alpha cells of the pancreas.
  
  Methods that are effective in controlling worker exposures to cobalt metal, dust, and fume, depending on the feasibility of implementation, are as follows:
  * Process enclosure,
  * Local exhaust ventilation,
  * General dilution ventilation, and
  * Personal protective equipment."
  
  Author, not OSHA, note: In terms of other brands of saw blades, you should not use abrasive blades...use something else (An Evolution Rage 2 Chop Saw is fantastic and patented technology...this is where I found out about the dangers of abrasive disks) . Abrasive blades can also explode in your face when over-heated.
  
  
• Unusual application?
  By on 2003-06-08
  I'm a woman with SERIOUS calluses on her heels. All the usual home care in the world won't keep them in check, and pedicures and visits to the podiatrist are expensive. After a podiatrist used a Dremel and an X-acto knife to reduce the calluses--that's how bad they are--I tried my husband's corded Dremel myself but found it was too easy to burn myself; the outside edge of your heel is not the easiest thing to get to, and the high speed burns instantly. I bought the cordless model and found it much easier to maneuver and less likely to burn at its slower speeds. Periodic use on my heels when they're dry, with more orthodox methods on them when they're wet, keeps them from splitting, shredding stockings and looking like rhinocerous hide. Plus it's handy for its more conventional uses, although not suited to the heavier work of the corded Dremel. If I lost it I'd buy another pronto.
  
  
• Almost Flawless
  By A3FJSYPSCWDZJH on 2003-12-28
  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.
  
  

• Cordless version has quirks - but does great job
  By on 2004-01-12
  Good: high speed+abrasive wheel cuts through ANYTHING, light durable feel when using, vast array of bits makes this a jack of all trades from cutting to polishing.

  Bad: battery pack does not last very long, On/Off Switch is not definite (safety concern?), needed to buy 2nd battery pack while working a a bathroom project

  This is NOT a drill. I see other reveiwers complain about this. If you want torque buy a light-dimming 12Amp Milwaukee Power Drill. The Dremel is an abrasive tool. If used intelligently it will do ALMOST anything you ask it to.
  
  

• Great golf club cleaner
  By on 2002-06-04
  I bought this tool exclusively for cleaning the heads of my golf clubs. I put in a brass bristle brush and clean the dirt out. Works great on golf shoes too.
  
  
• handy but be sure you know battery capacity
  By A9V2HY4C2EI5H on 2007-06-10
  This is a handy tool but the battery life is weak. For example, a battery on full charge will not last all the way through cutting a 2" x 4" hole in a metal downspout.
  
  If you decide you want this Dremel anyway, say because you value its small size, be sure to buy a spare battery.
  
  
• short lasting battery and no power at all
  By A33O2DDGCM9YCY on 2007-06-29
  Pros:
  -small and cheap
  Cons:
  -Long charge time required
  -Ni-Cd batteries inside can't provide enough power to the motor
  -motor is not nearly powerfull enough for anything harder than plastic or wood
  -fully charged batteries are running dry in 7-10 min of continuous work
  -switch design is VERY BAD. it's tended to turn itself ON from slightest touch - very dangerous if you have some cutting head installed at that time.
  
  CONCLUSION: don't buy it for your kids, and if you need to work with it for more than just 5 min - then take a corded version and look for more power too, because this obe sucks real bad
  
  
• A poor long term choice
  By A1RUN5ZMPH8I2D on 2007-07-03
  While the capabilities of all Dremel products are excellent, this suffers from poor battery life. Mine lasted less than 40 hours of use, and replacements are not available from retailers such as Lowes and Home Depot. With replacements batteries at Amazon for $20 or direct from the manufacturer at $25, unless you really, really need a cordless, spend the extra money up front and go for a 300 series. You will soon recoup the extra cost.
  
  
• Wimpy, Wimpy Wimpy!
  By A1912F7HH08UGT on 2002-04-10
  I got this thinking it would help out in basic home repair. I think it is more for the hobbiest. It wouldn't do even simple home repair work. Ended up returning it!
  
  
• Dog Toenail Trimmer!
  By A28HKB1UJBWSEA on 2008-06-12
  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.
  
  
• VERY Useful Project and Household Tool
  By AGFA0CXY1D27D on 2007-01-23
  This item would receive 5 stars, since its usefulness easily merits 5 stars, however there is a problem with the kit I bought. They do not come with the Dremel chuck that makes it convenient to change from one bit to another. The collet-nut system it comes with is time consuming and I don't like it. I had to purchase the chuck separately. The only other negative thing I can think of regarding it is that it should be less expensive to buy an additional rechargeable battery to go with it. Otherwise, this is a great tool and I would recommend it to anyone for crafts or around-the-house projects.
  
  
• dremel tool
  By AMLSD87Y2MQ9 on 2007-09-28
  I had owned a dremel tool for years but it is electric, meaning you have to drag the cord around your work. I found myself not using it very much because of the cord problem.
  
  This tool is battery powered and two speed. In addition, it is very light weight making it easy to navigate your work.
  
  I found my foot doctor using this product to trim down nails and remove dry and cracked heel skin with the sandpaper attachment, which is shipped with the product. I highly recommend this product.
  
  
• Good basic tool, but watch...
  By A16LSTTPWK117Y on 2007-12-30
  This is a great tool for anyone needing to drill, polish, cut, grind, etch, sand, screw, etc.... but not for big projects. If you have larger projects, consider purchasing a more powerful, corded Dremel. But for crafts and basic home repair, this product works great.
  The battery pack is easy to get on and off, and holds a charge well. (a back up battery is a good idea with ANY product!)
  The only thing I can really say I'd improve on, would be the on/off switch. I don't like that it goes High/Off/Low rather than Off/Low/High, for safety reasons. I have, on more than one occassion (while trying to switch tips) switched the unit on. There is no well defined seperation between the Lo/Off/Hi.
  Otherwise, I am quite happy with it and the accessories it came with.
  
  
• Very handy
  By A2EXQBT5RRFO2U on 2008-02-26
  This unit is very handy for the average homeowner. It comes with a starter supply of cutoff wheels, polishing wheels, sandpaper, etc. The battery is just average. I wish it would last longer before having to be recharged. I also wish this unit had the ability to be plugged in rather than to be solely operated by a battery. The bag gives you the ability to keep your Dremel and all the accessories in one place. I don't see how people get by without owning a Dremel. All in all, a great little tool!
  
  
• Cordless Freedom - short battery life
  By A39COBD65EU99A on 2008-05-14
  I purchased this cordless Dremel after some frustration on detailwork while doing some wood carving. The cord always seemed to alter the balance of the tool making it so incredibily difficult to be precise in softwoods - which can mean a pulled cut and a marred piece of wood and a ruined carving.
  
  The balance of the tool here is exceptional. Very easy to manipulate with a slow speed that's perfect for my application of soft wood.
  
  However... the battery life is horrific. I can work less than 45 minutes before I have to recharge the battery for 2+ hours. I very much wish I could have 3x the life and 1/2 the charging time. I need to (and don't really want to spend the money) get 2 more batteries and another charger.
