What customers say about "Key Specs"
Dremel 3000-2/28 Rotary Tool
  • Husband loves the variable speed on it which we did not have on the other one. Definite upgrade! I cannot wait to do some fine engraving with extra accessories we found in addition to what comes in the kit.
  • This particular model also has multiple speeds that range from 5,000 to 35,000 RPM and it is extremely easy to handle.
  • This particular model comes with 10 adjustable speeds and a varietyof attachments that make it project ready as soon as you open the box.
  • I like the fact that the lowest speed is lower than my old one. This is handy if you are grinding something very fragile
  • Problems with speed, only works in level 6 onwards.
  • It a good little tool to have. The only issue I'm having with it is that when its under a load at high medium to high speeds, it makes a very loud and annoying high pitch squealing that after about 30 minutes I have to take a break from it.
Dremel 4000-6/50 Variable Speed Rotary Tool
  • The Dremel tool itself is great and I really appreciate the variable speed settings.
  • It has plenty of power and the adjustable speed lets you tune the Dremel to the task at hand.
  • But this Dremel is powerful and has adjustable speed setting. It took me awhile shopping online and reading reviews to find a Dremel that would meet all my needs and this is definitely the one.
  • The tool doesn't have a lot of torque, so you need to let it operate at high speeds and let the rotational speed do the work.
  • I feel that it is worth the money to get your Dremel with a varible speed control. Speed does matter and it gives you something to play with when you get bored or just thinking things over.

What customers say about "Size & Weight"
Dremel 3000-2/28 Rotary Tool
  • It's small and can be used for a number of things.
  • It is the right size for a woman's hands and has many features. I am really glad that I purchased it.
  • This particular kit is the perfect size.
  • The 3000 will fit most any hand size, but the others above this one start to get too big for people with smaller hands. Excellent tool.
Dremel 4000-6/50 Variable Speed Rotary Tool
  • This unit works good. I previously had one of the original Dremels and finally had to replace it. They have made some real improvements. Nice size, weight and feel.
  • Not a commercial rotary tool but a light weight all around small task tool as in hobbyist tool.
  • It makes it hard to do some of the finer projects I was wanting to do because it's weight and size makes it awkward to handle.
  • The flex shaft is particually nice since it allows you to have a light weight tool in your hands for detail work.
  • I use this for my 2 Dremel work stations, drill press and router table, has the power the cordless doesn't, but the cordless is used more often for it's portability.

What customers say about "Features"
Dremel 3000-2/28 Rotary Tool
  • This set is wonderful with all the attachments/accessories which come with it. The case, itself, has room to put some of the other attachments into which we bought for it separately.
  • The carrying case makes it rather convenient to take anywhere you may need to use it. There is a smaller accessory case included which holds all of the accompanied attachments and fits snuggly inside the carrying case, keeping everything nicely organized.
  • This set is wonderful with all the attachments/accessories which come with it. The case, itself, has room to put some of the other attachments into which we bought for it separately.
  • This tool comes with 28 different accessories allowing you to use it on numerous surfaces as well as being able to use it for a wide variety of things. It can be used to sand, carve, engrave, polish, shape, grind, etc, just to give you some sort of an idea of the uses I am speaking of.
  • Lot's of cool accessories, but the mechanism that locks the dremel so you can change the bit broke after 2 uses, so now all the extra accessories it came with are useless, unless I buy another Dremel.
Dremel 4000-6/50 Variable Speed Rotary Tool
  • Comes with some nice attachments, can't wait to use the sharpener on my mower blades and see how well it works. Very pleased
  • This specific unit is extremely powerful, light, durable, and not too noisy. It includes a few bits which work well, but I wish i included more for the level of the kit.
  • The better tool ever for home or diy, probably doesn't works for heavy duty works. but so much accesories can be attached.
  • The tool is great the accesories are good but the only thing this that it did have the disk to cut wood that is my only fault with this product.
  • Great product; love that I finally have the full set with all possible attachments included in the package.

What customers say about "Power"
Dremel 3000-2/28 Rotary Tool
  • Powerful! Trimmed down a thicker piece of metal better than expected. Slight complaint. The head kept slipping off but I believe that was from the angel I was holding it.
  • This one runs a little faster and more power than the old one.
  • Much more powerful than my earlier model Dremel which is over 20 years old and still going strong. I needed a bit more power for some jobs and this tool fits the bill. Don't have a Dremel? You're missing out.
  • This model is low power, and doesn't work well with the flex shaft, because it doesn't have enough power to overcome the friction of the barrel.
  • The only reason I didn't give it 5 stars is that it would be so much better with a longer cord and perhaps a cord guide to keep the cord out of the way.
Dremel 4000-6/50 Variable Speed Rotary Tool
  • It feels solid in my hand and has good power for what it does.
  • As with all Dremel brand rotary tools, this is excellent construction, power, and versatility.
  • So I love the dremel (when it was working) great power, easy to use, simple, did everything I needed it to do, except power back up it just stopped working out of the blue and only used it a few times.
  • Be aware that you will lose some power with this extension, there were times when drilling and cutting that it would seize and I would have to turn it off, remove the tool, and start again moving slower.
  • It has plenty of power and the adjustable speed lets you tune the Dremel to the task at hand.
